     DETAILED DESCRIPTION 
     At least certain portions of the text of this disclosure (including claims, detailed description, and/or drawings as set forth herein) can support various different claim groupings and/or various different applications. Although, for sake of convenience and understanding, the detailed description can include section headings that generally track various different concepts associated with claims or general concepts contained therein, and the detailed description is not intended to limit the scope of the invention as set forth by each particular claim. It is to be understood that support for the various applications or portions thereof thereby, can appear throughout the text and/or drawings at one or more locations, irrespective of the section headings. 
     1. Certain Embodiments of a Compton Scattered X-Ray Visualizer, Imager, or Information Provider; and Associated Visualization, Imaging, or Information Providing Techniques 
     This disclosure describes a number of applications, a variety of embodiments, as well as associated techniques, pertaining to different embodiments of a Compton scattered X-ray visualizer, imager, or information provider  100  as described in block form with respect to  FIG. 1 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can visualize, image, and/or provide information pertaining to a variety of matter of at least a portion of an individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, or provide information pertaining to the matter of the at least the portion of the individual within at least one range of visualization, imaging, or information providing depth to at least one prescribed visualization, imaging, or information providing depth  170 . 
     The visualization, imaging, or information providing may result in certain instances in an application of at least one applied X-ray across at least one surface (or some other location such as with embodiments embedded in matter, tissue, etc.). Such scattered X-rays can be scattered at one or more scattering event within an at least one substantially scattered depth range to at least one prescribed substantially scattered depth. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can operate within the at least one range of visualization, imaging, or information providing depth to the at least one prescribed visualization, imaging, or information providing depth  170  within the at least one matter of the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information within a region or volume extending between at least two prescribed visualization, imaging, or information providing depths  170 . Each region or volume can be being spaced a range of depths or distances from a surface  168  (or location of the at least a part of the Compton scattered X-ray visualizer, imager, or information provider  100 ) of the at least the portion of the individual. The region or volume can be of some selected thickness, which when made thinner may approach a two-dimensional surface. 
     Certain of the “range of depths to a prescribed depth” as described in this disclosure are characterized either by the at least one range of visualization, imaging, or information providing depth to at least one prescribed visualization, imaging, or information providing depth, or alternately the at least one substantially scattered depth range to at least one prescribed substantially scattered depth. The at least one range of visualization, imaging, or information providing depth to at least one prescribed visualization, imaging, or information providing depth pertains to the region of the matter of the at least the portion of the individual that is undergoing visualization, imaging, or information providing. The at least one substantially scattered depth range to at least one prescribed substantially scattered depth pertains to the region of the matter of the at least portion of the individual to which the applied X-rays are being applied substantially down to the prescribed substantially scattered depth (as well as a potential variety of ranges of substantially scattered depth). 
     Certain X-ray photons of the applied X-rays can continue deeper into the matter of the at least the portion of the individual then the substantially scattered depth range to the prescribed substantially scattered depth and may thereupon be scattered. The visualized, imaged, or information provided regions within the at least some matter of the at least the portion of the individual can dimensionally vary considerably in different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as well as different individuals, or portions thereof. For instance, such range of depths of the prescribed depths can vary from an infinitesimal dimension, through a few to hundreds of microns, to a considerable amount of the distance through such individuals as humans or animals depending on configuration, type, use, or matter being imaged by the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     The quality, resolution, potential applications, and/or accuracy, of visualization, imaging, or information providing can vary, in different embodiments, varying from probes using one or more emitter portion(s)  150  and/or one or more Compton scattered X-ray receiving assembly  151 . The variation of the quality, resolution, potential applications, and/or accuracy, of visualization, imaging, or information providing can continue to visualizers including one or more emitter portion(s)  150  and/or the Compton scattered X-ray receiving assembly  151  can be used to obtain some depth information about at least some matter in the at least the portion of the individual. The variation of the quality, resolution, potential applications, and/or accuracy, of visualization, imaging, or information providing can further continue to sophisticated imaging systems allowing for detailed visualization, imaging, or information providing. 
     Within this disclosure, including the appended claims, the terms “imaging”, “visualization”, “probing”, and/or “information providing” can, depending context, be considered as being included within the inclusive term “visualization, imaging, or information providing”. Within this disclosure, certain embodiments of the Compton scattered X-ray receiving assembly  151  could be at least partially internal to the individual, at least partially external to the individual, configured as a complete unit, and/or configured as a number of combined units at least some of which may interact together. 
     Certain embodiments of the one or more emitter portion(s)  150  and/or the one or more Compton scattered X-ray receiving assembly  151  can be configured as discrete units, arrays of distinct devices, or alternately as arrays of composite devices made using such processes as semiconductor processing, very large scale integration (VLSI), ultra large scale integration (ULSI), and/or other known semiconductor or other manufacturing processes. The depth visualization, imaging, or information processing associated with the one or more emitter portion(s)  150  and/or one or more Compton scattered X-ray receiving assembly  151  should be selected to be suitable for operation of the particular device(s), as well as the potential user input. 
     The associated visualizing, imaging, information providing, and/or processing technologies can therefore be designed, used, and/or scaled based, at least in part, on the sophistication and complexity of the Compton scattered X-ray visualizer, imager, or information provider  100  performing the visualization, imaging, or information providing. Compton scattered X-ray visualization, imaging, or information providing can be performed by a variety of either at least partially internal embodiments, and/or at least partially external embodiments. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in the disclosure, can be at least partially generalized to, and generally at least partially operate according to, the disclosure as described with respect to the  FIG. 1  block diagram. 
     For a variety of reasons, in general, certain conventional types of visualization, imaging, or information providing can perform certain activities of types of diagnosis better or worse than others. This disclosure describes a number of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that may each be configured for visualization, imaging, or information providing such as to detect particular illnesses, injuries, cancers, tumors, bone conditions, teeth, implants, etc. in either a devoted or multi-purpose manner. The  FIG. 1  embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , shown in block diagram format, can be applied to a variety of configurations as well as applications, etc. 
       FIG. 2  shows, in general, a scattering event associated with an X-ray photon of an applied X-ray  120  contacting a target electron  120  (the target electron may be included in the “matter” of the individual as described in this disclosure) to form the X-ray photon of a scattered X-ray  122 . The X-ray photons of the applied X-ray  120  generally lose energy during its transition to the scattered X-ray  122 , as a result of the energy transferred/used by scattering within the scattering event. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby include, but is not limited to, the at least one emitter portion  150  as well as the at least one Compton scattered X-ray receiving assembly  151 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  can visualize, image, and/or provide information which can thereupon be analyzed, displayed, computed, and/or processed, etc. Certain embodiments of the at least one Compton scattered X-ray receiving assembly  151  can include, but is not limited to, at least one detector portion  152  and/or the at least one display portion  154 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider may allow the visualization, image, or information provided to be captured and/or combined based at least partially on: deconvolution, transform (e.g., integral transform, inverse Fourier transform, inverse FFT, etc.), image subtraction, weighted subtraction, functional subtraction, weighted subtraction, functional subtraction, inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such processes or computations. Such visualization, imaging, or information providing may occur either on a one time, multiple times, repetitive, continuous, or other similar basis, perhaps in an as-programmed, user controlled, as-desired, or other suitable manner. 
     Within this disclosure, deconvolution techniques can be used to limit or reduce the obscuring effect(s) of depth of matter, tissue, X-ray opaque matter, noise, etc. as applied to cloud desired images, etc. As such, deconvolution can be used to clarify the visualization(s), image(s), and/or provided information. Deconvolution techniques and technologies are well established and understood, and have been in use in certain technological areas since prior to World War II. Deconvolution is conventionally used in image processing, signal processing, and other computer-based imaging techniques. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize deconvolution, transforms, and other distortion diminishing techniques. Such distortion diminishing techniques may be used to limit distorting effects resulting at least partially from, for example: X-ray opaque matter, obscuring matter, signal noise, etc. such as to identify or visualize aircraft hidden in clouds, limit signals and/or images in noisy backgrounds, etc. Other such distortion-limiting image processing techniques may be applied, where appropriate, in a manner as would be obvious to one skilled in the art. 
     The “matter” of the human or animal individuals can, depending upon context include, but is not limited to: tissue, flesh, muscle, optically opaque tissue, organ(s), bone(s), bone part(s), hair, bone fragment(s), implant(s), fat, blood vessel(s), blood capillary(s), skin(s), teeth, epidermis, dermis, brain, tumors, cysts, contrast agents such as iodinated contrast agents, gadolinium, certain fluid(s), blood or blood component(s), CSF, irrigant, IV fluids, water, aqueous solutions, implant materials such as ceramic, steel, titanium, nitinol, etc. Plant and organism embodiments can include such matter (naturally occurring or man-made or applied) that can be imaged, depending on the structure and/or location being imaged as a portion of, and/or associated with, the plant or organism. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can achieve relatively high resolution of their depth visualizations, images, and/or information provided. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured such that the matter of the at least the portion of the individual can be inclusively imaged as at least a portion of the individual  82 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can depth visualization, image, and/or provide information relating to a considerable number of distinct types of matter as compared with, for example, certain conventional X-ray techniques. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby visualize, image, and/or provide information relating to such matter of the at least the portion of the individual as such tissue as flesh, tissue, muscle, fat, fluid (blood, lymph, spinal fluid, etc.) in a controllable and/or adjustable manner. In this manner, an initial depth visualizing, imaging, or information providing can be performed of a region, and upon locating areas of interest, the Compton scattered X-ray visualization, imaging, or information providing can be filtered, processed, analyzed, compared, transformed, adjusted, magnified, angled, etc. as described in this disclosure to visualize, image, and/or provide information relating to desired regions. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used to visualize, image, and/or provide information relating to the spine of humans or animals, such as may be the case with certain spinal surgeons. Such depth visualizing, imaging, or information providing of spine (as well as associated plates, pins, blood vessels, muscles, etc.) can be performed prior to, during, and/or following surgery; and can provide imaging, visualizing, or provide information of appropriate or desired quality depending on the desired purpose, equipment, condition, or application. Such Compton scattered X-ray visualization, imaging, or information providing following surgery can be provided at one or more suitable angles, such as to illustrate interaction with plates, pins, constructs, etc. relative to the spine, associated nerves, bones, and associated pins, constructs, etc. Those embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are configured to image the matter, spine, bones, tissue, implants, etc. should be configured based on the desired depth imaging, depth visualizing, and/or examination, and may be adjusted and/or controlled, perhaps on a near real time basis. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to the figures, and at other locations through this disclosure, primarily pertain to displays that can display visualizations and/or images over various embodiments of the Compton scattered X-ray receiving assembly  151 . By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 38  and at other locations through this disclosure, primarily pertain to displays that can display information in such a form as text, data, graphs, or other processed information, or a combination or modification thereof, etc. More particularly,  FIG. 38  illustrates an example of text, data, etc. being presented in other non-image or non-visualization form. The various embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can also include a graphical user interface, buttons, switches, or other mechanism to allow a user or individual to provide input as to the visualization, imaging, or information providing as desired, suitable, and/or designed. As such, within this disclosure, each of the terms “visualize”, “image”, or “provide information” is, depending on context, intended to be inclusive of each of these terms. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured for a variety of particular applications. The user of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may select a particular aspect such as quality, refresh rate, real-time aspects, resolution, color, etc. based on the particular task at hand. For example, a doctor examining a patient&#39;s external skin may obtain one or more visualizations, images, or provided information, or may treat certain surface aberrations using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Also, a surgeon/user who is using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that may be attached, integrated, or otherwise secured to a surgical tool which can be used in such procedures as cutting, separating, ablating, deforming, processing, tactile feedback providing, adding material, removing material, or otherwise handling matter such as tissue, bone, fluid, blood, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be satisfied with relatively various quality depth visualizations or images that can range from very detailed or excellent images to relatively sketchy images. Detailed images, for example, can provide an excellent representation of the matter of the at least the portion of the individual. Relatively sketchy visualizations can be adequate to indicate a relative position of a desired visualized item such as a blood vessel, bone, portion, nerve, construct, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be provided at a refresh rate sufficient rate to operate as desired, or operate a tool in combination as desired without contacting blood vessels, nerves, or other matter to be protected within the individual, for example. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be associated with a variety of tools, and can be used to assist in deforming, separating, distorting, guiding, cutting, avoiding, and other such embodiments of the tools. 
     Certain tools that can be associated with, or operatively coupled to, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide tactile feedback to a user. Such tactile feedback providing tool can be used particularly in combination with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as to allow the user to “feel” or “touch” the various regions of the individual for treatment or examination purposes (even if only remotely while similarly observing the region). While tactile feedback mechanisms may not be shown in the figures; this is generally understood by those skilled in the robotics, automation, surgical, and other such arts or technical areas. Certain orthopedic surgeons, etc., who are interested in general positions of such particular matter as bones, organs, etc. may be satisfied with depth visualizations and/or images that have limited resolution or image quality. As such, certain embodiments of the tactile feedback provider may be considered as “tools” within certain meanings and/or certain contexts as applied within this disclosure. Additionally, certain users may select to use certain scintillator or fluoroscope embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     A user may desire to use certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to image, visualize, image, and/or provide information at a considerable depth into tissue, and/or obtain depth visualizations or images that may have a high resolution or quality. Certain visualizations or images that can be produced by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be of similar quality of MRI, CAT Scans, PET scans, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be performed relatively quickly as compared with conventional imaging modalities, such as in certain instances to be applied on a near-real time basis. The user may thereupon select to use certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that rely upon consider image processing to achieve suitable visualization, imaging, or information providing quality, as described in this disclosure. As such, the user can select one or more suitable embodiments of the Compton scattered X-ray visualizer, imager, or information provider based, at least in part, on the particular task at hand. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied from a variety of embodiments of mechanisms that can be configured to provide visualization, imaging, or information providing structures, including depending on context, but not limited to: platforms, tables, hand-held, endoscopes, attached to or integrated within a tool, etc. Within this disclosure, the description of the particular visualization, imaging, or information providing structure being used is intended to be illustrative in nature but not limiting in scope. As such, it is intended that a description of an embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  being applied to a particular visualization, imaging, or information providing structure may be applied to other visualization, imaging, or information providing structures, while remaining within the scope of the present disclosure, depending on context. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize results from scattering events to determine the amount of energy loss and/or change in direction of the X-ray photons resulting from contact (or close interaction) with electrons, neutrons, protons, or other portions of atoms and/or matter. The energy level variation (almost always a loss as a result of conservation of energy principles) of the X-ray photons of the applied X-ray  120  that, upon the scattering event, becomes the scattered X-ray  122 , and the scattered energy level can be used to derive the energy transfer based on Compton equations as described with respect to  FIG. 2 . The scattering angle of the scattered X-ray resulting from the scattering event, and position of the scattering event, can be derived based upon a combination of: a) the initial energy level and trajectory of the applied X-ray, b) the detected position of the Compton scattered X-ray receiving assembly  151 , c) the scattered energy level of the scattered X-ray  122 , and d) the energy loss resulting at least partially from the scattering event. The scattering angle and position of the scattering events can to be determined based at least partially on the Compton scattered X-ray equations used herein, as well as geometric equations. By compiling a large number of scattering angles and positions of scattering events by one or more of the Compton scattered X-ray receiving assembly  151 , an image can be derived having a continuously improving image quality. 
     Compton scattered X-ray visualization, imaging, or information providing can be performed using a variety of mechanisms and involving a variety of techniques. Determination of the depth within matter of the at least the at least the portion of the individual that is being visualized, imaged, and/or information provided, can be at least partially derived involving analytical determination, computation as well as numerical calculation such as can be performed by computers and/or controllers; or alternately can involve experimentation or analysis. Certain aspects of visualization, imaging, or information providing can be based on such factors as each particular matter being visualized, imaged, or information provided, the energy level and/or frequency of the X-ray photons of the applied X-ray  120  and/or scattered X-ray  122 , and/or other such factors. Certain versions of such visualization, imaging, or information providing that rely on tomography may result from generating a series or number of relatively thin slices, that by being relatively thin can enhance visualizing, imaging, or image providing consistency or homogeneity across each slice. 
     Consistency of the matter being visualized are imaged across the thickness can thereby improve imaging quality, especially in the direction parallel to a direction at which the visualization, imaging, or image providing be being performed (e.g., through the thickness of the visualizing, imaging, or information providing axis slice). Similarly, imaging quality may diminish in certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as the matter becomes more heterogeneous across the thickness of the imaging slice. Such visualization, imaging, or information providing may be taken in a straight, curved, complex, or some other desired or suitable or desired shape. 
     Certain techniques similar to those that provide slices, such as used in conventional tomography imaging techniques, can also be applied to certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of the slices as can be utilized during visualization, imaging, and image providing by the Compton scattered X-ray visualizer, imager, or information provider  100  can be arranged in a straight, curved, complex, or some other desired or suitable or desired shape. Combining a number of the slices, which may be considered as a three dimensional region of visualizing, imaging, or information provider having a limited thickness that can be imaged by the Compton scattered X-ray visualizer, imager, or information provider  100 , can produce a thicker image of the particular matter. This disclosure initially describes a variety of techniques for such Compton scattered X-ray visualization, imaging, or information providing. 
     Certain embodiments of visualization, imaging, or information providing can be used to visualize, image, or provide information within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth (e.g., from a surface, or alternately spaced from the surface). The actual or maximum at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth being visualized, imaged, or information provided may vary between different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , and may be based on particulars of the scattered X-ray depth visualizing, imaging, or information providing; the matter undergoing depth visualizing, imaging, or information providing; as well as the processor characteristics and operation of the visualization, imaging, or information providing controller  97 . Some of the X-ray photons of the applied X-ray scatter to provide the scattering event wherein the scattered X-ray may scatter at a depth greater than the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth. 
     Based on the energy level of the X-ray photons of the applied X-rays, the number of applied X-rays with the scattering event occurring at the range of depths greater than the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth can, for certain visualization, imaging, or image providing, can be assumed to be ignored either computationally, be effectively filtered out, limited by weighting techniques, or removed using image processing techniques; or even accepted. Certain visualizations, images, or provided information can be provided even by ignoring a limited percentage of deeper scattered X-rays. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to limit the effects of the X-ray photons of the Compton scattered X-rays  120  that are returning from the scattering event occurring through greater depths than the at least one substantially scatted depth range to the at least one prescribed substantially scattered depth  170 . Additionally, certain of the depth visualizing, imaging, or information providing effects of these X-ray photons of the Compton scattered X-rays  120 , that scatter at the range of scattering depths greater than the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth, can be included with at least some of the distorting effects either ignored, filtered, and/or otherwise limited using image processing techniques, deconvolution, and other techniques. 
     Another embodiment of Compton scattered X-ray visualization, imaging, or information providing can control or adjust the depth visualizing, imaging, or information providing at least partially by increasing, such as by ramping up, the energy of the photons of the applied X-rays. By changing the energy level or frequency of the X-ray photons of the applied X-ray  120 , the effective range of visualizing, imaging, or information providing depth to the prescribed visualizing, imaging, or information providing depth into the matter of the at least the portion of the individual can change. As such, the energy level and/or frequency of at least some of the X-ray photons of the applied X-rays that are being used to visualize, image, and/or provide information can be tuned as to effect variation in depth of the Compton scattered X-ray visualization, imaging, or information providing. 
     Within this disclosure, the term “individual” can, depending on context, pertain to a person, animal, plant, organism, of whom at least a portion thereof is being imaged and/or examined by the Compton scattered X-ray visualizer, imager, or information provider  100 . The term “user” can, depending on context, pertain to those persons using and/or operating certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as, but not limited to: doctors, physicians, dentists, veterinarians, researchers, assistants, technicians, researchers, persons performing medical forensics and/or autopsies, users, and/or other persons, assistants to, derivatives from, etc. who can view or utilize the visualized, imaged, or information provided portion of the individual using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Within this disclosure, the term “user” can also include, in addition to the human users as described above: computers, automated systems, controllers, robotic devices, other devices etc. that can be used to automate visualization, imaging, providing information, inspection, or analyzing of certain depth image information as output by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Consider, for example, that certain depth image information can be more readily utilized or processed by computers based on computer-vision, machine based imaging, machine vision, machine-based devices, etc. to determine certain aspects thereof. For example, certain computer-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are being associated with surgical tools might be adapted to quantitatively determine or interpret the relative depth of certain blood vessels, nerves, etc. Such visualization, imaging, or information providing may be effective in the vicinity of non-homogenous matter, for certain embodiments. 
     Certain computer-based or machine based embodiments of the Compton scattered X-ray visualizer, imager, or information provider may prove quite effective at visualizing, imaging, information providing, or otherwise analyzing through particular X-ray opaque matter (perhaps at least partially relying on deconvolution, transforms, or other such techniques to limit the obscuring effects). Such techniques may accomplish such tasks as determining depths of cancer, tumors, bones, or other matter within the individual, and may thereby limit, reduce, or double-check the human scanning over large regions of the individual has be performed. Certain computer based embodiments, (or even human-vision embodiments) of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured in home-test form, emergency form, task-specific form, relatively low power form, or even in a form that can be used without the assistance of a skilled user. As such, within this disclosure, in certain instances, particularly with certain simplified or devoted embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the term “user” can also include the individual, the individual&#39;s family or friend&#39;s thereof, and/or care providers for the individual who can assist in operating certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider for the individual. Certain such home-test embodiments of the Compton scattered X-ray visualizer, imager, or information provider might preferably be used for one, or a few, devoted purposes such as, but not limited to: mammograms, cancer or tumor screening, blood flow, tissue aberrations, possible bone break or tissue tear, etc., as described in this disclosure. 
     Certain computer vision based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to model certain matter aberrations within the at least the portion of the individual perhaps using, or without, deconvolution, transform, or other such techniques. Certain computer vision based embodiments of the Compton scattered X-ray visualizer, imager, or information provider may prove superior to certain human-vision embodiments in determining extent, dimensions, degrees, etc. of certain aberrations, such as melanomas, tumors, cancers, bone growth, etc., the scattered X-rays by using mapping techniques such as are commonly used in tomography, MRI, and other conventional imaging techniques. 
     Within this disclosure, Compton scattered X-ray visualization, imaging, or information providing can, depending on context, pertain to depth visualizing, imaging, or information providing of a volume of matter that can have an arbitrary thickness depending on the desired visualization, imaging, or information providing application, but may be considered to be three dimensional. The three dimensional volume (having some thickness) being visualized, imaged, or information provided can be at least partially separated from an internal or external surface such as external skin or membrane, internal lumen, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be positioned at regions adjacent the surface  168  to provide some location that can be used to relatively position to visualize, image, and/or provide information relating to portions of the individual. The surface  168  of the individual can provide some location at which certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be positioned, angled, moved, or otherwise displaced to enhance the visualization, imaging, or information providing. As such, in certain instances, proximate or adjacent the surface can provide a good location from which to visualize, image, or provide information. 
     As described with respect to  FIG. 1 , as well as at other locations in this disclosure, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include, but are not limited to, at least one emitter portion  150  and/or at least one Compton scattered X-ray receiving assembly  151 . Certain embodiments of the at least one emitter portion  150  can be configured to emit or direct at least some applied X-rays  120  toward the at least the portion of the individual  82 . Certain embodiments of the at least one emitter portion  150  can be adjustable and/or controllable such as to be able to respectively control and/or adjust generation and/or direction of the applied X-rays being applied to the at least some matter of the at least the portion of the individual. At least some of the applied X-rays are thereupon scattered within the scattering event to form the scattered X-rays, which can thereupon be received by the at least one Compton scattered X-ray receiving assembly  151 . Certain embodiments of the at least one emitter portion  150  can be used to adjust or control the at least one visualizing, imaging, or information providing within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Within this disclosure, the applied X-ray  120  or the scattered X-ray  122  can include (e.g., comprise) a number of X-ray photons whose characteristic energy level and/or frequency can dictate the characteristics of the X-ray beams. 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  can be configured to detect at least some Compton scattered X-rays  122  being Compton scattered from the at least the portion of the individual  82 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  can operate based, at least in part, by receiving scattered X-rays  122  from a first Compton scattered X-ray visualizer, imager, or information provider  100  scattered of scattering of events from applied X-rays  120  that were generated by a different Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  are controllable and/or adjustable such as to be able to respectively control and/or adjust the characteristics of the at least some Compton scattered X-rays  122  that can be detected. Certain embodiments of the at least one Compton scattered X-ray receiving assembly  151  can include, but is not limited to, each, or any combination of the at least one detector portion  152  and/or the at least one display portion  154 . 
     The operation of certain embodiments of emitter portion  150  and/or the Compton scattered X-ray receiving assembly  151  may be at least partially controlled or adjusted utilizing at least partially by the visualization, imaging, or information providing controller  97 , as described in this disclosure (although certain embodiments utilize relatively little or no control and/or adjustment). Certain embodiments of the Compton scattered X-ray receiving assembly  151  can visualize, image, and/or provide information relating to the at least the portion of the individual  82  based, at least in part, on detecting the Compton scattered X-rays  122  Compton scattered from the at least the portion of the individual. The structure and operation of certain illustrative, but non-limiting, embodiments of each of the respective at least one emitter portion elements  150 , at least one Compton scattered X-ray receiving assembly  151 , at least one detector portion elements  152 , and/or at least one display portion elements  154  are described in considerable detail in this disclosure, including the specification, claims, and/or figures. 
     The potential variety of visualization, imaging, or information providing, as described in this disclosure, can indicate the variety of potential embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  which can vary in complexity from relatively simple probes to relatively complex systems. More complex systems can include arrays of a considerable number of the emitter portion(s)  150  and/or a considerable number of the scattered X-ray receiving assemblies  151 . The different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be arranged in a variety of suitable configurations. Certain embodiments of the scattered X-ray receiving assemblies  151  can be used to determine a location of scattering events based at least partially on the applied X-ray energy level, position, and trajectory of the applied X-ray  120 , as well as the scattered X-ray location and energy level of the scattered X-ray  122 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can, depending on context, be fabricated using a range of devices, systems, or fabrication techniques ranging from distinct components to semiconductor processing, and may involve suitable image processing, hardware, and/or software, etc. to perform suitable image deconvolution, transforms, filtering, modulation, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are configured to operate in association with at least one tool portion relative to, for example, at least some matter of the at least the portion of the individual. The particular component and/or configuration selected may depend, at least in part, on the application of the Compton scattered X-ray visualizer, imager, or information provider  100  and/or the associated tool. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be associated with a particular tool, including but not limited to: a cutting tool, a scalpel, a gamma knife, a laser cutter, a tactile feedback provider, an ablator, a scope, a Bovie electrocautery device, a material adding tool, a material removing tool, etc. such as to allow a user to search, image, or visualize within a particular region for a specific component, chemical, etc. as a tool-based process is being performed. Such imaging, visualization, or information providing may be used relative to the location of blood vessels, cancer, tumors, organs, etc. Alternately, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to detect, visualize, image, and/or provide information relative to an area of potential interest, such as a field of surgical operation, within the at least the portion of the individual in which at least the at least the portion of the individual. 
       FIG. 3  illustrates an embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  being configured to have one or a few emitter portion(s)  150 , as well as one or a few scattered X-ray receiving assemblies  151 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  may utilize suitable X-ray detection such as depth subtraction or combination, time of flight, and/or scintillator (and/or fluoroscope) aspects, as described in this disclosure. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can operate, by at least one of the emitter portion(s)  150  emitting the X-ray photons of the applied X-rays  120 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can operate along a specific direction or prescribed depth into the at least some matter of the at least the portion of the individual that can scatter upon the scattering events within the matter of the at least the portion of the individual. Certain scintillator or other embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize convolution or deconvolution, one or more transforms and/or inverse transforms, and/or other techniques to increase imaging quality of visualizing, imaging, or information providing, etc. through X-ray opaque or other matter. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide an image deconvolution operation that can clarify between scattered X-rays returning to the Compton scattered X-ray receiving assembly  151  from a number of separated, but closely aligned, scattering events. 
     A number of X-ray photons can be expected to scatter within the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth at least partially from the scattered X-ray. The particulars of the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth will correspond, at least in part, on the energy level of the X-ray photons (which corresponds to the frequency of the X-ray photons of the applied X-rays  120 ). It might be desirable to simplify at least certain of the embodiments or applications of the Compton scattered X-ray visualizer, imager, or information provider  100 . Simplification might be for such purposes as to reduce expenses, simplifying image processing or system computations, focusing on depth visualizing a single or a few aberrations, such as melanomas, tumors, cancers, tissue edges, blood pools, blood vessels, liquids, organ edges, tissue matter change delineations, etc. 
     Certain of such embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to image a particular material, element, chemical, fluid, fluid flow, solid, or other detectable aspect. For instance, certain of these embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be attached to a probe, tool, cutter, tactile feedback provider, laser device, Bovie electrocautery, separator, visualizer, imager, etc. 
     Certain tool-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be placed on the end of a probe that is inserted into the body. For example, as a probe or other tool passes through tissue (e.g., brain, heart, or other organ or even flesh, muscle, etc.) an alarm that could be audio, video, or other can be set off which notifies the user that the probe is coming into close proximity to a blood vessel or other sensitive location. Another example is this could be part of a drill (e.g., such as could be used to penetrate the pedicle of the spine or by a dentist), such as it could notify the user if the drill tip is coming into too close proximity to adjacent vital structures such as a nerve root, spinal canal, or artery. Still another example is that this is attached to an electrocautery instrument that will terminate current flow when the instrument is passing too close to defined danger zones such as blood vessel, nerve, vital organ structure, etc. 
     Certain surgeons operating in a manner to avoid blood vessels, nerves, etc. (while often necessary to keep their patient healthy and/or alive) can be slow and/or laborious in certain circumstances, and can considerably extend the duration of operations. The presence of blood vessels, nerves, etc. in locations where surgeons may not clearly see via their tools due to a skewering matter, tissue, bones, etc., can also result in additional risks to the patients (e.g., individuals). Surgeons attempting to operate too quickly can risk the likelihood of injury, or even death, to their patients by contacting, severing, or rupturing their blood vessels, nerves, brain tissue, or other organ and/or matter. Allowing a surgeon to detect blood vessels, nerves, spinal portions, sensitive tissue, etc. can be utilized in an attempt to operate in, or negotiate around, a sensitive matter or region without contacting the sensitive matter or region by, for example, visualizing, imaging, providing information, the sensitive matter or region. Such allowing surgeons to effectively determine relative locations of tools, etc. to sensitive matter or regions could therefore be expected to increase the rate at which surgeons might safely be able to operate while safely negotiating past the sensitive matters or regions within the individual, as well as increasing the rate at which they can safely and accurately operate. 
     If more than one emitter portion  150  are operating, then there should be some mechanism to limit confusion between the applied X-rays provided by each emitter portion as detected by certain embodiments of the Compton scattered X-ray receiving assembly  151 . Such differentiation or combination of scattered X-rays at each Compton scattered X-ray receiving assembly  151  between the applied X-rays  120  being generated by each of the emitter portions  151  can rely on, for example: altering the transmission time, coding of the carrier signal, differentiating signal weightings, shifting frequency of the applied X-rays  120  between the different ones of the applied X-rays, altering the energy levels of the photons altering the pulse durations of the applied X-rays, etc. as described in this disclosure. Otherwise differentiating each of the applied X-rays  120 , and/or the directing at least certain ones of the applied X-rays  120  in a different direction along non-interfering directions and sets of potential scattering events, such that the scattered X-rays returning from different scattering events can be distinguished from each other each other. Such techniques similar to deconvolution, inverse transforms, time division multiplexing, frequency division multiplexing, code division multiplexing, etc. (which are known to those skilled in the communications arts) can be utilized to distinguish between, or clarify, different applied X-rays being received by different emitter portion this  150 , and thereby limit interference at the at least one Compton scattered X-ray receiving assembly  151  between multiple ones of the scattered X-rays scattered from different scattering events. 
       FIG. 4  illustrates another embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be configured with one or more of the emitter portions  150 , as well as one or more Compton scattered X-ray receiving assemblies  151  (similar to as described with regards to  FIG. 3  to that illustrates only one emitter portion). Multiple ones of the emitter portion  150  may, or may not be, arranged in a desirable associated relative configuration, such as at least one array, conforming to the matter, etc. Certain embodiments of the emitter portions  150  can be configured to emit the applied X-rays  120  (as well as the scattered X-rays  122 ) in a manner that can be differentiated from other ones (as well as other scattered X-rays  122 ) based at least partially on deconvolution, transforms, time multiplexing, frequency multiplexing, code division multiplexing, directing of a variety of X-ray beams such as pencil beams, fan beams, etc. to a desired location, and/or other such scattering event differentiating techniques, use of collimators, lenses, filters, etc. For example, certain embodiments of the multiple emitter portions  150  can emit their applied X-ray at different deconvolution or transform characteristics at different times, having different frequencies, with different weightings, or based on different coding algorithms such as is generally understood with a variety of multiplexing techniques. Certain such embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be utilized as a visualizer having limited resolution; and may provide especially useful in conjunction with a tool as to provide visualization, imaging, or information providing for blood vessels, cancer, or other aberrations to visualization, imaging, or information providing as described in this disclosure. 
     Certain embodiments of the one or more Compton scattered X-ray receiving assemblies  151  can include a streak camera, a pixellated streak camera, an avalanche detector, a CCD device, or other device that can detect the presence, energy level, and/or condition of scattered X-rays, preferably at a suitable rate to provide the desired resolution. Certain embodiments of the streak camera and/or the pixellated streak camera might be configured to act quite quickly, and certain ones can function in the low or fractional picosecond range, such as may be particularly useful for time of flight calculations. 
     Certain embodiments of Compton scattered X-ray visualizer, imager, or information provider  100  can include one or more collimated (e.g., “pencil”, “fan”, or other) beam of the applied X-rays  120 , as illustrated in  FIGS. 3 and 4 . Certain embodiments of these beams can scan the at least the portion of the individual in two directions while the one or more scattered X-ray receiving assemblies  151  can measure the Compton scattered X-rays resulting from the interactions of the primary X-rays with the bodily tissues. A variety of depth visualizing and/or imaging information, particular to a given 3-D voxel within the display of the one or more scattered X-ray receiving assemblies  151 , can be derived using the two-dimensionally scanned X-ray beams, which can be detected in several ways as described herein. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize time-resolved detection of the scattered X-rays  122 . Here, the time-of-return, Δt, of each scattered X-ray from a scattering event corresponding uniquely to a position, x, along the illuminating collimated X-ray beam, such that:
 
 x=A*Δt+B   (1)
 
     where A and B are proportionality constants determined by the relative location of the illuminating X-ray beam and the X-ray detector. There can be a sufficient temporal pause (or other time, spatial, or coding technique understood by those skilled in multiplexing) between illumination at specific 2-D ray angles to limit scattered signal confusion between multiple ones of the scattered X-ray is received at each Compton scattered X-ray receiving assembly  151 . If determined to be significant, the background from multiple scattered X-rays can be reduced by adding energy discrimination to the detector, since each scattering event results in a reduction in X-ray photon energy levels. For example, energy is lost by the moving X-ray photon particle during collisions with other moving particles forming the matter of the at least the portion of the individual, that can be described based on Newton&#39;s equation, Compton&#39;s equation, as well as other geometric or other equations, as described in this disclosure or elsewhere but generally known. 
     By scanning the body repeatedly in one, two, or three orthogonal directions, but at varying energies so that the radiation penetrates progressively more or less deeply so scattering events can occur up to a progressively respectively deeper, or shallower, prescribed depth. Thereupon, a model (which may be three or two dimensional) of the subcutaneous bodily structures can be progressively refined by comparing it to the time-integrated backscattered X-ray return from each illuminating beam angle and then performing a de-convolution similar to those used in tomography imaging. In addition to helping provide depth discrimination, such progressive illumination at different energies can reveal differences in the absorption and/or scattering characteristics of various scattering events occurring in particular matter. The value of the scattering characteristics of a scattering event can be an enhanced or diminished, in certain instances, by adding contrast agent, etc., such as to increase the contrast of the resulting image. In certain instances, the energy level of the applied X-ray can be increased, decreased, ramped, and/or otherwise altered (preferably in a gradual and/or predictable manner as described elsewhere in this disclosure, such that changes in the energy level will have little effect on imaging distortion) such as to allow adjustability or control of the visualizing, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to operate in some controlled combination of the techniques as described in this disclosure. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be configured to visualize, image, and/or provide information at least partially by employing a nearly monochromatic illuminating X-ray “pencil” beam, flooding beam, fan-beam, scanning beam, or other such emitter portion  150 . The location of the scattering events along one or more of the beam of the applied X-ray (in which, in certain instances, multiple ones thereof can be intersected to increase the intensity) can be determined where the X-ray photon of the scattering X-ray scatters based on the unique relation between the change in its wavelength, Δλ, and its scattering angle, θ. For the usual case of the scattering events for each once-scattered X-ray photon, the change in wavelength of the X-ray photon upon scattering is given by the Compton formula:
 
Δλ= h (1−cos θ)/ mc   (2)
 
     where h is Planck&#39;s constant, m, the mass of the electron, and c, the speed of light. 
     If necessary, time resolution, directional resolution, deconvolution, or other such image combination techniques can be added to at least certain of the approaches, as described in this disclosure, to assist in suppressing background noise or other distorted affects from scattered X-rays emanating from scattering events. Such image combination techniques can include, but are not limited to, image subtraction, image differentiation, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other image processing techniques. 
     A number of other embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are described, which can be configured to determine the location of scattering at least partially based on some characteristics of the scattered X-rays being received at the Compton scattered X-ray receiving assembly  151 .  FIG. 5  illustrates an embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  that are configured with one or more of the emitter portions  150 , and/or one or more of the scattered X-ray receiving assemblies  151 . Consider that certain embodiments of the Compton scattered X-ray receiving assemblies  151  can be configured with one or more of the emitter portions  150 , as well as one or more scattered Compton scattered X-ray receiving assemblies  151 . The one or more emitter portion  150 , as described with respect to  FIG. 5 , can be configured as a pencil beam emitter, a fan emitter, or other emitter that can controllably direct the applied X-rays  120  as desired or designed in a particular path or direction and/or we associated X-ray photons having a particular energy level. For example, if there are a number of the one or more emitter portion(s)  150 , then each one may be configured or designed to emit the X-rays along a controllable direction, time, angle, depth, etc. such as to not interfere with others. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured and/or designed such that the applied X-ray  120  of  FIG. 5  can be directed along an emitted X-ray path  120 ′, that extends substantially continuously in a prescribed direction. While  FIG. 5  illustrates the applied X-ray  120  being substantially perpendicular across the surface into the matter of the at least the portion of the individual, some other angle can be provided with the surface as well, and still comply with Compton equations as described with respect to  FIG. 2 . At least one Compton scattered X-ray receiving assembly  151  (illustrated in  FIG. 5  as an array of receiving assemblies) is situated at an angle relative to the applied X-ray  120 , and can thereby be configured to receive a variety of scattered X-rays  122 ′,  122 ″, etc. that have been scattered at a variety of illustrative locations  152 ′,  152 ″, etc. that have been scattered from a scattering event situated along the path of the applied X-ray  120 . The location of each scattering events  152 ′,  152 ″ can be situated along the path of the applied X-ray  120 , can be determined based, at least in part, on scattering angle, θ 1  and θ 2 , etc., the X-ray photons of the scattered X-ray can exhibit at different energy level (corresponding to different X-ray photon frequency). For example, the greater the scattering angle θ (such as θ 1  and θ 2  in  FIG. 5 ), the greater the associated energy loss. As such, based on the energy level of the X-ray photon within the scattered X-ray  122 , the scattering angle θ (such as θ 1  and θ 2  in  FIG. 5 ), as well as the scattering events location  152 ′,  152 ″, can be derived utilizing equation 2, as described above. Various embodiments of various computations, certain ones as described in this disclosure, can be used to locate the position of the scattering events  152 ′,  152 ″, etc., can be derived based at least in part on deconvolution, transforms, etc. to provide geometric visualization, imaging, or information providing techniques, etc. a number of one, two, or three-dimensional arrays of the Compton scattered X-ray receiving assembly  151  can be arranged to about the applied X-ray  120 , in a manner to enhance the determination of the position of the scattering events  152 ′,  152 ″. Such determination can be based at least in part on the location of the multiple received arrays of the Compton scattered X-ray receiving assembly  151 . 
     The  FIG. 5  embodiment of the Compton scattered X-ray receiving assembly  151  can be used to derive at least one position of the scattering event  152  in which X-ray photons of the applied X-ray  120  is scattered such as by contact, or traveling close to: atoms, electrons, neutrons, or other such matter. The embodiment of the emitter portion  150  as described with respect to  FIG. 6  can be similar, or identical, to those embodiments as described with respect to  FIGS. 1 to 9 , as well as other locations in this disclosure. Certain embodiments of the Compton scattered X-ray receiving assembly  151 , as described with respect to  FIG. 6 , can include a slit collimator  172  or other such device that can limit the angle at which scattered X-rays can reach the Compton scattered X-ray receiving assembly  151 . Certain embodiments of the collimator can also be configured as a lens, filter, correlator, or other device that can be used to limit passage of the scattered X-rays to the Compton scattered X-ray receiving assembly  151  to only within a range of degrees, etc. Certain embodiments of the slit collimator, lens, filter, etc. could be provided between the path of the applied X-ray  120 ′ and the Compton scattered X-ray receiving assembly  151 . Those scattered X-rays being applied from the position of the scattering event of the Compton scattered X-ray receiving assembly  151  will only be detected if flowing in a direction substantially aligned with the slits of the slit collimator. The structure and use of slit collimators, lenses, filters, etc. are generally understood by those skilled in the optics, X-ray, electromagnetics, and other similar areas; and will not be further described in this disclosure. Alternate types of collimators, lenses, filters, etc. that can limit the passage of the scattered X-rays to those within an angular range such as to detect scattering events within that angular range may also be utilized. 
     Only one slit is shown in the slit collimator  172  as illustrated in  FIG. 6 . One or more of the slits of the slit collimator  172  can be arranged, such as to be aligned with only a particular element of the Compton scattered X-ray receiving assembly  151 . While a single slit collimator is described with respect to  FIG. 6 , it is to be understood that multiple slit collimators can be respectively associated with at least one unit of the Compton scattered X-ray receiving assembly  151 . In addition, utilizing one or more of a variety of technologies that are generally understood, the scattered X-rays can be steered, beam formed, or otherwise directed in a manner as desired or appropriate. By using the embodiment of the Compton scattered X-ray receiving assembly  151  as described with respect to  FIG. 6 , location of one or more scattering events occurring along one more applied X-rays  120  can be determined. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 7 , can be configured such that the Compton scattered X-ray receiving assembly  151  can be steered or directed in a plane perpendicular to that of the which the Compton scattered X-ray receiving assembly can sense the position of the scattering event. For example, the paths of the applied X-rays  120  as shown in  FIG. 2  are extending in a direction substantially perpendicular to the paper, while in  FIGS. 1 ,  3 - 6 , etc. the path of the applied X-ray  120  extend substantially within the plane of the paper. Certain ones of the scattering event detection, imaging, visualizing, and/or information providing mechanisms, as described above, may utilize such exemplary mechanisms to determine the position of the scattering event as: subtraction or combination, deconvolution, transforms, time of flight, scattering angle, loss of energy level of the X-ray photons of the scattering X-rays, geometric scattering computation, collimator, other derivatives, etc., and other locations through this disclosure. Each Compton scattered X-ray receiving assembly  151  as described with respect to  FIG. 7  includes a scanning shield portion  178 , which can be configured to limit light passing to that within certain angular ranges. More specifically, provided that there are an array, or a number of, the applied X-rays  120 , then the scanning shield portion  178  can limit passage of only one or a number of applied X-rays  120  at any one time period. Certain embodiments of the scanning shield portion  178  and/or the emitter portion(s)  150  can be dynamic, such as being rotatable; or alternately limit passage of only one or certain applied X-rays  120  continuously if the scanning shield portion  178  and the emitter portion(s)  150  are fixed or static. 
     As such, certain embodiments of the at least one slit collimator  172 , as described with respect to  FIG. 6 , can be viewed as limiting scattered X-rays  122  scattered from the applied X-ray  120 , and passing to the Compton scattered X-ray receiving assembly  151  in a directional substantially parallel to an axial direction of the applied X-ray  120 . By comparison, certain embodiments of the scanning shield portion  178 , as described with respect to  FIG. 7 , can be viewed as limiting scattered X-rays  122  which have been scattered from the applied X-ray  120 , and passing to the Compton scattered X-ray receiving assembly  151 , in a directional substantially perpendicular to an axial direction of the applied X-ray  120 . Both the scanning shield portion  178  as described with respect to  FIG. 7 , and the slit collimator  172  as described with respect to  FIG. 6 , can be viewed as embodiments of collimators, since they both limit passage of the scattered X-rays from scattering events that are situated within an angular range to the Compton scattered X-ray receiving assembly  151 . In addition, the material forming the housing material (as compared to the slits which may be air, or some X-ray transmissive material) of the scanning shield portion  178  and the slit collimator  172  should limit passage of X-rays there through, such as to limit screened X-rays from being applied to the Compton scattered X-ray receiving assembly  151 . 
     Within this disclosure, both the scanning shield portion  178  and the slit collimator  172  are intended to be illustrative in nature, but not limiting in scope. It is envisioned that certain processes as performed by either the scanning shield portion  178  and/or the slit collimator  172  could also be configured as a lens, a filter, a beamformer, or other electromagnetic or X-ray type mechanism, etc. As such, certain embodiments of the scanning shield portion  178  could limit passage of the scattered X-rays being applied to the Compton scattered X-ray receiving assembly  151  to within a range of angles, etc. 
     It is generally understood that with certain electromagnetic, optical, and/or X-ray technologies, certain operations can be performed utilizing two or more devices and/or their associated technique(s). Such devices, or technique, are often considered as equivalents, each of which is able to perform the desired function, operation, or technique. As such, certain embodiments of the collimator  172 , scanning shield portion  178 , etc. can be performed either by the device as described herein, or other generally known electromagnetic, optical, or X-ray equivalent devices and/or modifications thereof. Such generally equivalent devices are known by those skilled in the art can be utilized, and are intended to remain within the scope of the present disclosure. 
     This disclosure thereby illustrates a number of exemplary mechanisms (and associated techniques of certain embodiments of the Compton scattered X-ray receiving assembly  151 ) which can geometrically, computationally, or otherwise derive position of the scattering events within some matter. Such deriving the positions of the scattering events can be based at least in part on characteristics of at least some scattered X-rays  122  (while assuming a static or predictable applied X-ray). 
     Considering the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIG. 10 , the at least one emitter portion  150  (as described with respect to  FIG. 1 ) can at least partially utilize the applied X-ray  120  having its energy level that can be used to detect a position of the scattering event. Certain embodiments of the at least one emitter portion  150  can direct the applied X-ray  120  as to contact a contributing X-ray, beam, or other electromagnetic radiation beam  590  (which may include, but is not limited to, another applied X-ray having a prescribed energy level) as described with respect to  FIG. 10 . Such a contributing X-ray can alter the intensity of the applied X-ray by allowing the applied X-ray  120  to interfere (e.g., constructively or otherwise) with the contributing X-ray, beam, or other electromagnetic radiation beam  590 , to at least partially form in identifiable intersection point  592 . As evidenced by the enhanced scattered X-ray  122  that can be selectively viewed by certain embodiments of the Compton scattered X-ray receiving assembly  151 , the enhanced scattered X-ray will have an improved illumination corresponding to the increased energy level, as compared with the corresponding scattered X-ray resulting either from either applied X-ray  120  alone, or alternately the contributing X-ray, beam, or other electromagnetic radiation beam  590  alone. 
     Additionally, crossing or merging the applied X-ray  120  as to contact a contributing X-ray, beam, or other electromagnetic radiation beam  590  can enhance the probability of the scattering event  152  occurring within the matter of the at least a portion of the individual within the point of intersection  592 . Increasing the probability of the scattering event can thereupon improve the visualizing, imaging, or information providing associated with the location of the scattering event  152 . Within this embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , the point of intersection  592  can thereby correspond to the location of the scattering event  152 . The enhanced illumination resulting from the point of intersection  592  can be filtered, amplified, and/or otherwise processed as to further ease in display, visualization, information providing, imaging, etc. A conventional gamma knife (as generally understood in the medical technologies) can represent a cutting or destructing tool by which multiple gamma rays intersect as to provide a region of increased or combined energy, which can thereupon be detected in the form of a stronger applied X-ray  122 , as described in this disclosure. 
       FIG. 11 , for example, illustrates an embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be used for spatially confined imaging in which the output from the scattering event  152 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  are X-ray associated with a collimator  172  or  178 , as described with respect to  FIG. 6  or  7  in this disclosure. As such, certain embodiments of the Compton scattered X-ray receiving assembly  151  will only be able to detect scattered X-rays scattering from scattering events  152  that are within a spatially confined region. As such, certain embodiments of the emitter portion  150  can be configured as pencil beams, fan beams, flooding beams, or as having other beam configurations. However, each applied X-ray provided by the emitter portion  150  could be directed within the spatially confined imaging region (of the scattering event) such as to illuminate that region sufficiently such that the scattered X-ray can be detected by the associated Compton scattered X-ray receiving assembly  151 . 
     For the combination of any of the one or more emitter portion  150  and any of the Compton scattered X-ray receiving assemblies  151  as described in this disclosure, a variety of scattered X-ray, applied X-ray, matter, and other parameters can be determined that can be stored in a database, etc., and thereupon be used to derive the location of the position of the scattering events  152 ′, and/or  152 ″, etc. along the applied X-ray path  120 ′ as described with respect to  FIG. 5  utilizing known geometric, material, X-ray, and other calculations. Since certain scattering of the applied X-ray photons  120  can be intermitted at certain ones of the position of the scattering events  152 ′,  152 ″, etc.; the visualization, imaging, or information providing parameters at the various positions of the scattering events can be intermittently obtained. As the X-ray photons of the applied X-rays scatter at each position of the scattering event based on Compton scattered X-ray, the visualization, imaging, or information providing parameters of each position of the scattering event  152 ′, and/or  152 ″, such as can be used to image there from, and can be determined. 
     The relative angle and/or position of the applied X-rays  120  can thereby be determined, derived, or computed based at least in part on the angle of the one or more emitter portion from each particular scattering event location  152 ′,  152 ″, etc. The frequency (or the energy level which corresponds to the frequency) of the X-ray photons forming the applied X-rays  120  can be determined based at least in part on the known or determined input frequency to the one or more emitter portion  150  (or the measured output). The angle of the scattered X-ray photons being received by the one or more Compton scattered X-ray receiving assemblies  151  can be determined based at least in part on the original path of the applied X-ray, as well as the scattered frequency of at least some of the X-ray photons of the scattered X-rays. 
     Certain visualization, imaging, or information providing techniques can rely of generation of image information or visualization information that can represent data or other form of information. Such data, text, information, etc. can be stored or maintained in a database storage, processed using understood image processing techniques, etc., such as described with respect to certain embodiments of the visualization, imaging, or information providing controller  97  as described with respect to  FIG. 1 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information at least partially by making 2-D scans from different “vantage points” outside the body, detecting the time-integrated X-ray return signal from each 2-D X-ray/vantage-point combination, and doing a tomography-like reconstruction of such as depth-related 3-D structure as described with respect to  FIGS. 12   a ,  12   b , and  13 . 
       FIGS. 12   a  and  12   b  illustrate two views of one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  which can be configured to just and/or controlled in imaging perspective by which the angle of the scattered X-ray changes from  122   a ,  122   b ,  122   c , as indicated by an arrow  127 , can be used to image the portion of the individual. During the visualization, imaging, and/or information providing, as described with respect to  FIG. 12   a , a variety of image information (similar in certain ways to conventional tumble graphic imaging or volumetric imaging techniques) can be derived. However, there can also be a considerable amount of information that can be determined based upon the scattering of the applied X-rays from a certain direction, or a limited range of directions. For example, a depth of the tissue aberration (or other tomography-type feature)  128  is largely uncertain during the visualization, imaging, or information providing as described with respect to  FIG. 12   a  as a result of the relative direction in which the Compton scattered X-ray receiving assembly  151  receives the scattered X-rays. 
     As the angle of the scattered X-ray continues to increases through an angle, as described with respect to  FIG. 12   b  as  122   d ,  122   e , and  122   f , the depth determination or extent of the feature  128  (using volumetric, tomographic, or other such techniques) can be improved as the angle of the scattered X-ray continued to increase. As such, the depth can be more readily and accurately be determined as the angle of the scattered X-ray increases from perpendicular. Such dimensions, extends, etc. of the features can be determined to more fully and accurately map the visualization, image, or provided information relative to the matter of the at least a portion of the individual, such as: tissue, tissue aberrations, organs, edge features, bones, constructs, inserts, bony portions, fluid or blood vessels, reservoirs, pooling, etc. 
     While the imaging perspective described with respect to  FIGS. 12   a  and  12   b  can be used to adjust or control the angle of the scattered X-rays relative to matter of the least to portion of the individual, there can be a variety of other imaging perspectives that can be similarly adjusted, controlled, and/or otherwise utilized. For instance, the at least in the portion of the individual could be moved relative to the applied X-ray and/or the scattered X-ray. As the field of view of the visualization, imaging, or information provided is zoomed, focused, filtered, transformed, or otherwise modified to provide other “new” or “modified” (e.g., and/or adjusted or controlled) information, such new or modified information can be added to the enhanced the model, visualization, image, or information; such new or modified information can be compared with the original information to provide a more accurate or detailed model, visualization, image, or information. The techniques used for adjustment and/or control of the visualization, imaging, or information providing, certain ones of which are described relative to  FIGS. 42 through 45 , can be used to improve a quality of visualization, imaging, or information provided based on a variety of vantage points, and can be utilized for tomography or volumetric-type imaging. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured to provide tomography visualization, imaging, or information providing. The tomography provided would be expected to be similar to the tomography provided by other imaging mopdalities such as CAT scans, PET scans, and MRI, with the exception that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider would image matter to the prescribed imaging depth. Other embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , by comparison, would be expected to image through the matter of the at least some matter of the at least the portion of the individual. Additionally, the embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can generally utilize Compton scattering, as compared to transmissive X-rays as with CAT scans, transmissive positrons as with PET scans, and magnetic fields as with MRI. Each imaging modality would therefore be expected to visualize, image, of provide information somewhat differently with potentially somewhat different output (either with or without the use of contrast agents). 
       FIG. 13  show a flowchart  1300  of one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be configured to provide a tomography-type and/or volumetric visualization, image, or information in a manner that includes illustrative, but not limiting, processes  1302 ,  1304 ,  1306 , and/or  1308 . Process  1302  can include, but is not limited to, visualizing, imaging, or deriving at least a first set of visualizations, images, or information. For example, certain visualization, image, or provided information (e.g., relatively crude in certain instances) can be obtained using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure. Process  1304  can include, but is not limited to, controlling or adjusting the Compton scattered X-ray visualizer, imager, or information provider  100  such as to visualize, image, or obtain “additional” information. Process  1306  can include, but is not limited to, operating the Compton scattered X-ray visualizer, imager, or information provider  100  to capture, or otherwise obtain, the new information, such as to allow imaging from a modified vantage point. Process  1308  can include, but is not limited to, obtaining a more detailed or final visualization, image, or information by tomographically or volumetrically integrating the additional information. As such, viewing certain regions from different perspectives, such as to limit unknowns and uncertainties in the visualization, imaging, or provided information as the tomogreaphic-type embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  change some aspect (e.g., energy level, direction, depth, etc) in a manner as to improve the quality of the visualizing, imaging, or information providing. 
     Certain scintillation, time of flight, energy loss, and image combination type embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can generally provide their final-quality visualization, image, or provided information based on processing of each interaction of the at least one emitter portion  150  and its associated at least onhe Compton scattered X-ray receiving assembly  151 . By comparison, certain tomographic or volumetric embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  have a considerable number of unknowns following each interaction of the at least one emitter portion  150  and its associated at least onhe Compton scattered X-ray receiving assembly  151 , wherein such unknowns are generally reduced or limited using tomographic or volumetric techniques, in a similar manner as with conventional tomography, as generally understood in the medical imaging technologies. 
     Certain tomography or volumetric aspects of certain embodiments (or output) of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be quite similar in processing characteristics to those of conventional tomography imagers, such as CAT scans, PET scans, etc. (such that they can result from generating a number of two-dimensional slices). The slices are typically, but not necessarily, planar. The slices can thereupon be combined to allow information of any three-dimensional volumetric image in a similar manner as with conventional CAT scans, MRIs, etc. Depending upon the desired configuration, a variety of shapes, Compton or other configurations of slices can be generated. Within this disclosure, volumetric imaging may, depending upon context, be considered as including tomography. A description of conventional tomography or volumetric imaging devices, etc., such as may be utilized for conventional medical visualizing, imaging, or information providing, are described, for example, in X-ray 13 of “The Essential Physics of Medical Imaging, Second Edition”, J. T. Bushburg, et al., Lippincott Williams and Wilkins, 2002 (incorporated by reference herein in its entirety). Such conventional tomography devices are commercially available and is not described in greater detail. 
     Is the understood that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may rely upon the adjustment and/or control to affect imaging of new matter of new directions, locations, positions, energy levels, etc. Such adjustment or control may be useful for tomography-type Compton scattered X-ray visualization, imaging, or information providing. 
     Certain embodiments of the deconvolution and/or tomography processes necessary to perform such operations can be considered as computationally similar to those used in normal X-ray CT scans, except that scattered instead of transmitted X-rays are detected (instead of the X-rays being transmitted through the individual as is the case with conventional CT scans as compared with X-rays undergoing Compton scattering as described in this disclosure). 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information at least partially by use of an angle-collimated X-ray detector such that the intersection of the illuminating beam and detector sensitivity direction can define a unique 3-D voxel as described with respect to  FIG. 5 . Such angle-collimated X-ray detectors can be used to derive visualization, imaging, or information providing information in the one or more Compton scattered X-ray receiving assemblies  151 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information at least partially by combinations of the embodiments described elsewhere in this disclosure, that allows visualization, imaging, or information providing at higher resolution and/or higher contrast information from the subcutaneous bodily structures. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can control the depth to which it can image based, at least in part, on photons energy level of the applied X-ray as applied to the matter of the at least the portion of the individual. The greater the energy level of the photons of the applied X-rays (and correspondingly the lesser the frequency of the photons of the applied X-ray  120 ), generally the greater depth a larger percentage of the applied X-ray can travel into the matter of the at least the portion of the individual, scatter, and return to effect Compton scattered X-ray visualization, imaging, or information providing. As such, generally, a larger number of, or percentage of, X-ray photons having greater energy levels (and therefore correspondingly lower frequencies) can generally visualize, image, and/or information provide down to a greater at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth than X-ray photons having a generally lower energy level (and correspondingly higher frequencies). This generalization assumes consistency of such factors as angle or position of applied X-rays, materials being imaged, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure with respect to  FIG. 14 , can facilitate Compton scattered X-ray visualization, imaging, or information providing of a region of the scattering events extending from at least a surface  168 . 
     These embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be particularly useful for Compton scattered X-ray visualization, imaging, or information providing for the at least the portion of the individual near the surface  168  of the individual (the surface may be underneath and at least partially internal surface or at least partially external surface). For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , that can image from a surface to within the at least one depth range to the at least one prescribed depth, may be suitable for such Compton scattered X-ray visualization, imaging, or information providing even without complex image processing. Such visualization, imaging, or information providing from different depths may not interfere with each other provided a relatively homogeneous material across the visualization, imaging, or information providing depth range. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, or information provide one and relatively non-homogeneous material across the at least one visualization, imaging, or information providing depth range provided suitable processing capability. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, or provide information relating to at least partially internal and/or at least partially external matter of the at least the portion of the individual utilizing a variety of Compton scattered X-ray visualization, imaging, or information providing techniques. Such visualization, imaging, or information providing can be configured to provide for, for example: examinations, testing of cancer, sicknesses, injuries, tissue aberrations, etc. (such cancers and/or tumors can include, but are not limited to, breast cancer, lung cancer, prostate cancer, bladder cancer, cervical cancer, etc.); as well as both internal or external visualizing, imaging, or information providing aberrations of certain matter of the at least the portion of the individual (such as tissue, bone, dental, etc. or a combination); Compton scattered X-ray visualization, imaging, or information providing lumen matter and matter examinations; Compton scattered X-ray visualization, imaging, or information providing edges, discontinuities, or matter inconsistencies or aberrations of organs, tissue, or other matter; Compton scattered X-ray visualization, imaging, or information allowing a variety of heart examination and/or treatments, heart valve structure, operation examination and/or treatments, brain examination and/or treatment, lung examination, liver examination, other organ, matter, or tissue examination and/or treatments etc. Within this disclosure, the term “depth” visualizing, imaging, or information providing can include, but is not limited to, depth visualizing, imaging, or information providing at least one volume of matter beneath the surface  168  of the at least the portion of the individual, perhaps including the surface  168  of the at least the portion of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to detect specific elements, or sets, combinations, alloys, and/or mixtures of specific elements, such as may be used to obtain signatures of pathological state or tissue identity. While iron and calcium are mentioned in this disclosure as examples of elements that may be included in matter which can be used to enhance visualizations, imaging, and/or information providing; it may also be desirable or useful to detect other elements or sets of elements. Depending on context, X-ray scattering signatures of tissue (which may be considered to be one embodiment of visualization, imaging, or information providing information), may be very helpful for a variety of diagnosis or examination purposes, for example. 
     Another example of an element, which could be detected by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , is zinc. Zinc can be used as a naturally-occurring indicator of certain types of pathological brain tissue. For example, the elevated presence of zinc in the brain can be used to identify epileptic areas in hippocampus. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to detect particular elements, matter, combinations of matter, materials, metal, alloys, fluids, bones, etc., and as such may be particularly useful for visualization, imaging, or information providing for certain applications. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be controllable and/or adjustable such as to allow setting or adjusting for particular visualization, imaging, or information providing applications. 
     Certain embodiments of such Compton scattered X-ray visualization, imaging, or information providing from the surface  168  may be performed from within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth. Certain of the Compton scattered X-rays returning to the Compton scattered X-ray receiving assembly  151 , that scatter at scattering events from matter from different ones of the at least one substantial scattering range to the at least one scattering depth, may overlap and potentially interfere with scattered X-rays that have a contributed X-rays from different scattering events. Such clarification between interfering scattered X-rays resulting from different scattering events at different depths, and/or positions, etc., can limit confusion among image information obtained from different scattering events at varying depths. 
     Assuming a relatively narrow visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth based at least partially on scattering from scattering events. The overlap of X-rays Compton scattered from different depths can be considered as originating from a single one of the at least one substantial scattering range to the at least one scattering depth, assuming the material is substantially homogenous across the range of depths. The overlapped X-rays can thereupon be processed or treated as originating from the same location. For example, Compton scattered X-ray visualization, imaging, or information providing of the skin, and/or some other relatively homogeneous matter, of a person may appear consistent, even if the Compton scattered X-rays scattering from within the at least one substantially scattered depth range to the at least one prescribed substantially scattering depth. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, or provide information based at least partially on scattered X-rays being scattered the slightly overlapped depths of scattering events, and can thereby reduce quality or uniformity of imaging or visualization. For example, consider the Compton scattered X-rays could be expected to be Compton scattered, down to similar scattering depths, within similar type matter within the person, assuming substantially homogeneous or consistent matter down to the imaging depth. Certain types of Compton scattered X-ray visualization, imaging, or information providing can be performed as scanning, such as to screen for, or detect, aberrations of the matter (e.g., skin) such as cancers, lesions, tumors, moles, cuts, abrasions, etc. Certain embodiments of the Compton scattered X-ray receiving assembly, which can be used to visualize, image, or provide information relating to a considerable variety of matter, such as regents made up of relatively thin matter that are selected to increase the homogeneity of the region. By selecting or using the relatively thin image region, the matter&#39;s homogeneity thereby generally increases to thereby provide improved visualization, imaging, or information providing. By using relatively thin image regions, which are therefore more homogeneous, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may utilize such devices as scintillators (and/or fluoroscopes, certain of which can include scintillators) which can directly convert scattered X-rays into viewable and/or visible light, as described in this disclosure. Within this disclosure, “viewable” light can, depending on context, be intended to include, but is not limited to, visible light such as is recognized as being viewable by most sighted humans, as well as at least certain infra-red and ultra-violet light. 
     Within this disclosure, such conversion of X-ray photons by scintillators into viewable and/or visible light that may be viewed (directly or by subsequent processing) by certain users of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . By comparison, certain embodiments of the Compton scattered X-ray receiving assembly  151  may include a photodiode or other photodetector operably associated with the output of the scintillator (not shown, and considered as a portion of the scintillator) which can output to certain portions of the Compton scattered X-ray receiving assembly. As such, certain scintillator-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide viewable and/or visible light directly to a user, or alternately output viewable and/or visible light that can be further analyzed, amplified, filtered, or otherwise processed such that could be viewed by the user following the multiple steps such as by a machine, machine-based processor, optical processing device, etc. Certain scintillators, for example, could be operably coupled to photodiodes, whose outputs can be further analyzed. 
     Certain scintillator embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  being applied to certain relatively thin organisms, plants, etc. may also visualize, image, or provide information about the thickness of at least some matter of the at least certain portions of the individual using such techniques. Certain such scintillator (and/or fluoroscope) embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be operationally simpler, and therefore involve relatively little processing as compared with other visualization, imaging, or information providing techniques by other (more processor-complex) embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . The scintillator embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can create images based, at least in part, on the scattered X-rays  122  received by the Compton scattered X-ray receiving assembly  151 ; since the Compton scattered X-rays being produced by the former are being converted directly into viewable or visible light using scintillators (and/or fluoroscope-based technology). 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure with respect to  FIGS. 15 and 16 , can facilitate Compton scattered X-ray visualization, imaging, or information providing between a first one of the at least one visualization, imaging, or information providing depth range to the first one of the at least one prescribed visualization, imaging, or information providing depth from the surface  168 . Such visualizing, imaging, or providing information can occur either from an internal or external surface of the portion of the individual (or the first one of the at least one visualization, imaging, or information providing depth range to the first one of the at least one prescribed visualization, imaging, or information providing depth from the surface  168 ) to a second one of the at least one visualization, imaging, or information providing depth range to a second one of the at least one prescribed visualization, imaging, or information providing depth from the surface. 
     Certain of such Compton scattered X-ray visualization, imaging, or information providing techniques can be obtained at least partially by combination (e.g., image differentiation, image subtraction, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, time of flight calculation, or other such computation or image processing techniques). With such combination of images, etc., multiple depth visualizations or images can be obtained, in the form of depth visualization or image information, from Compton scattered X-ray visualization, imaging, or information providing from the surface  168  down to multiple different depths  169 ,  170 , thereby imaging through a depth  172 . 
     Certain occurrences of the depth visualizations, images, and/or provided information can thereupon be obtained from the shallower depth visualizations, images, and/or provided information value using image combining (such as by using image subtraction, image differentiation, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing or computational techniques), from between multiple depth visualizations, images, and/or provided information values. To depth-image a relatively thick portion of the individual (e.g., a slice that is thicker than can be depth imaged by itself with desired resolution, image quality, etc.), a number of relatively thin image slices can be imaged, and the number of images can thereupon be added, summed, or otherwise combined using a variety of appropriate image processing techniques. 
     As described in this disclosure, the visualization, imaging, or information providing of slices can be performed by successive image combination, by which the information, data, value, etc. of the shallower image can be combined, subtracted, or otherwise transformed out from that of the thicker image for each successive image slice, to obtain image information of the particular image slice. 
     Such techniques can also be utilized by certain image combining processes (e.g., image subtraction, image differentiation, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, time of flight techniques; scintillator [or fluoroscope] techniques, or other Compton-based techniques). The image slices can at least partially involve combining relatively thick portions of the individual, and can thereupon be digitally, analog, or otherwise combined using combining image processing techniques, and can be clarified such as to limit distorting aspects such as opaque X-ray matter, noise, etc, such as involving deconvolution, transforms, etc. Certain of the visualizations, images, and/or information can be maintained to form a model, which can be relied on for visualization, imaging, or information providing purposes. Alternately, a two-dimensional image slice having some thickness and either a substantially planar or curvilinear surface (simple curve, complex curve, or other) can be visualized, imaged, or have information provided within the at least the portion of the individual at a location nearby, or away from, the surface of the at least the portion of the individual. For example, certain examples of visualization, imaging, or providing information can occur with the at least one emitter being positioned adjacent the skin, within lumens, etc. 
     Alternately, time of the flight computations can be used to derive visualization, imaging, or information providing information, as described in this disclosure. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize or image a volume or portion extending between two of the at least one visualization, imaging, or information providing depth ranges from the surface  168  can utilize time of flight computations (such as described with respect to  FIG. 17 ). Certain time of flight computations can operate at least partially by determining a total distance from the emitter portion  150 , to the particular scattering event of the at least the portion of the individual, and thereupon continue to the Compton scattered X-ray receiving assembly  151 . Such distance can be determined, for example, by measuring the duration for X-rays to travel that distance. The distance can thereby be determined at least partially based on the combined temporal duration (time) of the travel by the applied X-ray  120  and/or the scattered X-ray  122 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  of  FIG. 17  can include a time of flight calculator  160  (which can be included in the visualization, imaging, or information providing controller  97  of  FIG. 1 ), which can derive the time of flight duration(s), and thereupon compute the total time of flight distance(s). 
     Certain embodiments of time of flight computation such as can utilize the time of flight calculator  160 , as described with respect to  FIG. 17 , can involve generation of relatively brief pulses of the applied X-ray (e.g., X-ray photon radiation), which are directed by the at least one emitter portion  150  towards the imaged region of the at least the portion of the individual. Thereupon, the X-rays forming the pulses or bursts of applied X-rays can be Compton scattered within the matter of the at least the portion of the individual at the scattering event, such as can be detected by the at least one Compton scattered X-ray receiving assembly  151  following scattering of the brief pulse (also considered a form of time modulation). Time of flight calculations can be derived based, at least partially, on the time required for the applied X-rays to travel to and scatter at the scattering event (within the matter of the at least the portion of the individual), and thereupon have the scattered X-rays travel to the at least one Compton scattered X-ray receiving assembly  151 . Considering the total distance between the point of Compton scattered X-ray at the scattering event and the Compton scattered X-ray receiving assembly, and thereupon the angle of scattering and scattering event through which the X-rays travel through the at least the portion of the individual. The location of the scattering event within the matter of the at least a portion of the individual can thereupon be determined relying on calculations based on the speed of X-rays, their direction traveled, and thereupon their distance traveled (the speed of X-rays correspond to the speed to light). 
     The total distance from the emitter portion  150 , to the location of the scattering event, and thereupon to the Compton scattered X-ray receiving assembly  151 , can thereby be used to derive the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth at least partially using time of flight calculations. With time of flight calculations, precision in the detected timing and measured distance is important in accurately determining the location of scattering within the matter. Therefore, certain embodiments of the detector portions of the Compton scattered X-ray receiving assembly and/or emitter portions, as described with respect to  FIG. 17 , could have at least low picosecond range detection operational duration to provide suitable accuracy. Such picosecond range detection operational duration to provide suitable accuracy can be performed using, for example, certain streak cameras, pixellated streak cameras, an avalanche detector, CCD, or other detector embodiments of the Compton scattered X-ray receiving assembly  151 . Other embodiments of the detector portions could operate with considerably longer signal detection duration rate while perhaps accepting reduced quality or resolution in visualization, imaging, or information providing. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize a variety of controllers, computers, etc. (considered as a portion of the visualization, imaging, or information providing controller  97 ) as certain users such as to provide a variety of automation and/or enhanced reliably of operation or analysis. As such, with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , a variety of human or automated users can visualize, image, and/or provide information relating to the subsurface of the at least the portion of the individual  82  at certain typically controllable depths. The mechanism for Compton-type scattering are generally understood by those skilled with X-ray technology, and will not be described in greater detail except where suited to this particular disclosure. 
     With individuals such as humans and/or animals, for example, the external surface  168  can include such surfaces as skin, mucous membranes, and other such external surfaces etc. Certain individuals such as plants or organisms (living in the environment such as outside, living in humans, animals, plants, or other organisms, and/or human-designed or human created) can have at least one external surface  168  that may come in contact with the external environment from which much of the potential visualization, imaging, or information providing could be performed. Examples of the external surface may include the outer layer of a leaf, a trunk, a stalk, a fruit, a root portion, a vegetables, etc. It may not be necessary, in those embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , that are applied within the matter of the individual (such as via incision, or other breach of the surface), to visualize, image, and/or provide information at least partially through the surface. 
     Certain individuals, such as organisms, plants, or portions thereof, can be visualized, imaged, or have information provided using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  for such purposes as to determine health, internal structure, insect infestation, contamination, illness, etc. Certain types of individuals such as fruits, roots, or vegetables as produced by plants can be visualized, imaged, or have information provided using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as to determine freshness of the item, suitability of the item, insect infestation, disease, contamination, inconsistency from desired state, etc. A forestry store or market (which may commercially sell certain meats, vegetables, fruits, plants, etc., for example) may utilize certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  such as to visualize, image, and/or provide information relating to meats, plants, vegetables, fruits, etc. to determine their health, condition, etc. Such determination of the condition can be applied either prior to purchase, following storage for some duration, or prior to selling, etc. such visualization, imaging, or information providing of plants, organisms, troops, roots, etc. can be based, at least in part, and changing X-ray scattering characteristics as the matter rots, disintegrates, melts, distorts, ages, or otherwise changes. 
     With such individuals as humans and/or animals, the term “internal” can pertain to those locations accessible through normally open openings (e.g., mouth, ears, nose, various lumens, blood vessels, urethra, anal, etc.) and/or normally closed openings, such as may be accessed via an incision as described in this disclosure. The interior of such individuals as organisms, cells, bacteria, viruses, etc. can be accessed through normally closed openings such as incisions, pipettes, probes, tools, tactile feedback devices, cutters, displays, etc. As such, the term “surface”, whether situated at least partially internally and/or at least partially externally relative to the at least the portion of the individual, should relate to, and/or be considered relative to, and based on, the particular aspects, conditions, and/or particulars of the at least the portion of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide position determination, control, and/or adjustment of certain of the at least one emitter portions  150  and/or the at least one detector portions  152  (and/or the at least one Compton scattered X-ray receiving assembly  151 ). Such adjustment and/or control of the portions or entirety of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used to control and/or adjust the amount of matter through which the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information, such as when Compton scattered X-ray visualization, imaging, or information providing (to within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth). Such control and/or adjustment is typically characterized by the energy level and/or frequency of the X-ray photons. 
     For example, assume that a particular Compton scattered X-ray visualizer, imager, or information provider  100  is configured (e.g., based on X-ray photon energy and/or frequency) to visualize, image, and/or provide information at the at least one controllable and/or adjustable prescribed visualization, imaging, or information providing depth. If the at least one emitter portion  150  can be arranged to direct the applied X-ray  122  substantially perpendicular to the surface  168  of the at least the portion of the individual, the visualization, imaging, or information providing could occur within the at least one prescribed visualization, imaging, or information providing depth of, for example, 5 mm. However, as the angle of the applied X-rays by the emitter portion to the surface  168  of the matter changes from perpendicular to some slant from a surface of the at least the portion of the individual, such as illustrated in  FIGS. 16 to 17 , the at least one prescribed visualization, imaging, or information providing depth also changes. The at least one prescribed visualization, imaging, or information providing depth corresponds to the maximum depth which the X-rays can pass to, scatter at, and return from during the Compton scattered X-ray visualization, imaging, or information providing. Therefore, as the angle of the X-rays applied by the emitter portion to the surface  168  of the at least some matter of the at least the portion of the individual changes (e.g., from perpendicular to some angle), the effective perpendicular depth visualizing, imaging, or information providing could change, which typically changes as a cosine function of the change of angle. 
     With almost all types of individuals, most surfaces  168  are not completely planar. Consider that people, animals, organisms, and plants are not typically flat, but instead have some degree of curvature over our surfaces. For the purpose of this disclosure, such visualization, imaging, or information providing concepts can be explained and more easily modeled assuming a planar initial contact surface, which may become closer to true as the depth imaged or visualized region becomes incrementally smaller. 
     Within this disclosure, “Compton scattered X-ray visualization, imaging, or information providing”, as may therefore be performed within some set distance from the surface  168  at which X-ray based electromagnetic radiation from the Compton scattered X-ray visualizer, imager, or information provider  100  is being emitted and Compton scattered, and can thereupon be detected. Certain aspects of such Compton scattered X-ray visualization, imaging, or information providing may rely on the configuration and/or operation respective emitter portions and/or detector portions that can respectively apply X-rays proximate to, and/or receive X-rays from, the surface  168  of the at least the portion of the individual. 
     The matter of the at least the portion of the individual which can be visualized, imaged, or have information provided using a variety of embodiments and/or configurations of the Compton scattered X-ray visualizer, imager, or information provider  100 , can vary. For instance, for Compton scattered X-ray visualization, imaging, or information providing humans or animals, the soft matter that can be visualized, imaged, or have information provided can include but is not limited to: soft tissue, fluid (blood, spinal, lymph, etc.) bone portions interspersed among tissue, tissue forming organs, muscles, fat, flesh, etc. Additionally, relatively hard matter such as: bones, bone portions, joints, spine portions, teeth, etc. can be visualized, imaged, or have information provided using certain configurations or embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . As such, the interior bones, teeth, etc. can be depth imaged to provide a considerable amount of internal visualization, imaging, or information providing. As such, the particulars of the at least some matter can have some effect on the visualizing, imaging, or information providing. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can additionally visualize, image, and/or provide information relating to such matter can be associated with, or positioned in or nearby the at least the portion of the individual as plastic, metal, implants, pins, constructs, fillings, orthopedic braces, dental braces, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be either stand-alone devices, or provide input into the at least the portion of the individual such as a tool, implant, tactile feedback providers, injecting device, probe, cutter, drill, separator, ablator, Bovie electrocautery device, material adder, material remover, etc. Certain portions of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can pertain to visualizing, imaging, or information providing within the medical areas, orthopedic areas, research areas, dental areas, orthodontia areas, veterinarian areas, livestock areas, wild animal or aquatic animal areas, etc. 
     Compton scattered X-ray visualization, imaging, or information providing of such individuals as plants or organisms can involve depth visualizing, imaging, or information providing at least some of the various particular components or structure of the plant or organism. Such Compton scattered X-ray visualization, imaging, or information providing of plants, organisms, etc. can be for research, commercial, medical, veterinarian, dental, or other purposes. For instance, certain organisms being visualized, imaged, or have information provided can within a human, animal, or other host, can be distinct, or can be at least partially integrated in human, plant, organism, animal, etc. 
     There may be particular aspects of particular type of Compton scattered X-ray visualization, imaging, or information providing, as can be performed by particular embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be particularly useful in Compton scattered X-ray visualization, imaging, or information providing a region within the at least the portion of the individual that is physically separated from the location where the applied X-rays  120  initially pass through the surface. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may have to image through considerable matter, tissue, etc. that may not be desired to be included in the visualization, imaging, or information providing, such as by using image combining (e.g., image subtraction, time of flight Compton scattered X-ray depth visualization, or other technique such as by using image subtraction, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques), and/or other imaging, or information providing, techniques as described in this disclosure; the depth visualizing or imaging effects of such matter that is not desired to be visualized, imaged, or have information provided can be computationally limited. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured or operated to most effectively image the matter of the at least the portion of the individual situated nearby the external or internal surface  168  (e.g., via skin or other internal or external surface, or alternately through an incision, cut, etc.) of the at least the portion of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are described in this disclosure as having their energy level and/or frequency of the applied X-rays that can be controlled and/or adjusted. The term controllable can, depending on context, indicate the ability of the user and/or other entity to control the depth, and/or range of depths, at which the Compton scattered X-ray visualizer, imager, or information provider  100 , can image through the matter of the at least the portion of the individual. Such control can be based at least in part on controlling the energy level and/or frequency of at least some applied X-rays  120 . By comparison, the term adjustable can, depending on context, indicate that some adjustment can be made to the depth at which the Compton scattered X-ray visualizer, imager, or information provider  100  visualizes, images, or provides information into the matter of the at least the portion of the individual. Such adjustment can be based, at least in part, on controlling the energy level and/or frequency of at least some applied X-rays  120 . Such control or adjustment of depth, or range of depths, can be made during initial and/or subsequent depth visualizing, imaging, or information providing, and can be empirically determined or not. A variety of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be controllable and/or adjustable based at least in part on controlling the energy level and/or frequency of at least some applied X-rays  120 , as described in this disclosure; while other embodiments may not. 
     Certain embodiments of the visualization, imaging, or information providing controller  97 , of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can utilize a variety of software, hardware, firmware, depth visualizing or imaging technology, electronic and/or electric circuitry to facilitate the desired Compton scattered X-ray visualization, imaging, or information providing. A variety of the software, hardware, firmware, depth visualizing or imaging technology, electronic and/or electric circuitry is understood in the field of controllers, optical systems, electronics, and/or computers; and might be effectively performed by a variety of types of the visualization, imaging, or information providing controller  97 . For instance, certain embodiments of Compton scattered X-ray visualization, imaging, or information providing that can rely at least partially on visualization, imaging, or information providing image subtraction or combination, filtering, and/or processing, etc., as described in this disclosure, such as are particularly likely to involve software, hardware, firmware, and/or electronic to perform suitable image processing such as transforms, etc. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow transitioning or reconfiguration between different types of Compton scattered X-ray visualization, imaging, or information providing such as by operation selection, reprogramming, modification, replacement, or reconfiguration of the visualization, imaging, or information providing controller  97  (such as may control operation of the emitter portion  150  and/or the Compton scattered X-ray receiving assembly  151  of  FIG. 1 ). The operational or processing requirements of the visualization, imaging, or information providing controller  97  may be quite demanding, for certain applications. 
     There are a number of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be used to visualize, image, or provide information.  FIGS. 18 and 20 , for example, illustrate two respective exemplary but not limiting embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , each embodiment conforms generally to the description on this disclosure relating to the  FIG. 1  block diagram. Exemplary, but not limiting, logic pertaining to the respective  FIGS. 18 and 20  embodiments of the Compton scattered X-ray visualizer, imager, or information providers  100 , and can be applied to certain large flow charts as described respectively relative to  FIGS. 19 and 21 . 
     It is envisioned that one or more distinct components, or portions, of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , can be included in one or more separate or distinct Compton scattered X-ray visualizer, imager, or information providers  100  (such as described with respect to  FIG. 1 ) can be operationally combined or configured as desired. Such components or portions from the one or more separate or distinct Compton scattered X-ray visualizer, imager, or information providers  100  can interoperate, using known networking concepts. Each portion or component of the Compton scattered X-ray visualizer, imager, or information provider can thereby perform one or more distinct functions or operations associated with the Compton scattered X-ray visualizer, imager, or information provider. 
     As such, at least certain portions or components of different embodiments of one or more of the Compton scattered X-ray visualizer, imager, or information provider  100  can interface and/or interact with each other such as to transfer, transmit, and/or receive images, visualize, image, and/or provide information therebetween. Such transfer, transmission, and/or reception techniques can be provided in a manner utilizing techniques understood by those skilled in computing, hard-wired, wireless, networking, optical, communications, and other similar technologies. Such transmission, transferring, and/or receiving can be performed utilizing wireless, optical, wired based and/or other known technologies. 
     There can be a variety of, and embodiments of, devices and/or techniques which can be used by the at least one emitter portion  150 , that can generate the applied X-rays. For example, certain embodiments of the at least one emitter portion  150  of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize X-ray devices, tubes, etc. to generate X-rays. A variety of X-ray tubes may be used to generate X-rays for a variety of conventional X-ray devices and/or conventional fluoroscopy devices, such as are generally known and are commercially available. Conventional X-ray devices, tubes, etc., such as may be utilized for conventional medical visualizing, imaging, or information providing, are described, for example, in chapter 5 of “The Essential Physics of Medical Imaging, Second Edition”, J. T. Bushburg, et al., Lippincott Williams and Wilkins, 2002 (incorporated by reference herein in its entirety). The X-ray tubes, devices, etc. can, depending on context, be considered as those devices that can be configured to produce X-rays including X-ray photons of a particular energy level or range, frequency or range, power or range, etc. he the For conventional transmissive X-ray imaging, for example, the X-rays can pass through the at least the portion of the individual  82 . By comparison, those embodiments of the at least one emitter portion  150  of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information utilizing such Compton scattered X-ray mechanisms as Compton backscatting, Compton forward scattering, etc. of the applied X-ray in a manner that can rely on X-rays that have characteristics (frequency, energy level, power, etc. of the X-ray photons). 
     Certain external embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured such that the particular frequency or X-ray photon energy, or such other operational characteristic(s) of at least some of the X-ray photons included within the applied X-ray, can pertain to the depth of the Compton scattered X-ray visualization, imaging, or information providing. As such, the frequency or energy level of a number of X-ray photons included in the applied X-ray, if controlled or adjusted, can have the effect of controlling or adjusting the depth(s) of Compton scattered X-ray visualization, imaging, or information providing into the matter of the at least the portion of the individual  82 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information down to within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth, which range of depths can be at least partially adjusted and/or controlled. Such determination can be either at least partially empirically, empirically, such as by calculation, derivation, or determination. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can obtain the X-ray Compton scattered X-ray information in the form of information, data, depth visualizations, images, and/or provided information, etc. 
     The at least one substantially scattered depth range to the at least one prescribed substantially scattered depth distance from the surface  168  of the individual, such that the electromagnetic radiation of the applied X-ray passes into the at least the portion of the individual, scatters, and may therefore cause a reduction in the energy level of the X-ray upon scattering. The latter distance can thereby be controlled to effectively control the Compton scattered X-ray visualization, imaging, or information providing characteristics as per the former. Certain of the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth, which can vary along with varied surface configurations, roughness, material non-uniformities, etc. 
     By controlling the characteristics of the X-rays photons (e.g., frequency and/or energy level of the X-ray photons of the X-rays, intensity of the X-rays, angle of the X-rays, etc.), the perpendicular distance from the surface  168  of the at least the portion of the individual that the applied X-ray passes can be controlled and/or adjusted. Such control and/or adjusting of the energy level, frequency, direction, intensity, position, and/or other aspect or parameter of the applied X-rays can considerably limit the amount and type of matter of the at least the portion of the individual through which the X-rays may be applied. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be configured to emit the X-ray based electromagnetic radiation (of the applied X-ray or the scattered X-ray) at one or more selected organ(s) and/or matter, while limiting the application of the X-ray electromagnetic radiation to other organs, matter, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can control the angle at which it applies its X-ray photons to the surface  168  of the at least the portion of the individual. 
     Due to the uncertain health effects of application of X-rays on humans, other individuals, and/or users, it may be desirable, in many instances, to limit the amount of X-ray electromagnetic radiation applied to the at least the portion of the individual, and/or any nearby users, when using the Compton scattered X-ray visualizer, imager, or information provider  100 . Additionally, it would be expected to ease acceptance of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  by the appropriate regulatory agencies, in the amount of X-rays being applied to individuals and/or users (particularly human) could be limited considerably. As such, by the certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  be configured to image a relatively small portion of the individual using depth-imaging techniques (e.g., imaging scan in a small portion underneath, primarily imaging matter through a depth, primarily certain organs, etc.), it can inherently limit the amount and extent of X-rays pass. 
     For example, certain regions or locations of particular individuals (e.g., the embryo in pregnant women, certain organs, certain tissue, radiation-weakened individuals, elderly or informed, certain animals or organisms, etc.) might be particularly susceptible to the application of X-ray electromagnetic radiation, and as such are especially critical to shield from the application of X-rays. As such, it might be particularly desirable to configure at least certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to allow control of the particular range of depth to the prescribed depth of the applied X-rays  120  (as well as their released amount) within the at least the portion of the individual. By limiting the amount and energy level of the X-ray photons of the applied X-rays being applied to the at least some matter of the at least the portion of the individual by such techniques as bandwidth limiting, X-ray energy reduction, filtering, shielding, etc., the application of the X-ray to the user and/or individual can be limited. 
     Allowing relatively precise directional control of applied X-rays  120  using correlators, lenses, etc. such as emitted by the at least one emitter portion  150 , as compared with certain conventional X-ray imagers (conventional transmissive or fluorescent X-rays) can considerably reduce the X-ray dosage to the at least the portion of the individual. Also, X-ray dosages to nearby users can be limited. Such use of relatively low-energy applied X-rays, precise application of applied X-rays to limited region of the individual, and associated reduced dosage of nearby areas, users, and/or individuals by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could improve the public&#39;s and professional perception and acceptance thereof. 
     With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the user such as a doctor, researcher, veterinarian, surgeon, etc. (each of whom may be involved in examination, surgery, and/or research, etc.) can appropriately subsurface visualize, image, and/or provide information relating to the at least the portion of the individual  82 . Depending on context, certain types of Compton scattered X-ray visualization, imaging, or information providing can be applied from nearby or proximate the surface  168  down to within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can vary from the micron range up to and including substantially through a major portion of the individual  82 . 
     The resolution of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be effective for certain diagnosis, examination, surgical, research, and other purposes; and certain embodiments Compton scattered X-ray visualizer, imager, or information provider could provide desired or appropriate resolutions through the visualized, imaged, or information provided portion of the individual  82 . 
     It may be desired for certain visualization, imaging, or information providing applications to adjust and/or control the visualization, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Within this disclosure, the term “control”, as it relates to Compton scattered X-ray visualization, imaging, or information providing, can mean, but is not limited to, controlling the energy level, frequency, angle, additional matter imaged through, and/or other characteristics of the applied X-ray  120  by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Within this disclosure, the term “adjust” can mean, but is not limited to, depending on context, adjusting the at least one range of visualization, imaging, or information providing depth to the at least one prescribed visualization, imaging, or information providing depth. Such control or adjustment can occur by altering or adjusting certain characteristics of the applied X-rays such as energy level, frequency, depth, angle from perpendicular to the surface  168 , etc. 
     Such control and/or adjustment of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can make the Compton scattered X-ray visualizer, imager, or information provider more applicable to a variety of applications. For example, certain controllable embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information a variety of matter within the at least the portion of the individual at a variety of depths, or range of depths. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can adjust the depth of Compton scattered X-ray visualization, imaging, or information providing and/or their resolution based on controlling the X-ray characteristics of the applied X-ray. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be configured to be adjustably tunable, such that the user can adjust the energy of the X-ray photons. By adjusting the energy of the X-ray photons of the applied X-rays, for example, the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth of Compton scattered X-ray visualization, imaging, or information providing into the matter of the at least the portion of the individual can be adjusted. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize steered, focused, directed, filtered, scanned, and/or processed X-rays. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information along a variety of one, two, or three dimensional patterns, in certain instances such as by scanning to create a two or three dimensional visualize, image, and/or provide information within the at least the portion of the individual  82 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be low or non-contact, as well as low or non-invasive, such as by utilizing an embodiment of the emitter portion  150  having no or limited contact with the surface  168 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider may allow the operation and/or structure of the detector portion and the display portion to be at least partially combined. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow the user, or a controller, to alter the Compton scattered X-ray visualization, imaging, or information providing of subsequent or sequential depth visualizations, images, and/or provided information based at least in part on results from prior captured images. Such sequential Compton scattered X-ray visualization, imaging, or information may allow such exemplary users as doctors, surgeons, veterinarians, researchers, etc. to determine the region within the at least the portion of the individual that is being visualized, imaged, or have information provided. It may be desirable to provide for such changes in visualization, imaging, or information providing using a variety of image processing techniques to effect such changes as magnification; zooming; changing a relative angle, depth, or position of the visualization, image, or provided information, and/or changing a variety of other visualizing, imaging, or information providing parameter such as may be desired or useful by the user or individual. 
     A variety of configurations and/or operational combinations of the at least one emitter portion(s)  150 , the at least one Compton scattered X-ray receiving assembly  151 , the at least one detector portion, and/or the at least one display portion(s)  154  may be associated with the Compton scattered X-ray visualizer, imager, or information provider  100 . As described in this disclosure, certain embodiments of the at least one emitter portion  150  can be directed such as to apply X-ray based electromagnetic radiation at a precisely controllable region of the at least the portion of the individual  82 ; such as may thereupon be detected by certain embodiments of the at least one detector portion  152 . Such application and/or detection of the electromagnetic radiation can be done once, multiple continuous times without feedback by a user and/or controller, multiple sequential times with feedback by a user and/or controller, or other ways or combinations thereof. The application or detection of X-rays may rely on transmission of a variety of beams such as pulse, continuous, pencil beam, fan, flooding, or other types of the applied X-rays. 
     Certain embodiment(s) component(s), and/or portion(s) of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as an at least partially external device, such as to depth-examine the at least some matter of the at least the portion of the individual either directly through the matter itself, or alternately below an either external or internal surface  168  of the at least the portion of the individual. For certain external embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the “subsurface” Compton scattered X-ray visualization, imaging, or information providing can, depending upon context, relate to Compton scattered X-ray visualization, imaging, or information providing beneath the skin or other external surface. Certain embodiment(s) component(s), and/or portion(s) of the Compton scattered X-ray visualizer, imager, or information provider can be configured as an at least partially internal device, such as to examine an internal portion of the individual  82  through an incision, or alternately through a normally open opening in the at least the portion of the individual. 
     For certain internal embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , a “subsurface” undergoing visualization, imaging, or information providing can, depending upon context, relate to being applied through a normally open portions of the individual, such as beneath the surface  168 , within a region at least partially forming the lumen, within a cavity, or within another body opening. For internal embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be applied through normally closed portions of the individual (e.g., an incision, a wound, etc.), the term “subsurface” can, depending upon context, including the Compton scattered X-ray visualizer, imager, or information provider  100  being applied through the normally-closed opening, incision, etc. Various embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, or provide information through a variety of such matter as tissue, bone portions, fluid, blood, etc. through the range of depths to the prescribed penetration depth  170 , as described with respect to  FIG. 18 . 
       FIG. 19  shows one embodiment of a flowchart of a Compton scattered X-ray visualization, imaging, or information providing technique  300  that can be performed by the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure of the Compton scattered X-ray receiving assembly  151 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  can include operationally distinct ones of the at least one detector portion  152  from the at least one display portion  154 . Certain embodiments of the subsurface Compton scattered X-ray visualization, imaging, or information providing technique  300  can include one or more operations  302 ,  304 ,  306 , and/or  308  to be applied within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth into the at least some matter. 
     Certain embodiments of operation  302  can include, but is not limited to, applying at least one applied X-ray from an at least one emitter portion  150  towards an at least some matter of an at least a portion of an individual. For example, certain embodiments of the at least one emitter portion(s)  150  can apply X-rays toward the desired matter (e.g., tissue, fluid, bone, teeth, joint, fat, muscle, etc.) of the at least the portion of the individual in a manner that the X-rays can be Compton scattered within the at least some matter. Such application of applied X-rays can thereupon be used by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to allow depth visualizing, imaging, or information providing. A considerable percentage of the applied X-rays that are scattered and returned to be detected by the Compton scattered X-ray receiving assembly  151  could be scattered between within the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth. The value of the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth can be based at least partially on the energy level of the X-ray photons of the applied X-ray  120 . The energy level of the X-ray photons of the applied X-ray  120  is considered to be directly related to frequency. 
     Certain embodiments of the operation  304  can include, but is not limited to, obtaining at least one (e.g., Compton) scattered X-ray that scattered from the at least one applied X-ray at the at least one detector portion  152 . In effect, certain of the Compton scattered X-rays  122  can be received at the detector portion  152 , at least partially based on the scattering of the applied X-rays  120  at the scattering event (e.g., within the at least some matter of the at least the portion of the individual). Certain of the applied X-rays can be applied by the at least one emitter portion  150  during operation  302 . 
     Certain embodiments of the operation  306  (which is optional) can include, but is not limited to, processing the at least one Compton scattered X-ray received during operation  304 , to visualize, image, and/or provide information about the at least the portion of the individual. For example, certain embodiments of the visualization, imaging, or information providing controller  97  can derive visualizations, images, and/or provide information such as can be displayed. 
     Certain embodiments of the operation  308  can include, but is not limited to, deriving the at least one visualization, image, and/or provided information as can be at least partially processed and/or captured during operation  306 . For example, certain embodiments of the display portion  154  and/or the Compton scattered X-ray receiving assembly  151  (which may be a scintillator and/or fluoroscope embodiment) can display a visualization, image, and/or provide information of at least a portion of the matter of the at least the portion of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider may be configured to, at least partially, convert scattered X-rays directly into viewable or visible light, without the processing the scattered X-ray such as may be provided with certain scintillator embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 .  FIG. 21  shows one embodiment of a flowchart of a Compton scattered X-ray visualization, imaging, or information providing technique  400  that can be performed by the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  without processing. Certain embodiments of the subsurface Compton scattered X-ray visualization, imaging, or information providing technique  400  can include one or more of operations  402 ,  404 , and/or  406  as described in this disclosure to visualize, image, and/or provide information using a scintillator (and/or fluoroscope) embodiment of the Compton scattered X-ray receiving assembly  151 . Certain scintillator (and/or fluoroscope) embodiments of the Compton scattered X-ray receiving assembly  151  can visualize, image, or provide information within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth into the matter of the at least the portion of the individual. 
     Certain embodiments of the operation  402  can include, but is not limited to, applying at least one applied X-ray from the at least one emitter portion towards the at least some matter of the at least the portion of the individual. For example, certain embodiments of the at least one emitter portion(s)  150  can apply X-rays toward the desired matter (e.g., tissue, fluid, bone, teeth, joint, fat, muscle, etc.) of the at least the portion of the individual in a manner that the X-rays can be Compton scattered within the matter. 
     Certain embodiments of the operation  404  can include, but is not limited to, receiving at least some (e.g., Compton) X-ray at the at least one Compton scattered X-ray receiving assembly  151  as described in this disclosure, in response to the applied X-rays  120  applied by the at least one emitter portion  150 . A considerable percentage of the applied X-rays that are scattered and returned to be detected by the Compton scattered X-ray receiving assembly  151  will be scattered through the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth. Such scattering can be based at least partially on the energy level (or frequency, which is related thereto) of the X-ray photons of the applied X-ray  120 , as described in this disclosure. 
     Certain embodiments of the operation  406  can include, but is not limited to, deriving at least one visualization, image, or provided information at least partially in response to the receiving the at least one scattered X-ray at the at least one Compton scattered X-ray receiving assembly  151 . For example, certain scintillator (and/or fluoroscope) embodiments of the display portion  154  and/or the Compton scattered X-ray receiving assembly  151  can display a depth visualization or image of at least a portion of the matter of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  thereby can provide a mechanism to visualize, image, and/or provide information down to, or at, one or more depths (in many instances controllably) into at least partially X-ray matter such as to capture depth visualizations, images, and/or provided information. Within this disclosure, much of the matter being depth-imaged by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be expected to be interspersed, mixed, compounded, or at least partially combined with other matter such as bones, metal, etc. within the individual such as typically exists in at least certain portions of the individual  82 . Certain embodiments of the X-ray Compton scattered X-ray, such as can be performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , can thereby be used to visualize, image, and/or provide information matter that can be at least partially combined with relatively electromagnetic radiation-Compton scattered X-ray matter. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be used to visualize, image, and/or provide information at least portions of certain matter that is relatively “hard”, considering the applied X-rays  120 , such as bones, bone fragments or portions, spinal portions, cranial portions, metal, implants, etc. Such re-configurations as altering the frequencies of the applied X-rays  120  may be used to configure the Compton scattered X-ray visualizer, imager, or information provider  100  to visualize, image, and/or provide information matter(s) having varied characteristics. By depth visualizing, imaging, or information providing of hard matter such as bones, spinal portions, certain implants, etc., it can become possible to examine a two-dimensional, or three-dimensional portion of the bone, etc. with considerable resolutional accuracy. Such depth visualizing, imaging, or information providing of hard matter can be controlled and/or adjusted as described in this disclosure. Such Compton scattered X-ray visualization, imaging, or information providing of hard matter can be performed prior to surgery or examination, during surgery or examination, following surgery or examination. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information hard matter in combination with other matter. For example, a bone can be imaged in combination with associated joints, muscles, tendons, surgical pins, plates, etc. Additionally, a brain portion can be visualized, imaged, or have information provided relative to associated cranial portions (e.g., skull), etc. Providing such adjustability or control of Compton scattered X-ray visualization, imaging, or information providing can allow doctors, surgeons, dentists, etc. to obtain accuracy of Compton scattered X-ray visualization, imaging, or information providing of a variety of matter within the at least the portion of the individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, or provide information relating to a combination of at least some soft matter such as tissue, blood cells, bodily fluids, etc. as combined with certain embodiments of the at least some hard matter such as bones, teeth, etc. Such visualization, imaging, or providing information of a combination of at least some hard matter with at least some soft matter may be particularly useful when considering junction matter regions, such as the intersection of gums with teeth; the intersection of bones with tendons, ligaments, muscles, tissue, etc. 
     A variety of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to image edges, sides, inconsistencies, or non-uniformities of matter, tissue, organs, etc. It may therefore be possible to locate particular organs, matter, tissue, etc. based on such inconsistencies, or non-uniformities of the organs, matter, tissue, etc. For example, as applied X-rays  120  are applied to visualize, image, and/or provide information a region of the at least the portion of the individual where an organ is situated, the edge portion of the organ may scatter the applied X-rays in a direction that differs from the remainder of the organ. Such Compton scattered X-ray along the edge may lead into a detectable difference of the depth Compton scattered X-ray image at the edge of the X-ray Compton scattered X-ray organ. Such differences of characteristics of Compton scattered X-ray based at least in part on angle, position, or other aspect of the matter can be used by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure. 
       FIG. 8  shows one embodiment of the emitter portion  150  that can be included in certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, while  FIG. 9  shows another embodiment. Certain embodiments of the at least one emitter portion  150  can emit the applied X-rays toward the at least the portion of the individual  82  over an angle such as with a pencil beam, fan beam, area beam, or other beam; while other embodiments can emit the applied X-rays in a narrow beam such as a pencil beam. Certain embodiments of the emitter portion  150  can emit collimated X-rays, while others can emit incoherent X-rays. Certain embodiments of the at least one emitter portion  150  can include such adjustable optical elements as Bragg optics elements to adjust the pattern/direction of the applied X-ray emission, while others may not be adjustable or controllable. The configuration, design, and usage of certain embodiments of the emitter portion  150  can depend, at least in part, on the particular characteristics of the Compton scattered X-ray visualization, imaging, or information providing (as well as the characteristics of the at least the portion of the individual being visualized, imaged, or have information provided). 
     In general, certain embodiments of the emitter portion  150  are therefore configured to direct at least one X-ray towards the at least the portion of the individual. Certain embodiments of the at least one emitter portion  150 , can include, but are not limited to, a power source  836 , a cathode  832 , a field emission tip  850 , and/or an anode  834 . Other illustrative potential structures of the at least one emitter portion  150  are described in this disclosure, while still others are generally understood by those skilled with X-ray tubes and generating devices. Certain embodiments of the power source  836  and the cathode  832  can be arranged in an electron circuit such as to provide an electric (e.g., electron) flow from the cathode  832 , such as can be at least partially discharged via the electron emitter tip  850  and the anode  834 . Certain embodiments of the electron emitter tip  850  can be in electrical communication with the cathode, such as to be configured as to be capable of discharging the electron flow that can be at least partially directed at the anode  834 . 
     Certain embodiments of the electron emitter tip  850  may be configured as an electron discharge region that can generate and/or direct the electron flow in a pattern, frequency, energy level, configuration, or other parameter as described with respect to  FIG. 8 . Certain embodiments of the electron emitter tip  850  are configured to establish the electron flow, and as such may include such elements as a triode, antenna, nanostructure, or other such component. Certain embodiments of the electron emitter tip  850  can also be configured to include one or more (carbon) nanotubes, which may be effectively configured as electromagnetic radiation antennas. Certain embodiments of the electron emitter tip  850  can thereby utilize one or more discrete elements, while other embodiments can utilize a number or array of carbon nanotubes, etc. 
     Certain embodiments of the electron emitter tip  850  can be fixed, while other embodiments can be adjusted or displaced such as to change such as to alter the pattern of electron emission, such as by moving the electron source. One example of a movable or adjustable electron emitter tip  850  can include, for example, utilizing adjustment or displacement of a flexible carbon nanotube electrically coupled to the cathode. 
     Certain embodiments of the anode  834  can be configured and/or biased during operation as to attract electrons from the combination of the cathode  832  and/or the electron emitter tip  850 . Upon contact of the electron flow into certain embodiments of the anode  834 , certain embodiments of the anode can thereupon generate X-ray photons of the desired frequency and/or energy level. In certain embodiments of the emitter portion  150 , the electron flow emanating from the electron emitter tip  850  can remain substantially static, and as such may not be directable or scannable. With other embodiments of the emitter portion  150 , the electron emitter tip  850  of the cathode  832  can steer, scan, or otherwise displace the electron flow to the desired location relative to the anode  834 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to include a stepper motor, or other motor or displacement mechanism (not shown) to control or adjust the positions of the emitter portion  150  and/or the detector portion  152 . The respective emitter portion  150  and/or detector portion  152  may be configured to operationally pan and tilt during operation such as to provide a desired degree of adjustability. Certain embodiments of the electron emitter tip  850  can be configured as an X-ray source (e.g., in certain instances the size may be in the small mm range such that it may, in certain instances, fit within certain blood vessels or lumens such as to allow depth visualizing, imaging, or information providing from these locations). In other embodiments, the size of the electron emitter tip  850  may be considerably larger such as to interface with an external or larger portion of the individual  82 . 
     Certain embodiments of the electron emitter tip  850  beam can be configured to be displaceable or moveable such as to allow control and/or adjustment of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as by scanning, shifting, axially moving, beam focusing control, rotating, panning, or otherwise moving to alter the path of the electron flow. For example: one or more Micro Electro-Mechanical System (MEMS) devices, a rotating crystal, an electromechanical or X-ray scanning mechanism, or other suitable means may be included in the certain embodiments of the electron emitter tip  850  such as to provide control and/or adjustment of the electron emitter tip. Certain embodiments of the emitter portion  150  can be configured to produce X-rays that are at least partially incident on a lens (not shown, but which may include a crystal which is configured as a lens) that can be displaceable to move and/or scan the X-ray beam. Alternately, certain embodiments of the emitter portion  150  can be configured as an array type device, with different ones are different groups of the elements being a controlled either manually or at least partially by the depth visualization, imaging, or information providing controller  97 . Such scanning of the X-ray beam can follow a raster-type scan, use a fan type beam, pencil type beam, or other scan, perhaps similar to those utilize to in certain other conventional tomography scanners, or may follow some other pattern. In certain instances, the scanning of the at least one emitter portion  150  may be coordinated with the scanning of the at least one detector portion  152 , or alternately a scanning detector portion may be associated with an emitter portion that generates X-rays which effectively “flood” the at least the portion of the individual  82  being visualized, imaged, or have information provided. The selection of the particular scanning or flooding configuration may affect X-ray dosage of the user and/or nearby individuals, as described in this disclosure. 
     Various embodiments of the power source  836 , as described with respect to  FIG. 8 , may be configured as desired, as long as it provides adequate power to the cathode to establish the electron flow from the particular embodiment of the electron emitter tip  850 , depending on the configuration of electron emitter tip as well as the anode. Certain embodiments of the emitter portion  150  can thereby be configured to direct electrons, as provided by the power source  836 , the cathode  832 , and/or the electron emitter tip  858 . The electrons may therefore be directed from the electron emitter tip  850  to the anode  834  as described with respect to  FIG. 8 . Altering or controlling the electron flow may have a corresponding effect on the generation of photons by the anode  834 . Certain embodiments of the emitter portion  150  may alternately be powered optically, such as to include the photon generator  880  as applied to the power source  836 , as described with respect to  FIG. 9 . 
     Certain embodiments of the photon generator  880  can alternately utilize, for example, an optically fed photoelectric stack, an optical fed battery, a solar panel, or a variety of other device that can generate X-ray photons. Certain embodiments of the at least one emitter portion  150  utilizing the photon generator  880  as described with respect to  FIG. 9 , can be adjustable, controlled, fixed, dispersed, and/or focused, etc. as to control and/or adjust generation of X-ray photons as described with respect to the  FIG. 8  embodiment of the emitter portion. 
     With certain embodiments of the emitter portion  150 , as described with respect to  FIG. 8 , an electron grid (not shown) may be positioned, adjusted, and/or controlled from a location such as operationally proximate to the electron flow. For example, the electron grid may be situated adjacent a path at least partially situated between the electron emitter tip  850  and the anode  834 . Certain embodiments of the electron grid may be configured, upon activation, to steer, scan, or otherwise control the flow or velocity of electrons passing from the electron emitter tip  850  to the anode  834 . Such steering, scanning, accelerating, decelerating, or otherwise controlling the flow or velocity of electrons can in addition control or alter the characteristics or position(s) at which the photons generated contact the particular anode  834 . 
     Certain basic embodiments of the anode  834  can be configured in a variety of forms. For example, the anode can include a thin metal foil, or other configuration, that can be positioned in suitable proximity to the electron emitter tip  850 . Certain embodiments of the anode  834  can be provided to be controllable and/or adjustable such as to include at least one anode wheel, cassette, cartridge, etc. (not shown) that can emit X-ray photons whose characteristics can be adjusted and/or controlled, such as by displacement, rotation, etc., such as to provide varied anode metals or other materials anodes (or having different shapes, dimensions, or other configurations) in communication with the electron flow. 
     By using an anode wheel, cartridge, canister, or other such mechanism that can alter the material and/or configuration of the anode, the characteristics of the X-ray photons (such as energy level and/or frequency) being generated by the at least one emitter portion can be controlled or altered. Such controlling and/or altering of the X-rays being emitted can control and/or alter the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth, and thereby the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth, being performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure. Certain other uses of anode wheels is known in certain conventional X-ray tubes, which can function largely to maintain all portions of the anode within acceptable temperature ranges by altering the portion of the anode wheel which the electron flow contacts, and is therefore being instantaneously heated by the electron flow. The anode wheels could also include a motive mechanism (not shown) to allow suitable rotation and/or displacement of the anode wheel (either rotationally and/or axially) such as may utilize a stepper motor, a pneumatic drive, an electric motor, etc. Certain embodiments of the anode wheel could also include a variety of control mechanisms (not shown) to control such rotation and/or displacement. A variety of such control, rotation, and/or displacement mechanisms are generally understood by those skilled in the anode wheel art. 
     Certain embodiments of the anode  834  can thereby be configured to generate the X-ray photons at controllable and/or adjustable energy levels, frequencies, or other characteristic based at least in part on the characteristic of the electron flow being applied to the anode  834 , and additionally on the material of the anode  834 . As such, it may be possible to generate X-rays having particular characteristics by selecting particular materials (e.g., different metals) or configurations of the anode that can be either shifted in position relative to (e.g., in front of) the electron flow. Additionally, moving or angling the anode relative to the electrons (or vice versa) may result in different characteristics of the applied X-ray. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be adjusted or controlled by shifting or steering the electron flow relative to the anode  834  such that the portion of the anode which the electron flow contacts may be made of multiple varied materials and/or configurations. Certain embodiments of the anode  834  can be configured in the shape of a wheel (e.g., to form an anode wheel) that when rotated can result in positioning of the desired metal in contact with the electron flow such as to provide control and/or adjustment of the applied X-rays. 
     There can be a variety of additional components that can be applied to certain embodiments of the emitter portion  150  within certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIGS. 8  and/or  9 . Certain embodiments of the at least one emitter portion  150  can further include a collimator or X-ray lens  842  that can focus, angle, or direct the photons emitted from the emitter portion as desired. Certain embodiments of the X-ray lens or collimator  842  can be controllable such as to provide control of such Compton scattered X-ray visualization, imaging, or information providing processes as emitter portion directability, signal or image filtering, image zooming, starting, stopping, or pausing Compton scattered X-ray visualization, imaging, or information providing, signal or image processing, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize an optional vacuum (at least partially evacuated) portion  854 , as described with respect to  FIGS. 8  and/or  9 , which can be utilized to limit contact of the electrons of the electron flow traveling from the cathode  832  to the anode  834  with extraneous gas, air, suspended solids, liquid, and/or other minute particles suspended in the air. As such, certain embodiments of the optional vacuum (at least partially evacuated) portion  854  can limit interaction of the photons with additional particles. Additionally, certain embodiments of the vacuum portion  854  may thereby be configured to at least partially limit combustion of certain of the electronic components contained therein as a result of the heat being generated upon the exposure to air. Certain embodiments of the vacuum (at least partially evacuated) portion  854  can thereby be configured as a vacuum tube, such as may be configured as an interlumenal X-ray source and is generally understood by those skilled in the X-ray tube technologies. 
     Certain embodiments of a capacitor  830  can optionally be arranged in an electronic circuit including the power source  836  and the cathode  832  as described with respect to  FIG. 8 . Certain embodiments of the cathode  832  can be configured with the capacitor  830  to store particular levels of electric voltage such as can be applied to the cathode  832 , and subsequently released as desired as the electron flow via the electron emitter tip  850 . 
     While this disclosure describes certain embodiments of the at least one emitter portion  150 , it is to be understood that any mechanism that can transmit X-rays whose frequency, energy level, or other characteristic can be controlled or adjusted may be used in certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . The embodiments of the at least one emitter portion  150  as described in this disclosure with respect to  FIGS. 1 ,  8 ,  9 , as well as other locations in this disclosure, is intended to be illustrative in nature, but not limiting in scope. As mentioned in this disclosure, for example, certain embodiments of the emitter portion  150  could be at least partially replaced by an optical-generating portion as described with respect to  FIG. 9 . It is envisioned that the at least one emitter portion  150  can thereby be configured slightly differently in operation and/or configurations, such as to generate photons in a different manner, but are still intended to be within the scope of the present disclosure as being within the claimed limitations. For example, the vacuum (evacuated) portion  854 , such as a vacuum tube, may include one or more discrete emitter tip elements or one or more (carbon) nanotubes be configured as the electron emitter tip  850  as described with respect to  FIG. 9 . 
     Certain embodiments of the emitter portion  150  of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIGS. 8 and 9 , may therefore be adjustable and/or controllable such as by being configured for repositioning, angling, filtering, or some other suitable technique. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include a stepper motor such as may be configured such that it can pan and tilt, thereby providing some control and/or adjustment to emitted photons that can be emitted by the at least one emitter portion  150 . Such stepper motors may thereupon be considered to represent one illustrative embodiment of an adjustment or control portion that can also be accomplished by use of a photon lens or collimator  842 . 
     Certain embodiments or configurations of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1 , can visualize, image, and/or provide information teeth, dental plates or surfaces  168 , etc. such as may be used by dentists, oral hygienists, etc. as described with respect to  FIG. 22 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow Compton scattered X-ray visualization, imaging, or information providing of at least one tooth at one or more angles, positions, magnifications, etc. as desired. The particular display portion  151  that may be selected may be based upon user preference, ease of use, design choice, etc. The embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , as illustrated in  FIG. 22 , could be attached to a probe, for example. Similar user configurations of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to tools being used by doctors, surgeons, veterinarians, as well as other users as described in this disclosure. As the visualization, imaging, or information providing can be performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  from a number of different angles, positions, etc., it may be desired to display at least the display portion reflect the change in angle, position, etc. 
     As the user/dentist, as illustrated in  FIG. 22 , moves or repositions the probe, it might be preferred to have the Compton scattered X-ray visualizer, imager, or information provider  100  to adequately reflect the angle or position of the visualization, imaging, or information providing. With sufficient changes of the angle, material of the anode, and/or position of the visualization, imaging, or information providing, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can derive and/or display a three-dimensional model of the one or more teeth. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore provide information or images such as to determine where and/or how to treat the at least the portion of the individual (patient). Certain dental embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to a dental drill, and thereupon be displayed at a location and magnification such as can be made viewable and/or visible to the user. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are operatively associated with certain tools, tactile providers, etc. need not be directly connected (or may be removably connected, to the tool, tactile provider, etc. 
     Certain of the images can also be provided to the patient as well using the same or other Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , when attached to a tool performing a desired operation, can act as a double check to ensure the tooth being imaged by the user is indeed the one that should be dealt with. For example, a dentist can check that the correct tooth is being drilled. A doctor can ensure the correct arm, leg, or other body part is being treated, etc. There can be a large variety of tools that may be used by such users as surgeons, assistants, veterinarians, dentists, etc. as generally understood to be used in each particular area. It is envisioned that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be applied to a variety of tools and/or tactile feedback devices that could benefit by use with visualization, imaging, or information providing, as described in this disclosure. 
     The location of the drill or other tool including certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as taken relative to the decayed or damaged portions of the teeth can be detected on a substantially real-time, intermittent, or as desired basis. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to provide tactile feedback, which in the case of a dentists are dental assistant would be useful in determining the security of a tooth, the degree of tooth decay within a particular tooth, the security of braces, caps, filling, dental plates, or other device within the individual. By using certain dental depth visualizing, imaging, or information providing embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , it may not be necessary for dental patients to use conventional X-ray plates (positioned between the teeth of the person that has to be bitten down by the person) during dental X-rays thereby making dental visits more pleasant. 
     Such dental depth visualizing, imaging, or information providing can be performed substantially parallel to the drilling or other. As such, the user such as the dentist or dental hygienist can be provided an improved indication of where they are drilling or treating relative to damaged or decayed teeth. Certain embodiments the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as clinic, emergency, or home-test kits, by which people could check the state of certain illness shows, sicknesses, injuries, painful or uncertain orthodontia, gum, dental, skin, or other conditions, etc. The user can thereby be provided with considerable detail as to the condition of, or decay within the teeth from particularly desired angles. 
     Additionally, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow depth visualizing, imaging, or information providing of the gums, portion of teeth hidden by the gum, and other matter and portions within or close to the mouth that may be useful for dental use. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information the relating to teeth, gums, tongue, blood vessels or pools, or other general aspects, etc. Certain dental embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can operate through the cheeks, and as such the Compton scattered X-ray visualizer, imager, or information provider  100  can be situated either at partially external to, or at least partially internal of the at least the portion of the individuals mouth. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide “freezing” the state of certain depth visualizations, images, and/or provided information as desired by the user or operator, or alternately as controlled by the Compton visualization, imaging, and/or information providing controller. Such freezing of the depth visualizations, images, and/or provided information can include maintaining an image of the at least the portion of the individual displayed on the display portion  154  and/or the Compton scattered X-ray receiving assembly  151 . Since generating new images may require an application of applied X-rays  120  to the at least the portion of the individual, it may be desired to limit such application of the applied X-rays. As such, certain users can judiciously control the application of X-rays to the at least the portion of the individual, the user, and/or others in the vicinity during the Compton scattered X-ray visualization, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider. 
     Certain dental or orthodontia embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  of  FIG. 22  can also be used to visualize, image, or provide information relating to teeth of human individuals wearing braces. It is presently difficult, if not impossible, to accurately X-ray image teeth covered by brace bands, wires, etc. due to the distortions caused by the wires, bands, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide such accuracy and limited spatial scope of visualization, imaging, or information providing, as to allow Compton scattered X-ray visualization, imaging, or information providing from a single uncovered face of a tooth (e.g., biting surface). As such, certain teeth covered by braces, bands, etc can be visualized, imaged, or have information provided thereto, potentially from a variety of controllable and/or adjustable angles, positions, etc., during orthodontia treatment. Teeth, dental surfaces, fillings, etc. can be visualized, imaged, or have information provided from a variety of angles, positions, etc. such as to provide an improved indication of their configuration, solidity, health, etc. The amount of, and reliability of, dental treatment that can be performed based at least in part on X-rays can thereby be increased during orthodontia treatment. 
     While this disclosure have described certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as being substantially externally-applied devices, it should also be understood that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be an at least partially internal device. Such at least partially internal devices can be applied to within the at least the portion of the individual using a scope, a needle, through an incision, via a normally open opening, and/or via a normally closed opening.

The illumination portion  134  could be used to provide the applied X-rays as described elsewhere to the individual, which thereupon can be scattered. Certain endoscope embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereupon be configured to receive the scattered X-rays, viewable and/or visible light, visualization, image, or provided information from the individual. 
     The scope embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include a variety of the Compton scattered X-ray receiving assembly  151 . Certain embodiments of the Compton scattered X-ray receiving assembly  151  can include a scintillator (and/or fluoroscope), perhaps with a photomultiplier as described in this disclosure to amplify a relatively weak viewable and/or visible-light output. Certain embodiments of the Compton scattered X-ray receiving assembly  151  can include a fluoroscope as generally known in the art which may operate in certain ways similar to the scintillator (and/or fluoroscope). Certain embodiments of the Compton scattered X-ray receiving assembly  151  can include a detector portion in combination with a display portion as described with respect to  FIG. 1  in this disclosure. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be at least partially adapted with, or at least partially configured to act as, a variety of tools. Such tools can include, but are not limited to: a Bovie electrocautery device as generally understood in the art, an ablator, a cutter, a gamma knife, a scalpel, a saw, a tactile feedback provider, a contact-type probe, a dental drill, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured as being attached a scope, tube, catheter, or other instrument or tool that can be configured to be inserted into the at least the portion of the individual. For example, certain endoscope embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be configured as described with respect to  FIG. 23 . Certain configurations of the Compton scattered X-ray visualizer, imager, or information provider  100  may be provided with the emitter portion being situated relative to an endoscope via a surgical implant, and thereby may be similar to other embodiments of the Compton scattered X-ray visualizer, imager, or information provider in certain ways, but with the emitter portion placed inside the individual. 
     Certain scope-based embodiments of the emitter portion  150 , as described with respect to  FIG. 23 , may be largely applied to an internal portion of the individual such as to include an interluminal X-ray source; while other embodiments of the emitter portion may be applied to an external portion of the individual. Certain embodiments of the emitter portion  150  may be powered by a variety of power sources (traditional or non-conventional) including, but not limited to, solar cells that may include traditional or untraditional power sources.

Certain optically fed embodiments of the emitter portion  150  may also include automated shutdown or other safety aspects relating to emission of X-ray based electromagnetic radiation. Certain embodiments of the emitter portion  150  may be implanted within the at least the portion of the individual such as to allow visualization, imaging, or information providing (using certain embodiments of the Compton scattered X-ray receiving assembly  151 ) on a more continuous basis. Such implants of at least portions of the Compton scattered X-ray visualizer, imager, or information provider  100  can be particularly useful for difficult to access portions of the body, such as the heart, brain, or certain other organs or regions of the body, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to control X-ray generation and/or direction at least partially by accelerating or directing electrons for X-ray production. Such accelerating or directing the electrons can effectively reduce X-ray path length, and hence limit multiple Compton scattered X-ray events. Certain embodiments of the at least one emitter portion  150 , and/or at least one detector portion  152  can be configured such as by being placed by a scope or other such device in a normally open opening, normally closed opening, or other lumen, such as colon, esophagus, mouth, throat, stomach, blood vessels, lungs, gut, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can also be applied to cranial, brain, or spinal depth visualizing, imaging, or information providing. It may be difficult to visualize, image, and/or provide information within the skull using certain conventional imaging modalities, as a result of deflections of certain electromagnetic radiation within the interior (e.g., substantially concave) surface  168  of the skull and the associated distortions. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to access the brain via such openings in the skull as the ear sockets, mouth opening, and/or sinuses. Such Compton scattered X-ray visualization, imaging, or information providing of the brain through such key-hole opening should experience relatively limited visualization, imaging, or information providing distortion, as compared with Compton scattered X-ray visualization, imaging, or information providing at least partially through the skull, boney matter, or other such X-ray distorting or shielding regions. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be applied to relatively small regions of the body, and thereby apply relatively small overall dosages of X-rays. Certain embodiments of the Compton scattered X-ray visualization, imaging, or information providing can be controllably or adjustably applied in small regions, from different angles, etc., than certain conventional full-scale X-ray or certain conventional tomography imagers. 
     For instance, certain X-ray tomography-type Compton scattered X-ray visualization, imaging, or information providing imagers can capture a visualization, image, or provide information by scanning a series of scans relatively shallow into the at least some matter of the at least one portion of the individual from a variety of angles and/or positions. Such scanning can be performed using a variety of respective applied X-rays and/or scattered X-rays that can be respectively applied/received using respective arrays of emitter portion(s)  150  or Compton scattere X-ray receiving assemblies  151 ; or alternately one or more of the respective emitter portions and/or the Compton scattered X-ray receiving assemblies  151  that can be moved, scanned, angled, or otherwise repositioned. For instance, the certain array embodiments of the emitter portion  150  or Compton scattere X-ray receiving assemblies  151  can be configured to roughly conform to the general shape of the portion of the individual being imaged, or alternately in some other configuration. As the distinct emitter portion element(s)  150  are actuated to provide the applied X-rays  120 , then the corresponding embodiment of the Compton scattered X-ray receiving assembly  151  can collect the data corresponding to the visualization, image, or provided information for each emitter portion element(s) including some unknowns relating to particular visualization, imaging, or information providing limitations. As a number of the distinct emitter portion element(s)  150  that direct the applied X-rays  120  under different directions, positions, energy levels, or other conditions decreases, the number of unknowns relating to particular visualization, imaging, or information providing limitations for at least some matter of the at least the portion of the individual correspondingly decreases, and a more complete and accurate visualization, image, or provided information can be obtained using tomographic techniques. 
     A similar tomographic technique or embodiment of the of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to directing one or more emitter portion(s)  150  or Compton scattere X-ray receiving assemblies  151  at different positions, angles, energy levels, etc. Such techniques can involve physically repositioning and/or angling of the emitter portion  150  and/or the Compton scattered X-ray receiving assembly  151  itself/themselves such as to follow a scan, circular motion around the at least the portion of the individual, or other type of translation, angling, repositioning, changing of energy levels, etc. Alternately, a redirecting device of the applied X-ray or Compton scattered X-ray can be used, such as a filter, lens, modulator, shield, collimator, endoscope or other bendable, movable, or twistable scope or other emitter portion could be used in different embodiments, as described in this disclosure. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can, by using low energy applied X-rays  120 , provide a relatively low-power version of the applied X-ray beam  120  which can be highly suited for intracranial visualization, imaging, or information providing and examination. The power of the applied X-ray beam may generally be configured or set at a level to be insufficient to penetrate, in large numbers, to another region that may not be depth visualized, imaged, or information provided. Such would be the case of brain depth visualizing, imaging, or information providing to limit transmission of excessive doses of X-rays to the cranium, brain, brainstem, embryo, or other such the region, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be configured to visualize, image, and/or provide information in the brain, or other intracranial tissue. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could operate with relatively high resolution, or alternately with lower resolution as desired or designed compared to other imaging modalities, and may thereby be similar in certain aspects to that of conventional MRI. Certain embodiments of the at least one emitter portion  150  can thereby be configured to use mono-energetic, collimated, or other sources. When using at least partially internal (e.g., in-body) embodiments of the at least one emitter portion  150 , it may be possible to increase X-ray capture fraction by having multiple in-body detector portions  152 , not just a single detector portion associated with the emitter portion. With the different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , it is likely to be desired to limit dosages of X-rays as applied to the at least the portion of the individual  82  and/or the user (e.g., physician, dentist, veterinarian, assistant, researcher, etc.). 
     A variety of embodiments of the at least one detector portion  152  can be associated with the Compton scattered X-ray visualizer, imager, or information provider  100  as described at various locations in this disclosure. Certain embodiments of the at least one detector portion  152  may be considered as functionally associated with the at least one display portion  154 , since the at least one display portion may be configured to display a version (which may be resized, filtered, scanned, computed, and/or otherwise modified) of what was detected by the at least one detector portion. 
     Certain embodiments of the at least one detector portion  152  and/or the Compton scattered X-ray receiving assembly  151 , as included in certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , can be configured of various sizes, shapes, configurations, and may include a single detector portion or an array of detector portion elements. For example, those embodiments of the Compton scattered X-ray receiving assembly  151  utilizing a distinct detector portion  152  and  154  as described with respect to  FIG. 18  differ from those scintillator (and/or fluoroscope) embodiments of the Compton scattered X-ray receiving assembly utilizing a combined detector and display portion as described with respect to  FIG. 20 . The dimensions of each detector portion element and/or the Compton scattered X-ray receiving assembly  151  can be selected based on such criteria as the desired application, usage, and/or the desired or designed Compton scattered X-ray visualization, imaging, or information providing resolution. 
     A variety of depth visualizations, images, and/or provided information including, but not limited to, tomography depth visualizations, images, and/or provided information can be constructed by scanning the X-ray beam received at the at least one detector portion  152  over a volume of interest of the at least the portion of the individual  82 . As such, the at least one detector portion  152  may be considered as detecting the Compton scattered rays, with time-of-flight, spectral, and/or spatial resolution of the Compton scattered X-rays or other electromagnetic radiation. Specific X-ray energies can be used by the at least one detector portion to detect spectral features (e.g. absorption edges or fluorescence spectra) of specific X-rays received (e.g., Compton scattered) from particular ones of the at least the portion of the individual  82 . The targeted portion of the individual can be at least partially endogenous, such as being produced from within the at least the portion of the individual (such as iron in blood, or calcium in tumors). Alternately, the targeted portion can be at least partially exogenous such as being produced outside of the at least the portion of the individual (e.g. high-Z contrast agents that migrate, bind, or are otherwise introduced into regions of interest). The emitted flux, energy level, or frequency of each X-ray photon can be tuned as to detect particular structures, organs, materials, etc. at certain depths and/or regions, as being detected by the at least one detector portion  152 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can thereby capture a series of depth visualizations, images, and/or provided information, in which the at least one emitter portion and/or the at least one detector portion can operate sequentially utilizing feedback by the user and/or visualization, imaging, or information providing controller  97 . Such control and subsequent feedback can be used as to alter and/or control the relative position, angle, magnification, or other aspect of the subsequent depth visualizations, images, and/or provided information. The initial depth visualizations, images, and/or provided information that have been captured can thereupon be displayed to the user at least partially using the at least one display portion  154  and/or the Compton scattered X-ray receiving assembly  151 . The location, magnification, angle, and/or other characteristics of the subsequent depth visualizations, images, and/or provided information can be determined, at least in part, from the results of the prior depth visualizations, images, and/or provided information based at least partially on user input. 
     By allowing capturing of sequentially adjustable depth visualizations, images, and/or provided information, the users and/or individuals can observe the at least the portion of the individual  82  as they may desire. As such, the depth visualizing, imaging, or information providing being performed by the Compton scattered X-ray visualizer, imager, or information provider  100  can be adjusted and/or controlled. Consider that with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , a user such as a physician, dentist, technician, assistant, etc. can obtain some preliminary depth visualizations, images, and/or provided information from certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider to locate a desired examining feature. Thereupon, the depth visualizing, imaging, or information providing can be adjusted in subsequent images such as more closely or more accurately scan or examine at a desired location, angle, etc., such as to scan or examine for a cancerous growth. 
     Alternately, the user can use some embodiments of the Compton scattered X-ray visualizer, imager, or information provider to locate a desired organ or the at least the portion of the individual  82 . Thereupon, the Compton scattered X-ray visualization, imaging, or information providing as performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be modified, altered, repositioned, magnified, etc. such as to more closely or more accurately examine some aspect of the desired examining feature at a variety of angles, positions, magnifications, etc. Each one of the respective at least one emitter portion  150 , at least one detector portion  152 , at least one display portion  154 , and/or the at least one combined detector/display portion  155  (e.g., scintillator and/or fluoroscope), can be respectively fabricated and/or respectively formed. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described at a variety of locations through this disclosure, may alternately be scintillator-based and/or fluoroscope-based. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may allow feedback techniques to allow users and/or visualization, imaging, or information providing controller  97 . Such feedback techniques may alter and/or control Compton scattered X-ray visualization, imaging, or information providing of subsequent depth visualizations, images, and/or provided information based at least in part on results or user input based on prior captured visualization, imaging, or information providing. Certain embodiments of the at least one Compton scattered X-ray receiving assembly  151 , including the at least one display portion  154  as combined with the at least one detector portion  152 , can therefore be configured as a scintillator and/or fluoroscope, as described with respect to  FIG. 20 . With scintillator or fluoroscope embodiments of the Compton scattered X-ray receiving assembly, X-ray photons can be converted to viewable and/or visible photons as described with respect to this disclosure. 
     Certain embodiments of the scintillators or fluoroscopes can be configured including a substance that can absorb such electromagnetic radiation as X-rays, and thereupon can fluoresce, or otherwise provide such as by Compton scattered X-ray or other imaging mechanism, viewable and/or visible light (viewable and/or visible photons) at a characteristic X-ray frequency or energy level depending upon the received X-ray radiation. The fluorescing of the viewable and/or visible light may, as generally understood by those skilled in the art, be viewed as releasing the previously absorbed energy into or from the X-ray photons. 
     Certain embodiments of the at least one Compton scattered X-ray receiving assembly  151  of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be configured to include scintillators and/or fluoroscopes can convert the scattered X-rays directly to viewable and/or visible light, without associated detectors and displays associated with certain embodiments of the Compton scattered X-ray receiving assembly  151 . Certain configurations of conventional scintillators or fluoroscopes can be configured as optical detectors, displays, Compton scattered X-ray visualization, imaging, or information providing, etc. such as described with respect to U.S. Pat. No. 7,057,187 to Yun et al., entitled Scintillator Optical System and Method of Manufacture (incorporated herein by reference in its entirety). Certain embodiments of scintillator can be used for medical depth visualizing, imaging, or information providing as described with respect to U.S. Pat. No. 6,895,077 to Karellas et al., entitled System and Method for X-Ray Fluoroscopic Imaging (incorporated herein by reference in its entirety). Certain conventional CAT scanners utilize scintillator technology. 
     It is likely that the scintillator (and/or fluoroscope) embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be useful in screening the at least the portion of the individual, perhaps at shallow depths and/or for homogeneous matter (using Compton or fluoroscopy techniques), for skin aberrations, such as cancers, tumors, lesions, etc. As such, the user might scan the users for such aberrations that might occur near the surface  168 , and the image processing associated with depth visualizing, imaging, or information providing such aberration with particular concern about processing Compton scattered X-rays Compton scattered X-ray at different depth being limited. 
     Certain scintillator (and/or fluoroscope) embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be characterized in this disclosure by the characteristics of their viewable and/or visible photonic output. The characteristics of their viewable and/or visible photonic output can include, but are not limited to, e.g., strength, energy level, and/or frequency of emitted viewable and/or visible photons as a function of absorbed X-ray electromagnetic radiation, fluorescence decay times, and/or optical transparency at wavelengths of their emitted viewable and/or visible electromagnetic radiation and/or other such factors. Scintillators (and/or fluoroscopes) may thereby be considered as operating by translating X-ray electromagnetic radiation into viewable and/or visible light electromagnetic radiation. As such, at least certain X-rays detected by the at least one detector portion  152  may be viewed by the user (or individual) without the necessity of at least one distinct display portion(s)  154 . 
     The lower the decay time of certain embodiments of the scintillator and/or fluoroscopes (i.e., the shorter the duration of its flashes of fluorescence), the less so-called “dead time” or delay the detector portion will have and the more ionizing events per unit of time it will be able to detect. The excited atoms can thereupon lose some of this excess energy resulting from the dead time by emitting some viewable and/or visible photons. The amount of viewable and/or visible light produced by the scintillator and/or fluoroscope (and thereby the intensity of viewable and/or visible light output by the display portion) can, in certain embodiments, be amplified by a “photomultiplier” that is operationally included in the scintillator and/or fluoroscope. Certain embodiments of the scintillator and/or fluoroscope of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure with respect to  FIG. 20 , can include the Compton scattered X-ray receiving assembly  151  including a combined detector portion  152  and/or display portion  154 . Such combined embodiments of the Compton scattered X-ray receiving assembly  151  can visualize, image, and/or provide information based at least in part on the received photons Compton scattered off the at least the portion of the individual. 
     The scintillator-based and/or fluoroscope-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be useful to provide real-time or near real time Compton scattered X-ray visualization, imaging, or information providing of the at least the portion of the individual. Additionally, certain scintillator-based and/or fluoroscope-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be adjusted to alter subsequent Compton scattered X-ray visualization, imaging, or information providing based on user or controller feedback, or other such aspects. For example, a region that is being visualized, imaged, or have information provided can be modified, angled, magnified, filtered, etc. such as to provide closer examination or Compton scattered X-ray visualization, imaging, or information providing. Certain “scintillator” and/or fluoroscope embodiments of Compton scattered X-ray visualizer, imager, or information provider  100  can be computationally intensive, while other embodiments can view the image directly. By angling the emission of the applied X-ray by the emitter portion  150 , the reception of the scattered X-ray by the Compton scattered X-ray receiving assembly  151  and/or the Compton scattered X-ray receiving assembly  151 , certain ambiguity as to the shape or configurations or aberrations, junctions, dissimilarities, etc. of the matter can be determined. Such angling, etc. can be provided either visually by the user, or by using image process techniques by the visualization, imaging, or information providing controller  97 . 
     Certain scintillator and/or fluoroscope embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be fabricated from, and therefore include, certain materials which can “convert” an X-ray photon to a viewable and/or visible photon. Certain embodiments of scintillators and/or fluoroscopes can amplify a relatively weak photonic X-ray signal such as by utilizing a photomultiplier (typically for each scintillator and/or fluoroscope element). One advantage of amplifying a relatively weak photonic signal is that an adequate depth visualization, image, or provided information can be obtained while subjecting the patient to a much lower dose of X-rays. Certain embodiments of Charge Coupled Devices (CCDs) may be associated with certain embodiments of the at least one detector portion  152  and/or the Compton scattered X-ray receiving assembly  151 . Such embodiments of the Compton scattered X-ray receiving assembly  151  may be referred to in this disclosure as “scintillators” “fluoroscopes”, “film screens”, or “scintillation counters”. Certain embodiments of scintillators and/or fluoroscopes may thereby be considered as direct semiconductor detector portions since they may not be largely computational-based to derive depth visualizations, images, and/or provided information. Certain embodiments of scintillators and/or fluoroscopes can be generated using signal amplification or computer amplification techniques. 
     Certain exemplary embodiments of scintillators and/or fluoroscopes may be configured as semiconductor detector portions  152 , which may be based on converting X-ray photons to electron-hole pairs in the semiconductor, and the electron-hole pairs are thereupon obtained to detect the X-rays. It may be is possible to directly determine the X-ray energy spectrum using so-called called energy dispersive X-ray spectroscopy; and such techniques may additionally be used in small X-ray fluorescence spectrometers. These detector portions are sometimes called “solid detectors”. Medical visualization, imaging, or information providing applications of scintillators and/or fluoroscopes in can rely on the concept that certain semiconductor diodes will thereby produce a small amount of current when placed in an X-ray beam. 
     Certain types of silicon drift detectors (SDDs), such as may be produced by semiconductor fabrication, can provide a relatively high resolving X-ray radiation detection measurement, and thereby be useful for certain embodiments of the Compton scattered X-ray receiving assembly  151 . Certain scintillators and/or fluoroscopes, when combined with semiconductor detectors, can provide indirect detection of X-ray radiation. With the advent of large semiconductor array detectors it has become possible to design detector systems using a scintillator and/or fluoroscope screen to convert from X-rays to viewable and/or visible light which is then converted to electrical signals in an array detector, such as may be used to provide visibility to the human eye. Such signal processing and image processing techniques as filtering, amplifying, resizing, etc. can be applied to scintillator-based and/or fluoroscope-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as to improve Compton scattered X-ray visualization, imaging, or information providing. 
     Certain embodiments of the at least one emitter portion  150  can be dispersive such as to apply X-ray based electromagnetic radiation at the at least the portion of the individual  82 ; such as may thereupon be detected by certain embodiments of the at least one detector portion  152 . As such, certain portions of the Compton scattered X-ray visualizer, imager, or information provider  100  can be associated with or include the emitter portion  150 ; while certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be associated with or include the at least one detector portion  152 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore visualize, image, and/or provide information relating to the at least the portion of the individual that is physically separated from the surface  168  of the at least the portion of the individual. Such visualization, imaging, or information providing can rely on image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques). The quality of such Compton scattered X-ray visualization, imaging, or information providing can improve if the matter being imaged becomes more consistent across the thickness of the imaged portion  352  (e.g., horizontally across the thickness  352  as shown in  FIG. 15 ). As such, as the thickness  352  of the at least one prescribed visualization, imaging, or information providing depth becomes thinner, and its consistency across the thickness becomes more uniform, its depth visualizing, imaging, or information providing consistency generally increases and the associated quality and/or reliability of the visualizing, imaging, or information providing quality generally increases. 
     Selection of a desirable or suitable thickness to image particular matter (e.g. tissue, bones, teeth, etc.) within a particular type of individual may depend, at least in part, on empirical results. For example, scanning skin, muscle, or other tissue across, may be performed in relatively thick slices as compared with depth visualizing, imaging, or information providing bone parts, nodules, or other matter that has a considerable amount of void space or is inconsistent across its imaged thickness. Suitable data, information, visualizations, images, etc. pertaining at least partially to visualization, imaging, or information providing of certain types of matter can be stored in the Compton visualization, imaging, and/or information providing controller  97  (e.g. in a memory, database, or other suitable location), as described with respect to  FIG. 1 . Or alternately, the visualization, imaging, or provided information can be provided as a written reference to the users and/or operators of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as could be accessed and/or set by the user and/or operator. 
     There may be a variety of surgical applications of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are now described with respect to  FIGS. 24 and 25 . The particular suitable applications for certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be dependent upon the frequency, energy, or other characteristics of the applied X-ray photons, as well as the energy level and frequency of the applied X-ray photons can be used for the X-ray Compton scattered X-ray visualization, imaging, or information providing. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , for example, can be particularly suited or configured for treatment and/or examination near the surface  168  such as skin of the at least the portion of the individual  82 , with normal skin being illustrated in  FIG. 24 . By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be particularly suited or configured for treatment and/or examination of at least a portion of the individual; even if the portion of the matter being visualized, imaged, or information provided is spaced a considerable depth distance from a surface into matter of the individual  82  (as illustrated in  FIGS. 18 and 20 ). This may be the case for treating person wishing to examine or locate a particular individual&#39;s organ(s), bone(s), and/or other regions that may be situated subsurface utilizing the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth from the surface  168 . 
     For example, certain Compton scattered X-ray visualizer, imager, or information provider  100  can be utilized to visualize, image, or provide information relating to some matter aberrations, such as to a tumor, tissue contour, etc. (such as may be useful to resect the visualized, imaged, or information provided aberration). Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to control or adjust the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth during resection of a tumor or aberrative matter. This may be accomplished by varying the energy level, frequency, or other characteristics of the applied X-ray photons (which may require reconfiguring of the at least one emitter portion  150 ). Such resection can be accomplished in certain instances by allowing the surgeon to visualize, image, and/or provide information relating to tissue margins of the tumor using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  based on its differential density. The differential density may, in certain instances, be either endogenous to the tissue, or enhanced by a contrast agent which may not otherwise be viewable and/or visible using normal human visual observation. 
     This use of certain Compton scattered X-ray visualizer, imager, or information providers  100  therefore could allow the surgeon to resect a lesion, tumor, etc. while limiting harm and manipulation (or even removal) to adjacent healthy matter or tissue. This can be useful in depth visualizing, imaging, or information providing organs such as the brain that are particularly sensitive to harm, manipulation, or removal of mater. Additionally, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be configured to allow the user (e.g., surgeon or assistant) to view the aberration of the matter at a number of different angles. By allowing the viewing at different angles, etc., it may be easier for the user to appreciate the shape of the aberration, as well as its proximity to adjacent structures such as nerves, blood vessels, or other sensitive or other areas during particular operations or procedures. By limiting such manipulation, contact, or removal or sensitive matter during particular operations and/or procedures, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might likely be configured or designed to perform more radical surgeries or procedures (that might hurt the patient using other imaging techniques) than presently allowable. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information relating to the depth of certain layers of the at least the portion of the individual near the surface  168  (e.g., skin) as described with respect to  FIG. 24 . This may used to examine or visualize, image, and/or provide information relating to the depth of aberrative matter such as tumors in skin as described with respect to  FIG. 25 . With certain conventional imaging techniques, boundaries and/or depth from the surface  168  may not be clear between different types of matter (such as aberrative matter or tissue and normal matter or tissue, different types of cells, etc.). With X-ray based technologies, such as certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , certain types of aberrative matter such as certain cancers, tumors, etc. can be detected as a result of the associated calcification of the matter of the cancers, tumors, etc. 
     For example, it is likely that the calcified aberrative matter or tissue of such aberrative matter as breast cancer nodules in skin will absorb a considerable amount of the X-ray based electromagnetic radiation being applied as compared to the non-cancerous matter. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to indicate outlines, depths, regions, volumes, or other such aberrative matter based on aberrative X-ray and/or photonic characteristics of the aberrative matter as compared to the normal matter (e.g., tissue). Additionally, aberrative matter also may have different contrast enhancing properties from normal matter. An example being a brain tumor can reduce the effectiveness of the blood brain barrier, and thereby absorb certain contrast agents to have visualization, imaging, or information provided characteristics unlike adjacent brain tissue. 
     Certain users using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used to more easily detect or visualize, image, and/or provide information relating to certain aberrative matter, etc. Such ease of detection can allow for more easily location of a position, extent, depth, and/or other aspects of the aberrative matter such as can enhance simplification or effectiveness of examination, removal, and/or treatment thereof. Removal of certain aberrative matter can be performed using certain matter removal techniques that may or may not be performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider, or associated equipment, including but not limited to: surgical cutting techniques, abrasive techniques, ablative techniques (such as laser ablation), etc. 
     Consider that certain surgeons, doctors, veterinarians, dentist, etc. may wish to completely locate and remove all (or at least as much as practicable), or only portion of a particular amount of such aberrations as aberrative or undesired matter interspersed in normal matter or tissue (such as a tumor interspersed in tissue, a cavity interspersed in a tooth, etc.). For example, it may be desired to remove a melanoma (i.e., skin cancer) completely as described with respect to  FIG. 25  (or other skin aberration), while leaving behind as much matter or tissue as practicable. 
     As such, it may be necessary to visualize, image, and/or provide information relating to the aberrative matter (e.g., associated with the melanoma, tumor, etc.) one or more subsequent times such as to determine its precise extent. An initial visualization, imaging, or information providing scan may be useful in locating regions where certain matter aberrations such as melanomas may exist, and subsequent visualization, imaging, and/or information providing scans may be applied to each potential located aberration as to be useful in determining the depth or extent of each aberration. In addition, certain tomography type or volumetric type embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used to map or determine, as accurately as practical or desirable, such aberrations, etc. Certain skin aberrations may include aberrative cells, colonies of cells, growths, or other dissimilar matter as compared to neighboring normal matter, and the aberrative (e.g., cancerous) matter can be based at least partially on the depth to which it has developed. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to determine a depth of dissimilar matter feature within the at least one normal matter. 
     Additionally, a brain tumor might be suitable for being visualized, imaged, or information provided by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , including those embodiments of surgical tools including the Compton scattered X-ray depth visualizer, imager, tactile feedback provider, or information provider  100  that can resect the tumor. As such, the tumor can be resected, with limited adjacent brain tissue that is not infiltrated with tumor effected by the resection. A low grade glioma is one example of a tumors which the Compton scattered X-ray visualizer, imager, or information provider  100  may assist in visually differentiating. 
     If the feature of an aberration or dissimilar mater, such as a tumor, cancerous matter, tooth decay, etc. is not removed completely, the aberration may continue to grow. Such aberrations as cancer or tumors may even grow uncontrollably, and even metastasize. The surgeon may not be able to determine the depth from a visual inspection or even one-time imaging techniques that use certain conventional imagers. An aberrative growth could be quickly examined, and the depth of the aberrative growth could be reliably determined by a skilled user utilizing certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . A dissimilar matter representing an aberration such as a melanoma, if not treated and/or removed in time, may thereby grow to an extent to be dangerous or even fatal. 
     The depth of certain matter aberrations such as melanomas may correspond to their seriousness. For example, if a melanoma has reached below a particular depth  362  as described with respect to  FIG. 25 , then the probability that it has metastasized may increase considerably. As such, there are a variety of medical situations that vital information as to the seriousness of a patient&#39;s condition could be obtained relatively and accurately using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . By utilizing a series of successive images, such aberrations or abnoramlities as melanomas could be examined from a variety of angles, magnifications, and/or positions such as to make certain of their extent. It is likely that at least certain melanomas, breast cancers, other tumors or cancers, etc. can be imaged relative to adjacent matter either based on different densities of the dissimilar matter or alternately using certain contrast agent and/or fluoroscopy techniques. 
     As such,  FIG. 24  shows an example of a partial cross-sectional view of normal matter such as skin; while matter such as skin including a dissimilar matter a melanoma is shown in  FIG. 25 . Normal skin, for example, is typically made up of layers, including the epidermis  370  and the dermis  372 . As illustrated in  FIG. 25 , a skin aberration or tumor such as a melanoma  360  can develop within the skin, and can be measured by a number of quantitative systems, two of which are referred to as “Breslow Depth” and “Clark&#39;s Levels”. Breslow Depth quantifies the top-to-bottom measurement of the melanoma in millimeters, similar to as shown by the arrow  362  in  FIG. 25 . By comparison, Clark&#39;s Levels describe how far the melanoma has extended into the particular layers of the skin. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can therefore be used to determine the characteristics of a melanoma using the Breslow Depth and/or the Clark&#39;s Level. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as can be applied to aberrative matter, such as tumors such as melanomas, are intended to be illustrative in nature but not limiting in scope. Determination of a suitable matter thickness or slice thickness for Compton scattered X-ray visualization, imaging, or information providing may pertain to the likely presence or absence of matter aberrations or other matter abnormalities or matter inconsistencies. 
     As such, by viewing a matter aberration such as a tumor or cancer at a number of angles, positions, magnifications, etc. using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIG. 25 , it is likely that the true extent, depth, and condition of their growth can be determined. Such re-examination or subsequent Compton scattered X-ray visualization, imaging, or information providing of the at least the portion of the individual  82  can be performed at a desired angle, position, etc. Such re-examination can be based or selected, at least in part, on input from the user, the individual, or a controller or computerized portion such as to closely examine those regions of interest under a suitable magnification, angle, position, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can rely on advantages of X-ray technology. X-ray technology provides advantages of being well developed, researched, understood, trusted, etc. X-ray technology can be less expensive than certain other visualization, imaging, or information providing technologies. While certain aspects of X-ray Compton scattered X-ray technology may be less developed than conventional X-ray (e.g., transmissive) technologies, both types of X-ray technologies can be utilized in a variety of medical or non-medical applications including, but not limited to, medical, examination, surgery, geological, security, structural, and other technologies. 
     By allowing subsequent controllable Compton scattered X-ray visualization, imaging, or information providing as is the case with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure, the users such as physicians, surgeons, dentists, etc. can interactively examine the at least the portion of the individual  82 , in a manner as desired. For example, after a desired at least the portion of the individual  82  is located by an initial visualization, imaging, and/or information providing scan, subsequent Compton scattered X-ray visualization, imaging, or information providing scan(s) can further or more closely examine the located portion. With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider, the at least the portion of the individual with at least part of their body part being examined can interactively visualize, image, and/or provide information relating to their condition using subsequent Compton scattered X-ray visualization, imaging, or information providing if the output/display is provided to the at least the portion of the individual  82 . Such subsequent Compton scattered X-ray visualization, imaging, or information providing can be performed on a variety of matter in the at least the portion of the individual. 
     As with a variety of radiographic visualization, imaging, or information providing techniques, and particularly those utilizing X-rays, it is important to consider the dosage effects of certain electromagnetic radiation provided by the Compton scattered X-ray visualizer, imager, or information provider  100  to the at least the portion of the individual and/or the user. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information relating to a series of depth visualizations, images, and/or provided information sequentially, on a real time basis, at a variety of resolutions, or over a large or small portion of the individual. By judicious Compton scattered X-ray visualization, imaging, or information providing using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the radiation doses as applied to the at least the portion of the individual and/or the user can be limited considerably, particularly as compared with many conventional X-ray imaging modalities. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are configured to image by allowing X-rays to pass into, scatter from, and return from a localized organ, matter, etc. Conventional transmissive X-ray devices, by comparison, typically pass through the entire thickness of the at least the portion of the individual being imaged. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured by Compton scattered X-ray visualization, imaging, or information providing a first general area, and thereupon depending upon the initial visualization, image, or provided information. A relatively minor number of visualizations, images, and/or provided information (perhaps localized to small regions) can be examined to consider in considerable degree, for example, one or more regions of interest that have been located by the initial depth interest. Such subsequent depth visualizations, images, and/or provided information may be configured to limit exposure of the at least the portion of the individual or the user to the doses of the original depth visualizations, images, and/or provided information. 
     By allowing subsequent Compton scattered X-ray visualization, imaging, or information providing with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the condition of the at least the portion of the individual may be clearly imaged and/or examined to determine the condition of the at least the portion of the individual. In certain instances, perhaps less drastic treatment (e.g. radiation therapy, chemotherapy) and/or less imaging, visualizing, and/or tests may need to be applied to the at least the portion of the individual based on the more complete or accurate visualization, imaging, or provided information results. Such results may be obtained by (or the relatively precise locating, visualizing, and/or imaging of) certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . In certain instances, perhaps the growths, once clearly examined, can be more accurately treated such as by direct treatment of the relevant location, ablation, etc. 
     A variety of X-ray based electromagnetic radiation (applied, returning/reflected, etc.) can be utilized for Compton scattered X-ray visualization, imaging, or information providing purposes when visualization, imaging, or information providing the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to this disclosure, the emitter portion  150  can apply an applied X-ray  120  to the at least the portion of the individual.  FIG. 18  shows one representative embodiment of the Compton scattered X-ray visualizer, imager, or information provider applying the X-ray (photonic-based electromagnetic radiation) down to the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth within the at least the portion of the individual  82  (e.g., human, shown in cross section). 
     Certain embodiments of the at least one emitter portion  150  can thereby be positioned relative to the at least the portion of the individual  82 , either at least partially internally or at last partially externally to the individual. Certain embodiments of the at least one emitter portion can be configurable to emit the applied X-ray  120  for a controllable depth into the matter of the at least the portion of the individual  82 . The subsequent Compton scattered X-ray (scattered from the applied X-ray) can be detected by the at least one detector portion  152  and/or the at least one display portion. The visualization, imaging, and/or provided information relating to information can thereby be derived at least partially in response to Compton scattered X-ray of the X-ray based electromagnetic radiation. 
     The emitter portion  150  of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to generate at least some of the applied X-ray  120 , that can be applied and/or directed to the at least the portion of the individual  82 . Some of the applied X-ray  120  can be applied by the at least one emitter portion  150  such as to at least partially penetrate into the at least the portion of the individual. During such instances as when penetrating into matter of the at least the portion of the individual  82 , the X-ray based electromagnetic radiation of the applied X-ray can be at least partially deflected, at least partially Compton scattered, and/or at least partially passed through the at least the portion of the individual  82 . Compton scattered X-ray (backscatter, forward scatter, or other) of at least some of the applied X-rays can provide at least some of the Compton scattered X-ray  122  which can be detected by certain embodiments of the at least one detector portion  152 , and/or the at least one Compton scattered X-ray receiving assembly  151 . 
     Certain examples of the other matter that can effect the Compton scattered X-ray can include, for example: tissue, bones, portions of bones, metal, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured for Compton scattered X-ray visualization, imaging, or information providing matter not normally associated with X-ray Compton scattered X-ray visualization, imaging, or information providing. Such would be the case with locating interfaces between two different types of matter including, but not limited to: “normal” or “regular” opaque matter (such as tissue), as compared with other aberration matter. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to combine visualization, imaging, or information providing at least partially by combining information obtained from the Compton scattered X-ray visualizer, imager, or information provider  100  with image information from another source (e.g., MRI, conventional X-rays, other Compton scattering-based systems or portions thereof, other embodiments of the Compton scattered x-ray visualizer, imager, or information provider  100 , etc.). Such combinations may take the form or function, for example, of depth, position, varying depth visualizing, imaging, or information providing modalities, etc.; and may include previously gathered depth visualizing information. 
     Certain of such combined embodiments of Compton scattered X-ray visualizer, imager, or information provider  100  can be useful for instance where the imaging capabilities of the Compton scattered X-ray visualizer, imager, or information provider  100  may be more limited such as to produce a real-time visualization, imaging, or information providing, and thereupon integrating more detail imaging from other imaging modalities. Although certain aspects of the visualization, images, or provided information of particular matter such as tissue, organs, bones, or other portions of the individuals may not precisely match between certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  and the other conventional visualization, imaging, or information providing modalities, it is likely that each modality could be expected to be particularly useful for particular applications, illnesses, injuries, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may also be configured as to be able to visualize, image, or provide information at a suitable rate considering the matter being imaged and/or the ability of the user to be able to view the distortions. There might be a variety of distortions of the matter which may be particularly useful to visualize, image, or provide information. For example, certain surgeons might be particularly interested in considering the rate at which the heart beating causes deformation of the heart muscle, or alters blood flow through portions of the heart such as the aorta, valves, etc. By comparison, other surgeons may be interested in considering somewhat slower motion of their patients, such as how changes in the body position (e.g., leg or arm position) may be reflected in variation in the associated skeletal bones between successive depth visualization, imaging, or providing information. Certain dentists or orthodontists might be interested in how movement of the jaw can be reflected by changes in the bite of the teeth of their patients. 
     As described with respect to  FIG. 18 , certain embodiments of the emitter portion  150  can apply at least one applied X-ray  120  at a desired, or controllable, angle. The depth visualizing, imaging, or information providing angle of the applied X-ray radiation may range from almost parallel, but still incident, to a surface  168  of the at least the portion of the individual  82 , to substantially perpendicular to the surface  168  of the at least the portion of the individual  82 , and any angle there between). The characteristics of the applied X-ray may include, but are not limited to, a suitable and/or desired position, power, frequency, energy level, duration, as well as a variety of other such characteristics. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to include at least one detector portion  152  and/or display portion  154  that can be operable to be at least partially inserted into the at least the portion of the individual. Such configurations can be used to receive at least one Compton scattered X-ray that has been Compton scattered in an at least one opaque matter of the at least the portion of the individual. Certain embodiments of the detector portion can be configured to be adjustable, alignable, scannable, or otherwise modifiable; and may include such scopes as endoscopes that may alternately be inserted through insertion or normally open opening of the individual as is generally understood by the use of an endoscope. 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  might preferably be configured as combined detector portion/display portions as described in this disclosure, such that the visualizer, imager, and/or information provider might suitably change as the user moves their vantage point, etc. relative to the at least the portion of the individual. It may be desired to reduce or limit the involved computation associated with depth visualizing, imaging, or information providing. By comparison, those embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  involved in depth visualizing, imaging, or information providing relatively deep into the at least the portion of the individual may include the distinct detector portions and display portions. Additionally, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied in the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth relatively near the surface  168 . Recall that such image combining may utilize image subtraction, time of flight, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques. Such distinct detector portions and display portions may be configured to computationally differentiate images, visualizations, information, etc. using certain image information. Additionally, such computationally complex visualization, imaging, or information providing displays as time of flight embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  (or high resolution display portions) may benefit from the distinct detector portions and display portions, which may also simplify the associated image processing. These design choices are intended to be illustrative in nature, but not limiting in scope. 
     Certain embodiments of the detector portion  152  may be situated within the at least the portion of the individual  82 , adjacent to the at least the portion of the individual  82 , or external to the at least the portion of the individual  82 . Either one detector portion  152 , or a plurality of detector portions, may be provided either within the at least the portion of the individual  82 , adjacent to the at least the portion of the individual  82 , and/or external to the at least the portion of the individual  82 . 
     Within this disclosure, certain embodiments of the at least one display portion  154  can be configured to display the X-ray based electromagnetic radiation such as it has at least been partially received from the at least the portion of the individual  82  by the at least one detector portion. As such, certain embodiments of the at least one display portion  154  can be configured to display X-ray illumination that can be Compton scattered at least partially from the at least the portion of the individual  82 . Such Compton scattered X-ray illumination can be based on the Compton scattered X-ray based electromagnetic radiation that can be detected by the at least one detector portion  152 . 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  can include a variety of the at least one display portion  154 . Certain embodiments of the display portion  154  can take a variety of forms that can include, but are not limited to: a cathode ray tube (CRT) display portion, a liquid crystal display portion (LCD) display portion, a personal display or information provider portion (configured to display to one person), a glasses-based display portion, a group display or information provider portion (that can display depth visualizations, images, and/or provided information to more than one person), a plasma display portion, a medical display portion, a computer display portion, a personal display assistant (PDA) display portion, or such other displays that can at least partially provide a display of at least the portion of the individual based at least in part on the Compton scattered X-rays  122 . 
     The selection as to whether the Compton scattered X-ray receiving assembly  151  includes distinct detector portions and display portions, or combined detector portion/display portions can be based at least partially based on functionality and/or desired computation. For example, certain Compton scattered X-ray visualization, imaging, or information providing applications involving depth imaging, visualizing, or providing information from the surface  168  to the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth. 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  may be configured as surgeon&#39;s glasses, or other configuration, as illustrated in  FIG. 26 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as personal devices, which can thereby be used primarily by one person. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used as group devices such as can be used by two or more persons or users. Particularly,  FIG. 26  shows one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  including an embodiment of the at least one display portion  154  configured as a personal display (in this instance, surgeon glasses, dentist glasses, veterinarian glasses, etc.), as described in this disclosure. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured as augmented vision glasses. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize glasses, such as can be worn by surgeons in which at least a portion of the glasses can be configured as a display, such display portion could be viewed by the user. Certain embodiments of the visualizing, imaging, or information provided as provided by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be optically aligned to the user. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be configured as an X-ray backscatter device is used to deliver a real-time 2D or 3D depth visualization, image, or information to the surgeon. The depth visualizations or images can be presented to the surgeon by means of an external monitor, head-mounted display, or stereoscopic projection. The surgeon can select the depth (from millimeters to substantially through the visualized, imaged, or have information provided portion of the individual  82 ) at which the visualization, image, or provided information is taken, captured, etc.; the selected depth can be targeted by tuning the intensity, energy level, or frequency of the X-ray photons in the X-ray beam. 
     There may be a variety of configurations and/or utilizations of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . For example, certain personalized embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can present depth visualization, image, or information to at least one person particularly associated with the Compton scattered X-ray visualizer, imager, or information provider, similar to as described with respect to  FIG. 26 . Certain personalized embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be worn as personal devices, such that each of the at least the portion of the individual  82  can obtain the depth visualization, image, or information of the at least the portion of the individual  82  in a manner similar to glasses. For instance, in the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIG. 26 , the emitter portion  150  can be situated proximate the glasses-based embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  (e.g., on the frame); adhered to the user at a remote location from the glasses (e.g., on cloth, clothes, fabric, metal, or other material); or alternatively situated at a remote location from the user. 
     Certain embodiments of the detector portion  152  of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 26 , can thereby be described as surgeons&#39; glasses. The term “surgeon&#39;s glasses” is intended to be illustrative and not limiting since these devices can be worn by the user and illustrate visualizations and/or images, as well as provide information, to the user or other person. Certain surgical glass embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may or may not contain optical glasses at all. Certain surgical glasses are understood to perhaps include an additional display portion (which may function as typical optical glasses) such as can be viewed by a surgeon, or alternatively may be provided as only a frame without the optical glasses. Certain embodiments of the surgical glasses, can include, for example, at least one liquid crystal display (LCD), at least one light emitting diode (LED) or an embodiment of the Compton scattered X-ray receiving assembly  151  that can be secured by a variety of mechanisms to nearby are to the user, such as can be viewed by the user. With surgeon&#39;s glasses, a variety of display portions can be provided to surgeons, etc. through a portion of glasses, while other portions of the glasses allow the surgeon to see during the operation. 
     By comparison, a number of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could include at least one display portion  154  can be configured as a group display or information provider portion. For example,  FIG. 27  illustrates an instance in which a number of users could view selected portion(s) of the individual through a group display  154 , as described in this disclosure such as could be viewed by a number of users. For instance, the Compton scattered X-ray visualizer, imager, or information provider  100  can include an LCD display portion, a CRT display portion, a television display portion, a medical display portion, or other applicable embodiments of the Compton scattered X-ray visualizer, imager, or information provider. 
     Certain of the applied X-ray  120 , that are generated and/or applied to the at least the portion of the individual  82  by certain embodiments of the emitter portion  150 , may thereupon after at least partially passing into the at least the portion of the individual  82  be subsequently Compton scattered and/or deflected. Such Compton scattering and/or deflection can thereupon be detected by the at least one detector portion  152 , as described with respect to  FIG. 1 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , can include a considerable number of detector portions  152  positioned, for example, around an operation or examination room in which the individual  82  is situated. The particular arrangement of a number of the emitter portions  150  is largely considered to be a design choice. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be adjustable, tunable, and/or controllable. Such adjustability, tunability, and/or controllability can be used to adjust the energy level or frequency of the X-ray photons of the applied X-rays; and thereby affect the depth of Compton scattered X-ray visualization, imaging, or information providing, into the at least some matter of the at least the portion of the individual. Certain external embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured to be non-contact, with an emitter portion  150  probe and/or detector portion  152  probe that does not contact the surface  168  of the matter of the at least the portion of the individual. Other embodiments adjustable, tunable, and/or controllable do permit contact of the emitter portion  150  probe and/or detector portion  152  probe with the matter of the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide a number of modalities of depth visualizing, imaging, or information providing (traditional X-ray images, Compton scattered X-ray visualization, imaging, or information providing, etc.) including, but not limited to, density and elemental depth visualizing, imaging, or information providing mode. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to provide considerable contrast, and thereby may be less dependent on such variables as user skill in depth visualizing, imaging, or information providing, etc. 
     Different versions of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to combine image information with that being performed by different imagers that can produce images in one or a variety of different formats and configurations. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied externally or internally, such as described relative to certain locations in this disclosure. Certain external configurations of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize either full-body tomography imaging enclosures or partial body tomography imaging enclosures, similar to as generally used during MRIs, CAT scans, PET scans, etc. By comparison, certain embodiments of the at least one emitter portion(s)  151  for certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be positioned around the room where the individual is situated. Such configurations can be configured to improve the application of the applied X-rays  120  towards the at least the portion of the individual being imaged. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider could used to obtain a CAT-grade or PET-grade tomography scan, based at least in part on the configuration and structure of the at least one emitter portions  150  and/or the at least one Compton scattered X-ray receiving assembly  151 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured to provide depth visualizing, imaging, or information providing flexibility, as well as to conform to the at least the portion of the individual being imaged as described with respect to  FIG. 28 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be attached to a flexible securing member (perhaps even being attached to the individual using belts, Velcro, straps, or some other known fastener), such as can be used to limit relative displacements between the visualizing components and the at least the portion of the individual. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as a fabric or jointed sleeve that can be at least partially tied to, worn by, or attached to surround the at least part of the patient, as described with respect to  FIG. 28 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be embedded in, or attached to, clothing, fabric, or other material that can be made distinctly for each individual, or can be used by a number of individuals. Such flexible attachment members may be especially desirable for monitoring or examining, or otherwise visualizing, imaging, or providing information relating to particular portion or organ of the individual, such as the heart, brain, or other organs, tissue, or other matter. 
     For example, at least portions of the Compton scattered X-ray visualizer, imager, or information provider  100  may be applied to securing elements which can be maintained or secured with respect to the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be flexibly applied to a more extensive portion of the individual such as the torso; or a smaller portion of the individual such as an arm, leg, finger, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can at least partially include a sleeve or other flexible portion that at least partially be affixed to and/or surrounds the individual. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to limit relative motion between at least one portion of the at least one Compton scattered X-ray receiving assembly  151  relative to the at least the portion of the individual. By limiting the relative motion between the at least one emitter portion  150  and/or the at least Compton scattered X-ray receiving assembly  151  with respect to the at least the portion of the individual, a number of aspects of depth visualizing, imaging, or information providing can be improved, such as clarity and perhaps improved resolution. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to act as a shield to limit transmission of X-rays outside of the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  (particularly those flexible configurations as described with respect to  FIG. 28 ) can be configured to include X-ray shielding material to shield users and/or individuals from the X-rays. Consider that the Compton scattered X-ray visualizer, imager, or information provider  100  as described in this disclosure could include an X-ray shielding material such as could limit excessive stray X-rays from passing away towards the user such as a doctor, veterinarian, etc. Such users may be exposed to a higher total dosage of X-rays after depth visualizing, imaging, or information providing a number of individual patients, etc., as compared with the individuals who are seldom imaged. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may also shield at least some of the X-rays from passing to the at least the portion of the individual. In certain instances, such shielding may be removable, replaceable, and/or shiftable such as to shield at least certain portions of the individual at one or more locations depending on which emitter portions  150  and/or detector portions  152  are being utilized. 
     Certain embodiments of the at least one emitter portion  150  and/or the at least one detector portion  152  can thereby be configured as a hand-held and positional device as described with respect to  FIG. 29  such as can be positioned and/or used by the user, the individual, or another person. Is envisioned that at least portions of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured similar to a computer mouse (e.g., in dimension and/or position), such as to allow a user to position the device from a useful (and/or non-obstructive) user-selectable vantage point relative to the individual. Certain hand-held devices can transmit data to other detector or display devices, such as can be displayed over displays, glasses, plasma, or a variety of at least portions of certain embodiments of the Compton scattered X-ray receiving assembly  151 . 
     Certain portable or repositionable embodiments of at least portions of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize wireless and/or wired-based communications relative to other controller and/or computer portions associated therewith to effect data transfer, image transfer, etc. Alternately, certain embodiments of the constant scattered X-ray visualized, imaged, or information provided  100  can include the display and/or simulator as to provide for visualization, imaging, and/or provide information directly there from. Certain user-selectable positionable Compton scattered X-ray visualizer, imager, or information provider  100  could be securable in position by some securement or locking structure relative to the matter of the at least the portion of the individual. Such securement or fastener techniques can be used to limit excessive motion of the Compton scattered X-ray visualizer, imager, or information provider  100  relative to the at least the portion of the individual and/or improve depth visualizing, imaging, or information providing capability or quality of the Compton scattered X-ray visualizer, imager, or information provider. As such, the emitter portion could be positioned and located as desired. Certain embodiments of the emitter portion  150  could include a mount that might hold the emitter portion  150  in position, such as might limit the displacements of the emitter portion to improve the Compton scattered X-ray visualization, imaging, or information providing capabilities of the Compton scattered X-ray visualizer, imager, or information provider  100 . By providing a hand-held and/or positionable device, certain users can obtain a desired depth visualization or image at a desired location without while the remainder of the user remains in a desired viewing or other position and/or location. 
     With certain hand-held positionable embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , relatively quick feedback rates may be particularly desirable for Compton scattered X-ray visualization, imaging, or information providing. Certain hand-held, positionable, or movable devices may also be useful in providing Compton scattered X-ray visualization, imaging, or information providing at a variety of locations and/or angles of the individual such as may be controlled or adjusted by the user, the individual, a machine (e.g., robot), or an other person. 
     The emitter portion  150  and/or detector portion  152  can thereby be configured as a remote device, or even a movable device such as can be a hand-held device (perhaps similar in size or shape as a computer mouse, or a digital camera as described with respect to  FIG. 29 ). Such movable, frame secured, securable, or other embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby provide applied X-rays and/or receive scattered X-rays from desired or controllable positionable locations. For instance, a doctor could position certain embodiments of the emitter portion adjacent the at least the portion of the individual  82 , such that particular subsurface regions of the at least the portion of the individual can be illuminated by or receive the X-ray based electromagnetic radiation adjacent the at least the portion of the individual  82 . Such controllability or positionability of visualizing, imaging, or information providing can be performed in a similar manner as a user of a flashlight might apply the flashlight to certain locations to optionally illuminate particular regions at which the flashlight is directed. Similarly, a physician might position the at least one detector portion  152  in close proximity to the portion(s) of the individual being visualized, imaged, or information provided. By comparison, certain embodiments of the emitter portion can be configured as applying a relatively disperse X-ray source that can generally apply X-rays to against large regions (or at least regions of interest) of the at least the portion of the individual  82 . Different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  (i.e., surgeon positioning and/or region of room filling embodiments of the at least one emitter portion  150 , etc.) can be used separately or in combination, and are intended to be illustrative in nature but not limiting in scope. 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  and/or the display can be positioned in close proximity to the at least the portion of the individual, as described with respect to  FIG. 30 . For example, the at least one Compton scattered X-ray receiving assembly  151  that is Compton scattered X-ray visualization, imaging, or information providing a bone in a forearm may be positioned adjacent the forearm, perhaps even in a position that may be viewable by the user and/or the user. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize at least one fiducial  1052  to assist in locating the visualized, imaged, or information provided portion. The embodiments of the Compton scattered X-ray receiving assembly  151  as described with respect to  FIG. 31  can be configured for depth visualizing, imaging, or information providing relatively deep portions of the individual, such as skeletal systems, organs, certain internal blood vessels, etc. It is likely that such embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that act deep into the matter of the individual can also apply the applied X-rays including at least some X-ray photons having sufficient energy level that can pass deep into the individual. Such deep visualizing, imaging, or information providing would likely utilize the image processing techniques as described with respect to  FIGS. 18 and 19 , for example. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIGS. 30 and 31 , can include a framework  3010  and be configured such as to contain at least the Compton scattered X-ray receiving assembly  151  (not shown in these figures). Certain embodiments of the framework can be used to be positioned by the user, or secured by a securing device (rigid frame, arm, flexible belt, strap, or other). 
     Certain embodiments of the entire Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIG. 1  can therefore be configured as a single unitary member utilizing similar technology as is known in graphical user interface (GUI), display, and controller technology such as to integrate all the portions of devices into combined units. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as distinct units, only certain ones of which may include their distinct framework  3010  if desired, or practicable. There are a variety of potential advantages to frameworks which include, but are not limited to, allowing a user to hold or providing a securement point (certain ones of which can be adjusted and controlled) to at least certain portions of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Certain conventional transmissive X-rays can image three-dimensional matter across the extent of the portion of the person to a two-dimensional image. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , by imaging a two-dimensional slice of the individual (e.g., imaging through the bone), might be particularly useful in visualizing, imaging, or providing information pertaining to the individual for orthopedics, knees, bones, joints, organs, and other structural aspects of the individual. 
     Certain embodiments of the Compton scattered x-ray visualizer, imager, or information provider  100  can be configured to operate based at least in part on tomography. Tomography can be based, at least partially, on obtaining at least one material characterizing distribution function. Within this disclosure, the material characterizing distribution function can be considered as a measurement of electron density, which more or less corresponds to the density of the matter. As such, a variety of visualizations, images, or provided information of at least some matter of at least the portion of the individual based at least upon the material characterizing distribution function. Conventional tomography, such as CAT scan, PET scan, etc. may rely upon obtaining at least some type of distribution function. Those electrons of the outer shells of the matter, thereby are loosely held to the molecule, in such a manner to quantifiably correspond largely to the material characterizing distribution function. By comparison, those electrons of the inner shell of the matter thereby are more securely held to the molecule, and therefore correspond to a lesser degree to the material characterizing distribution function. 
     Certain embodiments of the Compton scattered X-ray receiving assembly  151  can receive a number of Compton scattered X-ray in such a manner that there exists a number of uncertainties as to certain characteristics (e.g., in density, mass, structure, component, etc.) of the matter. For example, a particular Compton scattered x-ray receiving assembly  151  that receives scattered X-rays from a specific angle and/or position may receive a large number of scattered x-rays that correspond to that angle and/or position, corresponding to the material characterizing distribution function. They may be, for example, no way to differentiate between scattered X-rays from a number of different depths that correspond to a given angle and/or position within the at least some matter of the at least some portion of the individual, upon consideration of the material characterizing distribution function. Conventional tomography can similarly utilizes a material characterizing distribution function. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can capture a visualization, image, or provided information based on a number of material characterizing distribution function that are obtained from a number of positions, angles, etc. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize the material characterizing distribution function obtained when applying an applied X-ray substantially through a considerable portion of the individual that are forward scattered, similar to as described relative to  FIG. 5 , for example, and other locations through this disclosure. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize the material characterizing distribution function obtained when applying an applied X-ray substantially through a considerable portion of the individual that can thereupon be back scattered, forward scattered, or otherwise Compton scattered similar to as described relative to  FIG. 4 , for example, and other locations through this disclosure. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can differentiate between scattered X-rays from different scattering locations and/or angles, based at least partially on tomographic/volumatric considerations. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can differentiate between scattered X-rays from different energy levels, based at least partially on tomographic considerations. 
     The embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are secured to the at least the portion of the individual, using a sleeve or other such mechanism, will likely be preferred by individuals undergoing imaging as compared with certain MRI images, CAT scans, tomography imagers, and/or other conventional imagers in which the patient is expected to remain substantially motionless. In addition, certain conventional tomography imaging techniques require positioning of the individual in a claustrophobic tube during the relatively extended duration. 
     Certain types of tomography imagers (both conventional and included as certain embodiments of Compton scattered X-ray visualizer, imager, or information provider  100 ), may tend to be quite computer-software and processor intensive. Much of the work by the computer software, hardware, or firmware is associated with repositioning, focusing, zooming, angling, refreshing, and other controlling and adjusting aspects of the displayed visualization, image, or provided information. Certain of the depth visualizing, imaging, or information providing components of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be indexed relative to the portion of the individual. Such indexing can be performed such that if a region of interest (e.g., a cancer node) is located, the location can be determined relative to the Compton scattered X-ray visualizer, imager, or information provider  100 , such as by longitude or latitude markings on the sleeve in certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain instances of such visualization, imaging, or information providing can be provided on a real time (or near real time) basis. 
     A considerable portion of this disclosure describes applying Compton scattered X-ray visualizer, imager, or information providers to image to locate, analyze, and/or treat a variety of aberrations such as cancers. It is also envisioned that a number of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to a variety of surgical, medical examination, medical diagnosis, medical forensics, autopsies and other such applications. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may visualize, image, and/or provide information relating to blood that can be configured to provide high contrast with this technique since it has iron and backscatters considerably. 
     As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider may be particularly appropriate for brain Compton scattered X-ray visualization, imaging, or information providing and/or surgery, heart Compton scattered X-ray visualization, imaging, or information providing and/or surgery, lung Compton scattered X-ray visualization, imaging, or information providing and/or surgery, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured to examine aberrations of such dissimilar matter such as calcium concentration of portions of matter for Compton scattered X-ray visualization, imaging, or information providing or examination for breast tumors, iodine for thyroid Compton scattered X-ray visualization, imaging, or information providing or examination. Additionally, certain contrast agents may be used to enhance the contrast for Compton scattered X-ray visualization, imaging, or information providing, for example iodine in blood vessels. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include a relatively weak powered X-ray based emitter portion  150 , such that much of the X-rays generated therefrom may not be transmitted through the at least the portion of the individual. Such relatively weak powered X-ray emitter portions  150  may be desirable since they limit the dosage being applied to the at least the portion of the individual, as well as others near the individual such as the user. 
     There are a number of Compton scattered X-ray visualization, imaging, or information providing techniques that can be utilized by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , each of which should consider limiting the overall dosage of X-rays being applied to the at least the portion of the individual and/or other persons. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to operate on a temporal/positional reflective basis. This may, depending on context, be considered as Compton scattered X-ray visualization, imaging, or information providing at a rate sufficient to indicate accurately the current position of the portion of the individual  82  undergoing Compton scattered X-ray visualization, imaging, or information providing (considering the intended purpose of the at least one visualization, image, or provided information). 
     Real time depth imaging, visualizing, or information providing, and near real time depth imaging, visualizing, or information providing may be considered as one embodiment of temporal/positional reflective depth visualizing, imaging, or information providing. As such, temporal/positional visualization, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can involve updating of Compton scattered X-ray visualization, imaging, or information providing within such a duration as to accurately reflect a state of the at least the portion of the individual  82 . By using certain types of temporal/positional reflective visualization, imaging, or information providing using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider, certain users may be able to locate a region, organ, etc. within the at least the portion of the individual either manually or using a tool. Examples of such tools as described in this disclosure can include, but are not limited to, an endoscope attachment, a tactile feedback provider, an attachment to a framework, etc. 
     As such, certain embodiments of the X-ray Compton scattered X-ray information can be utilized or operated by the user and/or the individual on a substantially temporal/positional reflective basis. At the time of operation, Compton scattered X-ray visualization, imaging, or information providing and/or visualize, image, and/or provide information updating can be performed at a substantially temporal/positional reflective basis. Alternatively, certain Compton scattered X-ray visualization, imaging, or information providing and/or visualize, image, and/or provide information updating could be performed sequentially a number of times, or only one or more times using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     A number of illustrative but not limiting applications of temporal depth visualizing, imaging, or information providing by certain embodiments of the subcutaneous Compton scattered X-ray visualizer, imager, or information provider  100  are now described. One application of temporal depth visualizing, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could include functional brain depth visualizing, imaging, or information providing or functional tomography, in which certain regions of brain activation may be reflected with increases in blood flow. This type of depth visualizing, imaging, or information providing could be used during brain surgeries to detect an area associated with a given cognitive action or sensory stimulation by monitoring or detecting alterations in blood flow. Another application of temporal depth visualizing, imaging, or information providing by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  would include vascular surgery. Whether the vascular surgery be for clipping an aneurysm or creating a vascular graft, one could use the subcutaneous Compton scattered X-ray visualizer, imager, or information provider  100  to detect alterations in blood flow in the brain, heart, liver, or other organ, tissue, or region of the individual. 
     Yet another depth visualizing, imaging, or information providing application of certain embodiments of the subcutaneous Compton scattered X-ray visualizer, imager, or information provider  100  could include implantation of orthopedic instrumentation. A user such as a surgeon could image, examine, and/or utilized the implant during installation to ensure that it is being installed properly. As such, the user could insure the implant is not being positioned are located in properly or in the wrong place during attachment or securement. Dentists could similarly image, examine, and/or utilize images relating to their dental work. An example of such installation-based Compton scattered X-ray visualization, imaging, or information providing might include installing a pedicle screw to be used in a spinal construct and/or plate. Certain embodiments of the subcutaneous Compton scattered X-ray visualizer, imager, or information provider  100  may be used to ensure the screw has not breached and gone into the spinal canal, or alternately exited to hit a blood vessel, a nerve root, or another sensitive region. Certain embodiments of the subcutaneous Compton scattered X-ray visualizer, imager, or information provider  100  could thereby help watch the implant placement progression. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to different individuals such as a variety of humans of different conditions, sexes, ages (e.g., a human adult, child, or embryo), etc. Additionally, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to at least one other non-human individuals  82  including, but not limited to: at least one animal (domestic, wildlife, livestock as described with respect to  FIGS. 32 and 33 ), at least one organism (natural or synthetic, such as can be visualized, imaged, or have information provided for medical, scientific, clinical or other purposes), at least one plant, etc. By Compton scattered X-ray visualization, imaging, or information providing animals such as pets, wild animals, or livestock, for example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can obtain useful information thereabout, without the necessity of the user having to come into close contact, or only limited contact, with the animal. Such users who often have to come in contact with animals might include, but are not limited to: veterinarian, wildlife managers, zookeepers, other people associated with wild or domestic animals, etc. Such close contact is also possible during use by certain Compton scattered X-ray visualization, imaging, or information providing embodiments. In addition, such Compton scattered X-ray visualization, imaging, or information providing can be done relatively routinely, or in a non-evident manner, such as to make scanning the animals, or a relatively large number of animals, relatively easy without them necessarily being aware of the depth visualizing, imaging, or information providing. Such depth visualizing, imaging, or information providing of certain animals may preferably be performed in a manner that reduces the animal&#39;s awareness that anything unusual is occurring, such as may easily be accomplished using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , 
     The above-mentioned components or embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1  as well as in other locations in this disclosure, could be distributed or operated outside, in a forest, etc. Such configurations could allow Compton scattered X-ray visualization, imaging, or information providing of wild animals (perhaps controlled and/or adjusted by remote control), livestock, fish, etc. Such embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be useful in detecting illnesses, injuries, etc. in wildlife, whales, dolphins, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to animals such pets, livestock, wild animals, aquatic animals and fish, etc. as described with respect to  FIGS. 32 and 33 , for example. Since animals do not understand conventional imaging or other medical processes, they may be difficult to handle or become agitated or confused under certain conventional imaging circumstances. As such, it may be very difficult to image portions of animals to determine their condition using certain conventional imagers. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be applied in such manner such as the animal may not even be aware of the ongoing Compton scattered X-ray visualization, imaging, or information providing. Veterinarians could utilize certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to obtain considerable Compton scattered X-ray visualization, imaging, or information providing information previously unobtainable while keeping a safe distance from uncooperative, uncertain, or dangerous animals. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be applied to livestock, such as may be situated in a corral or even a field as described with respect to  FIG. 33 . Such livestock embodiments of the Compton scattered X-ray visualizer, imager, or information provider may be able to scan them for certain illnesses, conditions, sicknesses, etc. (e.g., mad cow disease). Certain users of the Compton scattered X-ray visualizer, imager, or information provider  100  could be characterized by relative speed, limited expense, reliability, and effectiveness. 
     As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information of a wide variety of individuals from the surface  168  of the at least the portion of the individual down to the within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth. As described herein, the surface could be internal and/or external to the individual. The particular Compton scattered X-ray visualization, imaging, or information providing modality being utilized should be configured based on the matter, region, structure, and other characteristics, of the at least the portion of the individual as well as the condition of the at least the portion of the individual, etc. 
     Compton scattered X-ray visualization, imaging, or information providing of distinct matter relatively can be based at least partially on different X-ray based characteristics of the distinct matter, the junction location of the different matters, etc. One X-ray characteristic can be based, at least partially, on X-ray absorbance differences between different types of matter. Bones, bone fragments, etc. when being exposed to transmissive X-rays are generally understood to absorb more X-ray based electromagnetic radiation (e.g., X-ray photons) than softer human matter (such as skin, tissue, muscle, blood, bodily fluid, etc.), for example. Even with X-ray Compton scattered X-ray, such as utilized by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the bone or bone fragments would be expected to be more dense, and would be expected to absorb more X-rays of certain frequencies/energy levels than other matter such as tissue. As such, certain matter will scatter a greater percentage of the applied or applied X-rays than bone or bone fragments, which will absorb a greater percentage of X-rays. 
     Similarly, each type of matter such as tissue, muscle, bones, fat, etc. should have distinct X-ray characteristics that can be imaged directly using Compton scattered X-ray techniques, and/or by using certain particular contrast agents or fluoroscopy using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider. Another X-ray characteristic can be based, at least partially, on Compton scattered X-ray or reflectance differences between different types of matter. Yet another X-ray characteristic can be based, at least partially, on a ratio of photons transmission compared to photons return between different types of matter. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize a single applied X-ray beam  120  during Compton scattered X-ray visualization, imaging, or information providing such as can be provided by at least one emitter portion  150 , as described in this disclosure. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can utilize multiple applied X-ray beams  120  which may at least partially intersect with each other during Compton scattered X-ray visualization, imaging, or information providing such as can be provided by the at least one emitter portion  150 , as described in this disclosure. With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the intersection of the multiple applied X-rays  120  can be applied at a location that may be desired to be visualized, imaged, or information provided, such as at a particular depth, etc. 
     With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the intersection location of the multiple applied X-rays can be controllably moved to a desired location such as may be controlled by the user of certain embodiments of the subsurface Compton scattered X-ray visualization, imaging, or information providing controller  97  as described in this disclosure with respect to  FIG. 1 . Alternately, such movement of the intersection can effect a scan, similar to a raster scan such as is generally known by those skilled with displays. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured to provide a variety of different depth visualizations, images, and/or provided information depending on the Compton scattered X-ray visualization, imaging, or information providing techniques. For instance, by Compton scattered X-ray visualization, imaging, or information providing, certain individuals could be visualized, imaged, or have information provided in a manner appearing similar to (but perhaps having different resolution or characteristics from) imaging by conventional X-ray, fluoroscopy, MRI, CAT scans, or other Compton scattered X-ray visualization, imaging, or information providing modalities. 
     One aspect of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  is that relatively small depth visualizations, images, and/or provided information can be captured, displayed, analyzed, and if desired recaptured without waiting for durations associated with processing, or developing, the images are visualizations for a larger region. In certain circumstances, the visualizing, imaging, and/or providing information can be performed without having to wait for processing or developing, and the necessity of having to move or reposition the patient. During certain conventional imaging techniques, the at least the portion of the individual must remain virtually motionless during the conventional imaging process to maintain the image quality. Additionally, certain conventional image techniques take a considerable duration to capture, develop, process, display, etc. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can capture and/or display certain localized or shallow depth visualizations, images, and/or provided information relatively quickly. As such, the user such as the physician, veterinarian, dentist, or other user can quickly examine the visualize, image, and/or provide information and/or obtain additional subsequent depth visualizations, images, and/or provided information that show desired features, positions, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may not require maintaining the at least the portion of the individual nearly motionless in an encircling enclosure or tunnel, such as with CT scans, PET scans, or MRI. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might involve a change in Compton scattered X-ray visualization, imaging, or information providing techniques by the users, surgeons, etc., but would likely not diminish Compton scattered X-ray visualization, imaging, or information providing capabilities or resolution as compared with other conventional imaging techniques. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured such that the at least one matter associated with the at least the portion of the individual  82 . For example, the matter of the portion of the human can include at least some, or combination of: flesh, muscle, fat, tissue, bone, teeth, blood, fluids, or other such matter. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information relating to not only matter in general, but also different types of matter and junctions between different types of matter. Such Compton scattered X-ray visualization, imaging, or information providing matter can be performed at the range of resolutions as described in this disclosure, and may at least partially rely on additional agents, components, etc. such as may enhance Compton scattered X-ray visualization, imaging, or information providing. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow physicians a number of opportunities to detect certain types of distinct matter, such as tumors or cancer that may be situated in a region of generally normal matter. Certain Compton scattered X-ray visualization, imaging, or information providing modalities may be more successful to detect certain types of cancers as compared with certain visualizers, imagers, or have information providers. It may therefore be useful to provide a Compton scattered X-ray visualization, imaging, or information providing modality that can detect at least one or a considerable number and types of cancers, tumors, and/or other matter aberrations as described in this disclosure. For instance, certain Compton scattered X-ray visualization, imaging, or information providing modalities may not detect certain cancers or other matter aberrations, while other Compton scattered X-ray visualization, imaging, or information providing modalities (perhaps including certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 ) may detect the cancers or other matter aberrations. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured or designed to detect at least one of a variety of cancers or tumors such as, but not limited to: breast cancer, skin cancer, colon cancer, bladder cancer, prostate cancer, etc. Such cancer cells or tumors may be situated in the matter at a location that certain conventional imagers may not be able to image, or may be expensive to image well. Certain cancers, such as certain breast cancer and certain melanomas, may be characterized by calcium nodules, which may be difficult be detect using a variety of conventional imaging techniques and/or devices. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be well suited to visualize, image, and/or provide information relating to a variety of cancer and/or tumors. Certain tumors or cancers may exhibit angiogenesis that allow depth visualizing, imaging, or information providing by certain Compton scattered X-ray visualizer, imager, or information providers  100 . The blood vessel of the patient individual nearby the cancer or tumor may be grown to allow for an increase in blood flow to the tumor or cancer as the tumor or cancer tends to expand and grow outward. Cancer cells or tumor cells may lose their ability to divide in a controlled fashion that can result in the angiogenesis. Tumors can induce blood vessel growth (angiogenesis) by secreting various growth factors, e.g. Vascular Endothelial Growth Factor (VEGF). Such growth factors can induce capillary growth into the tumor, which some researchers suspect supply required nutrients, thereby allowing for tumor expansion. Other clinicians believe that angiogenesis really serves as a waste pathway, taking away the biological end products put out by rapidly dividing cancer cells. In either case, angiogenesis is a necessary and required step for cancer cells to transition and grow from a small harmless cluster of cells to the size of a large tumor. Angiogenesis is also required for the spread of a tumor, or metastasis. The depth of the visualization, imaging, or information providing can be controlled or adjusted as to localize the area being examined. 
     Certain types of cancer can proliferate to different regions, areas, organs, etc. based on metastasis. Metastasis can occur, for example, when single cancer cells break away from an established solid tumor, enter the blood vessel, and be carried to a distant site, where they can implant and begin the growth of a secondary tumor. Evidence now suggests that the blood vessel in a given solid tumor may in fact be mosaic vessels, comprised of endothelial cells and tumor cells. This mosaicity can allow for substantial shedding of tumor cells into the vasculature. The subsequent growth of such metastases will also require a supply of nutrients and oxygen or a waste disposal pathway as provided by subsequent angiogenesis. A tumor thereby typically consists of a population of rapidly dividing and growing cancer cells. Mutations may rapidly accrue within the population of many cancer cells. These mutations of the cancer cells often allow at least some of the cancer cells to develop drug resistance. 
     Tumors including certain cancer cells cannot grow beyond a certain size, while permitting the internal cancer cells deep within the tumor to survive (typically as a result of a lack of oxygen and other essential nutrients that can be provided to the interior cancer cells). Certain tumors or cancers may thereby exhibit necrosis, in which, as the size of the tumor or cancer increases, the original cancer cells that are situated deep within the tumor, and thereby distant from the outer boundary of the tumor or cancer may starve and die as a result of lack of nutrients such as may be provided by the healthy cells. Such starvation or dying may occur since the cell is no longer in contact with healthy cells or supplies of nutrients or oxygen. As such, certain necrotic cancer cells may tend to exhibit different photonic and X-ray characteristics than the living cancer cells, as well as the healthy cells. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can therefore be utilized to detect such necrotic cancer cells. Such depth visualizing, imaging, or information providing of tumors and/or cancer provides only one illustrative embodiment of a use of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     In addition, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information on a temporal/positional reflective basis, and may be performed without positioning the individual in the claustrophobic enclosures, or applying the high-scale electromagnetic radiation associated with, for example, conventional MRI, conventional PET scans, and certain other conventional images. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide different depth visualizing, imaging, or information providing modalities and/or techniques than that of conventional X-ray imaging. For example, conventional X-ray imaging can visualize, image, and/or provide information relating to differences based at least in part on density or atomic number of the matter of the portion of the visualized, imaged, or information provided object, such as differences on density between bone and skin for a person. By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information based at least partially on density of matter such as tissue, as well as providing an additional Compton scattered X-ray visualization, imaging, or information providing modality. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be expected to visualize, image, and/or provide information to a resolution down to approximately 100 microns, or even less as technology improves. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to utilize contrast agents such as, for example, iodine. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to apply a contrast agent at least partially within the confined depth region. Also, certain embodiments of fluorophores (that when accepted by matter may allow the matter to fluoresce under the application of certain X-rays), as well as other electromagnetic responsive material, can be utilized in a similar manner as contrast agent to matter to enhance the Compton scattered X-ray visualization, imaging, or information providing. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be configured to visualize, image, and/or provide information relating to certain fluids and/or fluid locations such as blood (e.g., an element of hemoglobin). Certain blood locations, such as arteries, veins, blood pooling regions, body parts, organs, capillaries, regions, etc., can provide good X-ray contrast based at least partially on iron or other materials in the blood. Therefore, the iron in the blood can cause deflection, absorption, reflection, or Compton scattered X-ray of the X-rays passing there through by some detectable amount. Using conventional techniques, many surgeons, etc. have considerable uncertainty as to the precise location of many blood vessels that they must operate around without contacting or damaging. Such effort by the surgeons, etc. in avoiding the blood vessels is not only dangerous, but also expensive, laborious, and tedious. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can detect blood vessels, as well as other bodily fluid conduits, etc. such as to in many instances allow the surgeons, etc. to operate more safely, quickly, effectively, and efficiently. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured to observe calcium concentration, such as may exist in certain cancers or tumors. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information relating to iodine such as may be present and varying concentrations in portions of the brain, such as may be provided by the thyroid. Certain embodiments may be used in combination with a Compton scattered X-ray visualization, imaging, or information providing agent that can be added to the at least the portion of the individual, either intravascular or otherwise. 
     Certain organs and matter such as tissue that have considerable blood flow either flowing through or contained therein can be visualized, imaged, or have information provided based, at least in part, on the blood situated within the organ or matter. Examples of such organs or matter that can be visualized, imaged, or have information provided as a result of blood can include, but are not limited to: the brain (accounting for approximately 20 percent of the blood flow in the human body at any given time), the heart, the liver, the lung, the appendix, the intestine, as well as certain muscles. The heart therefore is an example of an organ that can be visualized, imaged, or have information provided particularly well based on blood situated relative to the heart. The heart acts to circulate blood throughout the body, and such blood flow through the aorta, the ventricles, and other chambers and regions of the heart can be visualized, imaged, or have information provided (in certain instances in a substantially real-time basis). In addition, the heart additionally includes arteries, veins, and capillaries which can be distinctly visualized, imaged, or have information provided. 
     There are variety of heart aspects and/or conditions that can be image using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . For example, the myocardium could be imaged, as can the heart valves, the coronary arteries, the blood vessels, as well as other matter and/or fluid of or within the heart. Certain blood flows through the valves, the aorta, etc. can be imaged, such as to indicate regurgitation and (that workflow) of blood through a valve; as well as valve stenosis (when blood flows through leaky valves). Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information relating to portions of the myocardium, such as to screen persons for increased risk of myocardial infractions (heart attacks). Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize external and/or Bluetooth image and, such as by utilizing scopes, etc. They can be positioned as desired relative to the heart. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can thereby be extended via scopes or other techniques following blood vessels, lumens, etc. to desired location within the heart. Certain embodiments of the subsurface Compton scattered X-ray visualizer, imager, or information provider  100  can be utilize string open-heart or closed surgery or procedures. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can image at least portions of other organs, such as long as, liver, brain, etc. The lung and liver include internal nodules whose condition can be detected using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider. As such, certain organs and matter can be visualized, imaged, or have image provided by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  based, at least in part, on density or atomic number of the matter. For example, bones, spine portions, cartilage, tendons, ligaments, etc. can be visualized, imaged, or have information provided based on the varying density of the particular organ or matter. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be utilized by orthopedic surgeons, for example, to determine how bones, bone fragments, boney portions, etc. are situated relative to each other. For example, during a spinal construct or bone fracture surgery, the surgeon could determine whether the bone portions are properly aligned or situated as desired; such as to be able to apply a construct, apply a pin, set, etc. Following surgery, the individual (e.g., patient) could be examined using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to determine a variety of orthopedic considerations. For example, are the bones are in the desired location such as aligned, are any pins, fasteners, etc. that have been applied within the individual properly situated or affixed relative to the portions of the individual, etc. Such post-operative examination can be performed with the bone portion(s) exposed, closed up and within the at least the portion of the individual, as well as also contained within a cast or other body part stabilizer. After surgery, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be used to ensure that there has been no retained surgical instruments, sponges, tools, needles, tactile feedback providers, etc. within the at least the portion of the individual. 
     A variety of organs and/or matter can be visualized, imaged, or have information provided based at least partially on density image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques) across the organ. Certain organs can be formed non-uniformly, such as alveoli being formed within lungs, blood vessels, non-uniform heart matter or tissue, etc. Certain organs and matter can include gases, liquids, and/or solids in portions of the organ or matter, such as to make the matter of the organ or tissue non-uniform. 
     As such, whether the Compton scattered X-ray visualization, imaging, or information providing of the organ or matter is based at least partially on the blood or blood component situated therein, the density image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques) across the organ or matter, or the liquid, solid, or gasses contained in at least portions of the organ or matter. It should be understood that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information with considerable definition and at relatively low resolution, while others can be configured with relatively low definition at relatively high resolution. Such definitions, resolutions, and/or other depth visualizing, imaging, or information providing characteristic can be controlled and/or adjusted with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     The operation and structure of the certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can, depending on context, have a considerable number of similarities independent of the type of individual  82 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be operated and/or scaled differently, however, depending upon the condition and/or portion of the individual being visualized, imaged, or having information provided, desired resolution of Compton scattered X-ray visualization, imaging, or information providing, rate of successive Compton scattered X-ray visualization, imaging, or information providing, temporal duration of Compton scattered X-ray visualization, imaging, or information providing, cooperation or consciousness of the individual, and other such factors. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby utilize a variety of X-ray Compton scattered X-ray visualization, imaging, or information providing techniques similar to those that can at least partially include, but are not limited to: conventional X-ray imaging (e.g., transmission and/or fluoroscopy), X-ray Computed Tomography (CT or CAT) scans, Positron Emission Tomography (PET) scans, X-ray imaging at least partially using Compton scattered X-ray, X-ray backscattering imaging, X-ray forward-scattering imaging, and/or other combinations, modifications, and/or developments of X-ray imaging, and/or X-ray based imaging modalities. Compton scattered X-ray visualization, imaging, or information providing technologies could be configured to represent among the more affordable and technically accepted visualization, imaging, or information providing technologies available in medicine. The more affordable a particular visualizing, imaging, or information providing modality is, the more likely it is to be routinely used, and thereupon ultimately developed and accepted. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  therefore can rely on a variety of X-ray technologies. X-ray technologies, in general, can be characterized as particle bombardment, in which the particle includes emitted photons following interaction of the target atom situated at the anode with electrons directed at (or near) the target atom. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  therefore can rely on emission and detection of X-rays, which can take the form of directed or bombarded particles such as photons (and/or Compton scattered photons there from). 
     As such, X-ray visualization, imaging, or information providing technology can be associated and/or operatively combined with certain other imaging modalities such as particle bombardment imaging mechanisms (i.e., the particles including photons), as well as other conventional imaging methodologies as described in this disclosure. Such combination of the Compton scattered X-ray visualizer, imager, or information provider  100  with other imaging modalities are intended to be considered as another embodiment of Compton scattered X-ray visualizer, imager, or information provider, for the purpose of this disclosure, depending on context. As such, the X-rays can be characterized as including photons, which represent a form of electromagnetic radiation, which may be characterized by Maxwell&#39;s Equations. 
     There can be a variety of X-ray visualization, imaging, or information providing modalities can be utilized to provide some level of X-ray Compton backscattered X-ray or forward scattered X-ray visualization, imaging, or information providing (which together can be considered for purpose of this disclosure, depending on context, to be referred to as X-ray Compton scattered X-ray visualization, imaging, or information providing). Certain conventional transmission X-ray imaging modality can rely largely on those X-rays that can be applied to the soft matter or tissue of the at least the portion of the individual  82 , to be transmitted there through (while being absorbed, diffracted, reflected, etc. off bones or other matter). The electromagnetic radiation of the transmitted X-rays can thereupon be received at a distant location of the at least the portion of the individual  82 , after it has passed through the at least the portion of the individual  82 . Such techniques can be used to form the X-ray on the opposite side of the at least the portion of the individual  82 . Visualization, imaging, or information providing, as performed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , can refer to those modalities that relies primarily on the X-ray based electromagnetic radiation that is at least partially reflected, or redirected, as it passes through the soft matter or tissue (or other opaque matter) of the at least the portion of the individual  82 . 
     The term “Compton scattered X-ray visualization, imaging, or information providing”, as described in this disclosure, can be performed by one or more of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Depending on context, certain type of Compton scattered X-ray visualization, imaging, or information providing can include, but is not limited to, visualization, imaging, or information providing, photography, displaying, visualization, imaging, or information generation, computer generation, partial visualization, imaging, or information integration, visualization, imaging, or information capturing, visualization, imaging, or information synthesizing, and other techniques that can at least partially capture depth visualizations, images, and/or provided information which rely, at least in part, on depth visualizations, images, and/or provided information or information obtained from the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     A sufficient amount of the applied X-ray  120  can penetrate into the at least portion of the individual  82  for a penetration depth  170  to accomplish the desired Compton scattered X-ray visualization, imaging, or information providing. By limiting the amount of X-rays, the dosage can be limited as well. A certain amount of the applied X-ray beams  120  will likely be Compton scattered or otherwise deflected throughout the penetration region from the surface  168  (e.g., skin) subsurface down to, and including, the penetration depth  170 . 
     Certain embodiments of the emitter portion  150  can be associated with a variety of embodiments of X-ray based electromagnetic radiation that can operate at a variety of frequencies and/or energy levels, which may therefore visualize, image, and/or provide information down to or at a variety of depths into the at least the portion of the individual  82  within a first of view of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of the emitter portion  150  may be situated within the at least the portion of the individual  82 , adjacent to the at least the portion of the individual  82 , or external to the at least the portion of the individual  82 . Either one, or a plurality of, emitter portion(s)  150  may be provided either within the at least the portion of the individual  82 , adjacent to the at least the portion of the individual  82 , and/or external to the at least the portion of the individual  82 . 
     Certain embodiments of the detector portion  152  can be configured, by comparison, to receive X-ray electromagnetic radiation in the form of scattered X-rays that can be scattered from the applied X-rays provided by the emitter portion of the Compton scattered X-ray visualizer, imager, or information provider  100 , or another device configured to emit applied X-ray. Within this disclosure, certain embodiments of the at least one detector portion  152  can be adjustable such as to receive certain embodiments of the X-ray based electromagnetic radiation such as can be applied to the at least the portion of the individual from the at least one emitter portion  150  (and Compton scattered at least partially within the at least the portion of the individual). Such adjustment of the at least one detector portion  152  can be based on such parameters as direction, signal strength, frequency, energy level, or other such characteristics of the X-ray photons. 
     Certain embodiments of the at least one emitter portion  150 , that is not associated with any particular Compton scattered X-ray visualizer, imager, or information provider  100 , may be utilized that can be detected by one or more distinct detector portions  152  and/or one or more distinct Compton scattered X-ray receiving assembly  151 . For example, certain embodiments of the at least one emitter portion  150  may be configured as a “flooding” embodiment that can provide X-rays within a relatively larger area of the individual, and perhaps a surrounding area. For instance, a remote or local source of the applied X-ray beams  120  can include the emitter portion  150 , and the applied X-ray beams  120  can be at least partially directed at the at least the portion of the individual  82  from a distant emitter portion, or other device, such as could be detected by the detector portion  152 . Certain embodiments of operating rooms, examination rooms, medical offices, research facilities, etc. may be provided with a dispersive embodiment of the at least one emitter portion  150 , such that each user (doctor, medical assistant, technician, dentist, etc.) operationally nearby may utilize their distinct or combined personal or group detector portion  152 , and/or personal or group display or information provider portion  154 . 
     Certain embodiments of the at least one detector portion  152  can be hand-held, and may thereupon be positioned by the user of the Compton scattered X-ray visualizer, imager, or information provider  100 . For instance, if a doctor or dentist would like to examine the subsurface of certain at least the portion of the individual, then certain embodiments of the embodiments of the at least one detector portion  152  could be positioned as proximate the at least the portion of the individual as desired to provide the desired depth visualizing, imaging, or information providing quality and images. Such positionable embodiments of the emitter portion  150 , the detector portion  152 , the Compton scattered X-ray receiving assembly  151 , or other components of the Compton scattered X-ray visualizer, imager, or information provider  100  can be useful to image relatively small portions of the individual in a manner to substantially limit application of X-rays to those regions. For example, in a surgical operating room, medical examination room, veterinarian, etc., certain positionable embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be situated closely adjacent the at least the portion of the individual. 
     The level of applied X-rays can be thereupon be relatively small as compared with flooding-type emitter portions. The user (and/or the visualization, imaging, or information providing controller  97 ) can thereupon control or adjust the depth visualizing, imaging, or information providing. By allowing precise control of the limited at least some matter in the at least a portion of the individual that is being imaged by capturing one or more sequential, adjustable, controllable, or continuous visualizations, images, or provided information, less X-ray electromagnetic radiation may be applied to the individual, the user, and/or others in the vicinity. Certain embodiments of the detector portion could be mechanically mounted, or motion-stabilized (such as is understood in computer graphic systems), such as to limit relative motion of the visualize, image, and/or provide information on the display portion. 
     Certain embodiments of the at least one display portion  154 , as described in this disclosure, can display at least one visualize, image, and/or provide information based at least partially on the Compton scattered X-ray based electromagnetic radiation that has been received by the at least one detector portion  152 . Certain embodiments of the at least one display portion  154  can be adjusted such that the user can observe what they desire, adjust the visualization, image, or provided information, and/or otherwise control a variety of operations of the Compton scattered X-ray visualizer, imager, or information providers  100 . 
     Certain embodiments of the at least one display portion  154  can display at least portion of the visualize, image, and/or provide information relating to the portion of the individual  82  to the individual, such as a patient either alone or in combination with a physician, etc. The fact that certain embodiments of the Compton scattered X-ray visualizer, imager, or information providers  100  can operate on a substantially real-time basis can make the individual more aware of their condition based on an accurate Compton scattered X-ray visualization, imaging, or information providing of at least a portion of their body. Consider certain individuals who may have an injury, illness, sickness, medical condition, etc. who can have an visualize, image, and/or provide information relating to an appropriate location likely be provided with a near-temporal/positional reflective visualize, image, and/or provide information relating to an appropriate location. As such, they can have more knowledge of their treatment or condition, understand their treatment, and/or perhaps even participate in their treatment. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to control a treating mechanism that can be used to treat the at least the portion of the individual  82  at least partially in response to the X-ray Compton scattered X-ray information. 
     In certain injuries or conditions such as ligament tears, joint or bone injuries/fractures, organ conditions, etc., certain embodiments of the Compton scattered X-ray visualizer, imager, or information providers  100  could visualize, image, and/or provide information in a substantially continuous manner as the at least the portion of the individual undergoes motion of an affected joint or location. For example, an orthopedic surgeon could consider or examine a knee joint or bone of a patient during flexure, relaxation, or other motion of that body part. In certain instances, dye, contrast agents, or other Compton scattered X-ray visualization, imaging, or information providing-enhancing materials could be applied to at least the portion of the individual such as to improve the Compton scattered X-ray visualization, imaging, or information providing of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information providers  100  can interface and/or interact with each other to provide Compton scattered X-ray visualization, imaging, or information providing operation(s) between a number of the at least portions of the Compton scattered X-ray visualizer, imager, or information providers. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  (or portions thereof) can include the one or more emitter portion  150 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include the one or more detector portion  152 , or alternately one or more Compton scattered X-ray receiving assembly  151 . Still yet other embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include one or more display portions  154 . Various of the emitter portions  150 , detector portions  152 , and/or display portions  154  can be combined as desired, and utilized in an appropriate configuration for the desired Compton scattered X-ray visualization, imaging, or information providing application, only certain illustrative embodiments of which are described in this disclosure. 
     Within this disclosure, certain embodiments of the at least one emitter portion  150  can be configured to apply X-ray based electromagnetic radiation at least partially toward the at least the portion of the individual  82 . The frequency, energy level, or other operational characteristics and/or structural characteristics of the X-ray based electromagnetic radiation may differ considerably (and be less objectionable or dangerous) than as applied to patients by conventional X-ray (fluoroscopy) techniques. This is largely a result of lower X-ray dosages being applied to the individual since the X-rays can rebound or scatter from the at least the portion of the individual  82  after it has passed through only a relatively short distance within the at least the portion of the individual. As such, electromagnetic shielding that is applied to patients undergoing fluoroscopy can be limited, or at least considerably reduced, by using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain airport screening systems, for example, use X-ray scatter visualization, imaging, or information providing from security screening without undue concern of excessive radiation being applied to the travelers of users of the X-ray scanning systems. 
     Applied X-rays of limited strength could be useful in depth visualizing, imaging, or information providing sensitive at least portions of individuals such as embryos, fetuses, etc. within pregnant women. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could image in a manner such that the X-rays stop just short of sensitive matter or tissue, organ, or other matter (e.g., the uterus, heart, brain, etc.) and thereby limit exposure of ionizing radiation to the embryos, fetuses, etc. for example. In actuality, almost any matter within the individual can be considered as sensitive to some degree, particularly relative to desirability of limiting exposure of X-rays there to. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are particularly suited to correcting or applying applied X-rays and/or scattered X-ray to controllably limited regions within the individual. Additionally, there may be a considerable number and variety of organs, portions, or segments of the body that would do better with limited applied X-rays. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can limit transmission of X-rays during depth imaging to certain of such matter, organs, portions, or segments of the body. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured to visualize, image, and/or provide information relating to areas as desired within the particular individual, and limit exposure of X-ray radiation to other (perhaps sensitive) regions. 
     Within this disclosure, the Compton scattered X-ray detected by certain embodiments of the detector portion  152  can be back Compton scattered, forward Compton scattered, deflected, or other distortions of the path of the X-ray based electromagnetic radiation that fall within the scope of the present disclosure, while remaining within the intended scope of Compton scattered X-ray. Certain embodiments of the detector portion  152  can be associated with a variety of embodiments of X-ray based electromagnetic radiation, which can operate at a variety of frequencies and/or energy levels, and may therefore visualize, image, and/or provide information down to or at a variety of depths into the at least the portion of the individual  82 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, can be configured with one or more of the emitter portion  150 , the at least one Compton scattered X-ray receiving assembly  151 , the detector portion  152 , and/or the display portion  154 , or any combination thereof. With those embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  having no emitter portion  150 , the X-ray based electromagnetic radiation can be at least partially provided by another device. For instance, a number of the display portion(s)  154  (or alternately at least one display portion that can be viewed by numerous persons), can be utilized by or controlled by a number of persons such as surgeons, technicians, assistants, etc. that can be applied by a single strategically located emitter portion  150 . The emitter portion  150  may, or may not, be included as a portion of at least one of the Compton scattered X-ray visualizer, imager, or information provider(s)  100 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be controlled, such as to allow its operator to select different penetration depths  170  (or range of penetration depths) to which the Compton scattered X-ray visualizer, imager, or information provider can visualize, image, or provide information. Within certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the penetration depth  170  for visualizing, imaging, and/or information providing may vary as a function of the energy applied to or contained within the applied X-ray, and/or the frequency, energy level, or other characteristics of the X-ray photons of the applied X-ray  120 . The matter (e.g., skin, tissue, bone, etc) to which the applied X-ray  120  is being applied will also affect the visualizing, imaging, or information providing characteristics. As certain characteristics of the applied X-ray are increased, it may likely effect the maximum penetration depth  170  (see  FIGS. 18  and/or  20 ) to which the applied X-ray Compton scattered X-ray radiation will likely travel to prior to Compton scattered X-ray, or thereby visualize, image, and/or provide information down to. While a limited number of X-rays might travel within the at least the portion of the individual to a depth greater than the penetration depth  170 , certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to limit the effects of those few X-rays relative to the visualization, imaging, or information providing. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide for image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques) as described with respect to  FIG. 16 . Within this disclosure, such image combining techniques as relating to Compton scattered X-ray visualization, imaging, or information providing techniques can, depending on context, refer to Compton scattered X-ray visualization, imaging, or information providing between two of the at least one prescribed visualization, imaging, or information providing depths  170   a  and  170   b . Each prescribed visualization, imaging, or information providing depth  170   a  and  170   b  can be situated at least some distance from the skin or surface  168  of the individual (such as illustrated in  FIGS. 16  and/or  17 ). Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can obtain multiple sampled visualize, image, and/or provide information relating to data pertaining to X-ray Compton scattered X-ray Compton scattered X-ray visualization, imaging, or information providing at different depths either sequentially or in parallel. As such, the multiple sampled visualize, image, and/or provide information relating to data can be considered as Compton scattered X-ray visualization, imaging, or information providing a similar sample space down to different penetration depths  170   a  and  170   b.    
     Certain ones of the multiple sampled visualize, image, and/or provide information relating to data can thereupon be compared at least partially by image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques). As such, those details, images, information, visualizations, etc. that are situated in the shallower penetration depth  170   a , and not in the deeper penetration depth  170   b , as described with respect to  FIG. 16 , can be digitally subtracted out, transformed out, or otherwise computed out. By digitally differentiating the matter, tissue, objects, etc. being visualized, imaged, or have information provided at the shallower penetration depth  170   a  from the deeper penetration depth  170   b , the depth visualizations, images, and/or provided information or other information relating to matter between the shallower and deeper penetration depths can be obtained. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to obtain a X-ray Compton scattered X-ray information at least partially using X-ray Compton scattered X-ray to derive visualize, image, and/or provide information through at least one matter (e.g., tissue or other matter) of the at least the portion of the individual  82 . Such visualizing, imaging, or providing information can be provided at least at both a first depth region and at a second depth region, both associated with the at least a common portion of the individual  82 . The depth difference between the first depth regions that extends to a first penetration depth  170   a  and the second depth region that extends to a second penetration depth  170   b  can be used for subtraction or combination Compton scattered X-ray visualization, imaging, or information providing techniques, as described in this disclosure. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that utilize subtraction or combination Compton scattered X-ray visualization, imaging, or information providing techniques can therefore act to visualize, image, and/or provide information at different penetration depths  170   a  and  170   b . As such, adjustment of the subtraction or combination Compton scattered X-ray visualization, imaging, or information providing technique can be performed at least partially by, for example, controlling and/or adjusting the frequency of energy level of the X-ray photons at two levels to provide two X-rays. Each of the controlling and/or adjusting the frequency of energy level of the X-ray photons can be detected distinctly to the at least one prescribed visualization, imaging, or information providing depths  170   a  and  170   b . Thereupon, the difference of the shallower level image undergoes image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, image subtraction, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques) from that of the deeper image. The image subtraction or combination depth visualizing, imaging, or information providing techniques can thereby be used to provide information about matter within range of volumes between two penetration depths  170   a  and  170   b  in  FIGS. 16 and 17  from the surface  168 , etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information at a first controllable one of the at least one visualization, imaging, or information providing depth range to the at least one first prescribed visualization, imaging, or information providing depth to obtain the first Compton scattered X-ray image information. Certain of these embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information at a second controllable one of the at least one visualization, imaging, or information providing depth range to the at least one second prescribed visualization, imaging, or information providing depth to obtain the second Compton scattered X-ray information. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to computationally differentiating the data associated with the first X-ray Compton scattered X-ray information and the second X-ray Compton scattered X-ray information. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can also utilize a time of flight measurement to visualize, image, and/or provide information at the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth, as described with respect to  FIG. 17 . Such time of flight measurement can utilize precise pulse signals which can be characterized as at least one input pulse signal and at least one return pulse signal (allowing fractional-second temporal Compton scattered X-ray visualization, imaging, or information providing resolution so as to achieve suitable Compton scattered X-ray visualization, imaging, or information providing resolution). The briefer the duration of the emitted pulse signal and the detected pulse signal, the lesser the achievable resolution (lesser resolution leading to improved Compton scattered X-ray visualization, imaging, or information providing characteristics). Using time of flight techniques, the emitted pulse signals can be applied by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to the surface  168  of the at least the portion of the individual  82 . Providing the time of flight of the return signal can be measured with sufficient accurately (e.g., resolution in picoseconds for certain embodiments, such as those that utilize streak cameras, pixellated streak cameras, avalanche detectors, CCDs, etc.) then the time of the detected pulse signal can be gated to provide sufficient accuracy, and the time of flight can be determined, from which the distance or depth can be determined. 
     By using the time of flight embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the emitter portion  150  can transmit the at least one input pulse and the detector portion  152  can detect the return time of the at least one return pulse signal. As described with respect to  FIG. 17 , a time of flight calculation  160  can be determined based on the amount of time required for the at least one input pulse signal to be applied to the at least the portion of the individual; which can thereupon each be Compton scattered into one or more return pulse signal. The Compton scattered return pulse signal(s) will be modified based at least in part on the characteristics of the matter of the individual through which the pulse signals pass (e.g., pulse applied X-ray and/or pulse scattered X-ray). 
     One use of combination of Compton scattered X-ray visualization, imaging, or information providing (including subtracting, and other such processes) may involve Compton scattered X-ray visualization, imaging, or information providing matter, an organ, etc. that is located within a region that is situated a considerable depth from the surface  168 . During depth visualizing, imaging, or information providing of such a deep organ, matter, etc., additional matter, organs, etc. that are positioned between the depth visualizing, imaging, or information providing component(s) of the Compton scattered X-ray visualizer, imager, or information provider  100  and the imaged region may not be necessarily be displayed. Therefore, additional matter, organs, tissue, etc. may not be visualized, imaged, or have information provided using image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques). 
     As such, certain organs, matter, etc. that are situated deep within the at least the portion of the individual may be imaged without depth visualizing, imaging, or information providing interference from shallower matter using subtraction or combination of Compton scattered X-ray visualization, imaging, or information providing techniques, such as with image combination (e.g., image subtraction, time of flight, image transformation, deconvolution, weighted subtraction, functional subtraction, and group including inverse integral transform, subtractive inverse integral transform, inverse functional transform, and subtractive inverse functional transform, or other such image processing techniques). Alternately, certain matter, tissue, organs, etc. can be imaged by positioning the at least one emitter portion  150 , the at least one detector portion  152 , and/or the at least one Compton scattered X-ray receiving assembly internally at a suitable position relative to the imaged organs, matter, etc. One skilled with the various embodiments, configurations, and uses of the Compton scattered X-ray visualizer, imager, or information provider  100  could determine which depth visualizing, imaging, or information providing technique would provide the better quality depth visualizations, images, and/or provided information or images, less invasively, thereby lowering the X-ray dosages to the user and/or individual. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can at least partially rely on Compton scattered X-ray visualization, imaging, or information providing matter within the at least the portion of the individual  82 , such as muscle, skin, blood vessels, fluids (e.g., blood, lymph), etc. Within this disclosure, the soft Compton scattered X-ray visualization, imaging, or information providing may be compared to hard imaging such as occurs in conventional backscatter imaging that may occur when the imaging modality encounters a hard or reflective surface such as bones, metals, etc. By providing Compton scattered X-ray-based Compton scattered X-ray visualization, imaging, or information providing of soft matter, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow detection of variations of certain characteristics of the soft matter, such as may be the case of calcification of the skin such as occurs relative to a matter aberration. Such matter aberrations as certain breast cancers can be identified due to the calcification of the tumor or cancer. By allowing Compton scattered X-ray-based Compton scattered X-ray visualization, imaging, or information providing of at least some soft matter, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide for locating. Such locating or positioning based at least partially on matter aberration can be applied to such varied applications as positioning organs, circulatory portions (e.g., veins, arteries, etc), blood flows, nerves, bones, etc. relative to the at least some matter of the at least the portion of the individual  82 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to limit certain contact or damage of arteries, veins, capillaries, or other blood (or other fluid) vessels, etc. Consider the difficulty during surgery, etc., of avoiding such contact that may be at some uncertain location within the individual. Considering the number of blood or other fluid vessels within the body, as well as the likelihood of damage using scopes, tools within incisions, cutting tools, tactile feedback providers, other tools, etc., the scope of the difficulty during surgery, etc. becomes evident. In certain instances, a surgeon may even be unaware if they have damaged a hidden blood vessel or other fluid capillary. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be positioned to visualize, image, and/or provide information the region in which the physician or veterinarian is working. Alternately, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be connected to, or otherwise associated with, tools being applied to the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can also allow surgeons, and/or their tools, to avoid or limit contact with particular nerves, organs, matter, etc. Such depth visualizing, imaging, or information providing which allows users such as surgeons, dentists, veterinarians are likely to come in proximity with blood vessels, fluid vessels, nerves, organs, matter, etc. to limit contact their with. Such imaging or visualization to limit contact with certain portions of the body can be performed on a substantially real-time basis, or another basis as desired, and would be expected to considerably reduce the duration of operations, procedures, etc, by such users as doctors, dentists, veterinarians, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can also be configured to locate, analyze, and/or treat blood pooling or other fluid pooling. With certain injuries from bombs, explosives, injuries, vehicular and other crashes, certain illnesses, etc., it can be difficult with conventional imagers to locate blood pooling within portions of humans, animals, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could determine, for example, a trajectory of a bullet, explosive, bomb, etc. such as could be located by determining the location (such as in a trail or pool) of blood through organs, matter, etc. Other naturally occurring blood or fluid pools could be located, examined, and/or treated. 
     Another example of a bodily fluid which might be located using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  is lymph fluid. Following certain cancers, for example, certain lymph nodes may have to be removed. Lymph nodes function to largely remove lymph fluid from the body. With lymph nodes removed, there can be a considerable collection of the lymph fluid in the body, which can add to weight gain to the individual and/or eventually become infected. Other types of bodily fluids may be visualized, imaged, or have information provided. 
     Certain embodiments of the at least one detector portion  152 , as described at various locations through this disclosure, can be controlled and/or adjusted to receive photons at least partially emitted from the at least one emitter portion  150 . Such control and/or adjustment can be performed in a manner that can be used to provide Compton scattered X-ray visualization, imaging, or information providing using certain embodiments of the at least one display portion  154 . 
     Certain embodiments of the depth visualization, imaging, or information providing controller  97  can thereby include, but is not limited to, at least one control and/or adjustment portion  934 . Certain embodiments of the detector portion  152  of the Compton scattered X-ray receiving assembly  151  can be configured to measure the amount of X-ray based electromagnetic radiation (e.g., scattered X-rays in the form of photons) that is received by the at least one detector portion  152 . Certain embodiments of the control and/or adjustment portion  934  can be configured to control and/or adjust the position, angle, or other operating parameter of at least a portion of the at least one Compton scattered X-ray receiving assembly  151 . Certain embodiments of the control and/or adjustment portion  934  can be used to enhance, modify, filter, or otherwise effect reception of the X-ray based electromagnetic radiation (e.g., in the form of photons), such as may be emitted from the at least one emitter portion  150 . Certain detector portions  152  of certain embodiments of the Compton scattered X-ray receiving assembly  151  can be omni-directional, multi-directional, or at least have a suitable directional range as to suitable detect the X-ray based electromagnetic radiation being emitted towards the at least the portion of the individual. Certain embodiments of the control and/or adjustment portion  934  can be configured to the relative angle(s), frequencies, and/or positions of the at least one emitter portion  150 , and/or the at least the portion of the individual  82 . Certain embodiments of the control and/or adjustment portion  934  can be configured to ensure suitable transmission or reception of X-ray based electromagnetic radiation to allow proper depth visualizing, imaging, or information providing. 
     Certain embodiments of the at least one Compton scattered X-ray receiving assembly  151  can also include a detector portion transfer portion, not shown, in which the detected photons, Compton scattered X-ray visualization, imaging, or information providing information, data, etc. relating to the X-rays that can be at least partially Compton scattered at/within the at least the portion of the individual. Certain data, information, images, visualizations, etc. as obtained at least partially be the Compton scattered X-ray receiving assembly  151  can be displayed by the at least one display portion  154 , perhaps in a form of the at least one visualization, image, or provided information. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information at a substantially real-time basis, while other embodiments can be configured to visualize, image, and/or provide information at a slower repetitive rate. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can even be configured to visualize, image, and/or provide information relating to one or more non-repetitive depth visualizations, images, and/or provided information. Such selection of Compton scattered X-ray visualization, imaging, or information providing on substantially temporal/positional reflective can allow such users as a surgeon, doctor, veterinarian, dentist, etc. to obtain conditional information, location information, etc. at desired subsurface locations of the at least the portion of the individual  82  as quickly as desired. Within this disclosure, the term “subsurface”, can, depending on context, refer to depth visualizing, imaging, or information providing matter underneath, or across, the surface  168  of the at least the portion of the individual  82  (possibly depth visualizing, imaging, or information providing the surface of the individual). Certain of the surfaces  168  can include skin, internal surfaces, etc. that can be in communication with outside via an opening such as one which a scope that could be applied, such as mucous membranes, at least partially endothelium, internal membranes or skin(s) at least partially defining or surrounding a lumen, via blood vessels, etc. Certain embodiments of at least portion of the Compton scattered X-ray visualizer, imager, or information provider  100  (such as the emitter portion  150  or the Compton scattered X-ray receiving assembly  151 ) could be applied to within the at least the portion of the individual  82  using such technologies as a scope, a needle, an injected or implanted device. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be configured to, for example, image a moving organ as described with respect to  FIG. 31 . Such visualization, imaging, or providing information relative to moving organs can be applied to, for example, at least a portion of the heart, kidney, brain, stomach, intestine, or other organ that can be defined based on visualization, imaging, or information providing, or variations such as by edges of the particular organs being visualized, imaged, or information provided. 
     Consider that a moving two dimensional or three dimensional image of a portion of the heart could be provided using certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Such depth visualizing, imaging, or information providing could be useful for diagnosis purposes, during surgery, during screening of susceptible individuals, etc. Depth visualizing, imaging, or information providing could be performed on a heart valve, as well as the associated depth visualizing, imaging, or information providing through that heart valve. Heart-based depth visualizing, imaging, or information providing could be provided by positioning the at least one emitter portion  150  and the at least one detector portion  152  in suitable proximity to (or within) the heart utilizing suitable scopes, implants, etc. along with wireless and/or wired-based technology. The configuration, position, motion, reflex of the heart, aorta, arteries, valves, etc. can be used with suitable resolution and refresh rates using certain Compton scattered X-ray visualizer, imager, or information provider  100  configurations. 
     Certain embodiment the Compton scattered X-ray visualizer, imager, or information provider  100  could be applied to image matter or tissue contained within such internal lumens to the human body (and/or image from the internal lumens). Such internal lumens can include, but are not limited to, those at least partially defining: the respiratory tract, the cardiovascular system (e.g., heart, blood vessels), at least a portion of a CSF-space of the nervous system (e.g., the spinal canal, the ventricles of the brain, the sub-arachnoids space, etc.), at least a portion of the urinary tract (for example a urethra), at least a portion of the lymphatic system, at least a portion of the abdominal cavity, at least a portion of the thoracic cavity, at least a portion of the gastrointestinal tract, at least a portion of a reproductive tract (either the female reproductive tract—e.g., a lumen of a fallopian tube), or the male reproductive tract (including various lumens including but not limited to the epidermis, vas deferens or ductile deferens, efferent duct, ampoule, seminal duct, ejaculatory duct, or urethra), the biliary tract, a nostril or nasal cavity, the oral cavity, the digestive tract, the tear ducts, a glandular system, and/or the reproductive tract. Other body lumens may be found in the auditory or visual system, or in interconnections thereof, e.g., the Eustachian tubes. As such, three can be a considerable variety of applications for certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information at a single resolution device, such as may be appropriate for a particular Compton scattered X-ray visualization, imaging, or information providing application, a particular resolution, or a particular use. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to visualize, image, and/or provide information at a variety of resolutions or applications, such as can be controlled by certain embodiments of the visualization, imaging, or information providing controller  97  as described in this disclosure with respect to  FIG. 1 . Such variation of the Compton scattered X-ray visualization, imaging, or information providing resolution may vary depending on use. For instance, in those instances where the embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  is being used to determine a location or position of an organ, bone, etc., relatively high resolution (e.g., low quality) Compton scattered X-ray visualization, imaging, or information providing can be utilized. By comparison, in those instances where the embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are being used to detect tumors or the like, a relatively improved resolution (high quality) visualize, image, and/or provide information may be obtained and utilized. 
     Certain embodiments of the X-ray Compton scattered X-ray visualization, imaging, or information providing can thereby utilize one or more emitter portions  150  that can apply X-ray radiation which can be Compton scattered and/or reflected off at least the portion of the individual  82 . As such, certain conventional X-ray Compton scattered X-ray visualization, imaging, or information providing may be referred to as “soft X-ray visualization, imaging, or information providing” since it is reflective (relying at least partially on reflection/refraction of X-ray based electromagnetic radiation—photons), instead of being at least partially transmissive as with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain transmissive types of conventional X-ray visualization, imaging, or information providing can also utilize fluoroscopy. In addition, X-ray Compton scattered X-ray visualization, imaging, or information providing may often utilize less powerful X-ray signals then conventional X-ray imaging since the photons of the former do not have to pass through the at least the portion of the individual  82 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  therefore provide a mechanism to examine or view an aberration in the surface  168  that can be provided in temporal/positional reflective, real time or near real time, or in a controllable repeatable or non-repeatable fashion. Certain embodiments of the Compton scattered X-ray visualization, imaging, or information providing time (duration) can be controlled or adjusted based, at least in part, on such factors as: input from the user, Compton scattered X-ray visualization, imaging, or information providing detail. Other operational characteristics of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be adjusted and/or controlled by certain embodiments of the visualization, imaging, or information providing controller  97 , as described in this disclosure. 
     It is to be understood that the included description(s) of the at least one emitter portion  150 , the at least one detector portion  152 , and/or the at least one display portion  154 , as described in this disclosure, are intended to be illustrative in nature but not limiting in scope. Modifications and/or alterations of the devices  150 ,  151 ,  152 , and/or  154  from those described in this disclosure are within the intended scope of the present disclosure, depending they still are within the scope of the claims. 
     As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured such that the physician, dentist, etc. using them can observe a subsurface visualization, image, and/or provide information of the region of the at least the portion of the individual  82 . Certain particulars of the Compton scattered X-ray visualization, imaging, or information providing and/or the region can vary depending on the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 . For example, certain Compton scattered X-ray visualization, imaging, or information providing can correspond to where they are looking, wherein they desire to look, or alternatively where they direct the Compton scattered X-ray visualizer, imager, or information provider  100  to visualize, image, or provide information. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can present visualizations, images, and/or provide information to a group of persons particularly associated with the Compton scattered X-ray visualizer, imager, or information provider. 
     With conventional X-rays that are transmitted through the at least the portion of the individual  82 , including fluoroscopy as well as conventional transmissive X-rays techniques, X-rays may be configured to be applied such that the electromagnetic radiation is applied with sufficient energy level and/or frequency of the X-ray photons to be applied through the portion of the at least some matter. The X-ray photons resulting from Compton scattered X-ray is traditionally not utilized in conventional fluoroscopy-based imaging modalities. As such, with certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the applied X-ray beams  120  do not have to be applied exclusively, but can represent a percentage (even a minority) of the electromagnetic radiation being applied to the at least the portion of the individual  82 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize Compton scattered X-rays that do not have to backscatter or backwardly reflect from within the at least the portion of the individual  82 . Instead, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can pass at least partially through the at least the portion of the individual  82  and be somewhat deflected or forward scattered, such that as described within the at least the portion of the individual  82 . The X-ray based electromagnetic radiation that is detected as “Compton scattered” information may thereby at least partially backscatter, forward scatter, reflect from, or be at least partially deflected by, the at least the portion of the individual  82 . Certain embodiments of the applied X-ray from the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied can be applied at various angles (ranging from perpendicular to substantially parallel to the contacting surface  168  of the at least the portion of the individual  82 ) relative to the surface of the matter of the at least the portion of the individual  82 . 
     The visualization, imaging, or information can be presented to the user such as a surgeon, veterinarian, dentist, researcher, etc. by a variety of display portion means that can include, but are not limited to: an external monitor, a head-mounted display, stereoscopic projection, a scope device (i.e., endoscope, etc.). Certain portions of different embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used in combination, such as a scope-based emitter portion  150  which can be used in combination with an at least partially external-based or internal-based detector portion  152  from another embodiment of the Compton scattered X-ray visualizer, imager, or information provider. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be usable or are adjustable to visualize, image, and/or provide information to various controllable and/or adjustable depths. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be configured to visualize, image, and/or provide information to a depth of a few millimeters. Other embodiments could be configured to visualize, image, and/or provide information to a depth through the at least the portion of the individual  82 , if provided with X-ray electromagnetic radiation having sufficient energy or of a suitable X-ray photon frequency or energy level. The depth of Compton scattered X-ray visualization, imaging, or information providing of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be a function of frequency, energy level, or other characteristic of the X-ray photons used to generate the Compton scattered visualization, image, type of matter of the individual, as well as power applied to generate the Compton scattered X-ray visualization, image, or provided information. 
     For example, a user or operator can utilize certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to visualize, image, and/or provide information at a variety of depths. It is envisioned that a variety of depth visualizing, imaging, or information providing modalities can be utilized for the different embodiments of the debt-controllable Compton scattered X-ray visualizer, imager, or information provider  100 . With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, the Compton scattered X-ray visualization, imaging, or information providing can visualize, image, and/or provide information from the surface  168  down to and including the controlled depth of the at least the portion of the individual  82 . 
     Certain embodiments of a robotic or automated system can utilize certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , such as to allow a wide variety of automated or robotic devices to operate at least partially in response to visualization, imaging, or provided information. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider could scan the at least the portion of the individual for suspicious areas such as melanomas automatically, and indicate any suspicious region to a doctor or operator to be more closely considered. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to control a robotic device at least partially in response to the X-ray Compton scattered X-ray information. It may be envisioned that certain automated devices or robotic devices could be configured to allow surgery, internal procedures (e.g., scope-based or other), and/or other internal operations based at least in part on visualization, imaging, or information providing information obtained at least in part from the Compton scattered X-ray visualizer, imager, or information provider  100 . Such automated or robotic procedures hold out the promise of considerable precision, as well as a variety of automated or remotely-controlled operation. 
     A variety of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to allow control and/or adjustment of the within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth of the Compton scattered X-ray visualization, imaging, or information providing. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow an operator such as a surgeon, support person, other person, machine, robot, etc. to provide input, or manually, to control and/or adjust the depth at which the at least one depth-adjustable embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 . With certain depth-adjustable embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , at least one of the selected depth that is being visualized, imaged, or have information provided can be targeted (for example, by tuning the X-ray beam intensity, energy level, frequency, or other characteristics) either manually and/or automatically. 
     One such technique that can be used to adjust and/or control the within the at least one visualization, imaging, or information providing depth range to the at least one prescribed visualization, imaging, or information providing depth at least partially by angling the applied X-rays relative to the surface  168  of the at least the portion of the individual. Provided the Compton scattered X-ray visualizer, imager, or information provider  100  is configured to pass through a prescribe depth of matter, the greater the angle at which the applied X-rays contact the surface  168 , the lesser the travel distance of the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth into the matter. 
     Another such technique that can be used to adjust and/or control the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can involve providing a depth equivalent material or device between that the applied X-rays should pass through. For example, assume that the depth equivalent material or device represents the equivalent of 2 mm. Assuming the Compton scattered X-ray visualizer, imager, or information provider  100  is configured to image at 5 mm, the image subtraction or combination effect of the depth equivalent material would result in Compton scattered X-ray visualization, imaging, or information providing down to a depth of 3 mm. A number of depth equivalent material of devices can be provided such as to allow control and/or adjustment over the desired substantially scattered depth range to the at least one prescribed substantially scattered depth. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured to obtain the X-ray Compton scattered X-ray information in a manner capable of temporally reflecting motion (conscious or reflexive) of portion(s) of the individual  82  than are deeper than those described up to this point. For example, certain embodiments of the aberrative matter, etc. may be configured to visualize, image, and/or provide information at least one organ(s), bone(s), bone portion(s), blood vessel(s), blood capillar(ies), etc. that may be spaced relatively deeply subsurface. By altering certain operational characteristics of the X-ray based electromagnetic radiation that may be applied by the at least one emitter portion(s)  150  as described with respect to  FIG. 1 , as well as received by certain embodiments of the at least one detector portion(s)  152 , the visualization, imaging, or information providing depth can thereby be controlled. 
     Considering that conventional X-rays can image by X-rays passing completely through the at least the portion of the individual, it should be understood that Compton scattered X-ray technologies can be used to visualize, image, and/or provide information a considerable depth into the at least the portion of the individual provided the X-rays are configured to travel with a suitable frequency of the X-ray photons at a suitable energy level, etc. Such Compton scattered X-ray visualization, imaging, or information providing of at least partially internal organs, bones, etc. can better be performed in some internal location that is not at least partially hidden, distorted, or obscured by bones, metal or other X-ray diffusive matter. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured such that the obtaining the X-ray Compton scattered X-ray information such as can be obtained visually. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can visualize, image, and/or provide information from a variety of perspectives. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide different types of views. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to provide depth visualizations, images, and/or provided information and/or visualize, image, and/or provide information in substantially temporal and/or positional reflective condition, such as could be detected by the user. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could provide depth visualizations, images, and/or provided information and/or visualize, image, and/or provide information at absolute locations in space. For instance, a particular bone, joint, portion of an organ, etc. could be located or situated at a precise position with respect to the at least the portion of the individual  82 , a device, a location in space, a building or room, etc. Such determination of a position, situation, or location could be determined using a global positioning system (GPS), another global positional program or device, or using a coordinate system or device relative to the at least the portion of the individual, or the location thereof. In addition to the location or position, there may be an indication of the condition of the particular bone, joint, portion of the organ, etc. at that location. Once such positional information is obtained, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could utilize, implant, generate at least portions of the depth visualizations, images, and/or provided information such as may be provided using an additional or alternate visualization, imaging, or information providing modality, an other application, other maps, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that are so configured to provide good resolution should be capable of providing 100 micron, or better, resolution based on the X-ray Compton scattered X-ray technology. As described in this disclosure, streak camera, pixellated streak cameras, CCDs, avalanche detectors, and other detector-type devices can be used to provide very good resolution and accuracy. With such resolution, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider could be used to determine positional information precisely and accurately. Such combining of multiple imaging and/or visualizing modalities may limit the depth visualizing, imaging, or information providing computation necessary by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  by, for example, inputting image information already derived from other sources. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby provide for overlaying of combining of the X-ray Compton scattered X-ray visualization, imaging, or information providing with other conventional and/or imaging modalities. For example, MRI could be overlaid on certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . MRI provides a good example of an additional imaging modality that can be used in combination with X-rays, since MRI is generally understood to be highly accurate, provide considerable visualizations, images, and/or provided information in the medical area, and can be quite expensive. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can capture or otherwise obtain temporal/positional reflective Compton scattered X-ray visualization, imaging, or information providing, and a variety of locative techniques in utilized to match recently obtained MRI or other imaging modality images (two or three dimensions) in the imaged region. For example, certain fiducials could provide position information for MRI (or other imaging modality) such as could also provide position information for certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     As such, the location of the fiducials they can provide position information for MRI could be used to co-locate the MRI and/or the subsurface Compton scattered X-ray. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , once the X-ray subsurface Compton scattered X-ray depth visualizations, images, or provided information has been located with respect to the other imaging modality such as MRI, the depth visualizations, images, and/or provided information, depth visualizations, images, or provided information relating to MRI can be imported, utilized, and/or displayed by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain of the fiducial can be endogenous (such as blood within the blood vessel); while other fiducials can be exogenous (such as a bead which is implanted under the skin. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can allow providing inputting higher energy, such as may result in demarcated finer structures within the visualized, imaged, or information provided regions that are located deeper into the at least the portion of the individual. This control or adjustment of the visualization, imaging, or information providing can result since a larger percentage of the X-ray based electromagnetic radiation (e.g., photons) have the ability to be applied by the emitter portion  150  to travel within the at least the portion of the individual to the deeper regions, scatter, and travel out again to be detected. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide some amount of adjustment, control, and/or shift to the X-ray based electromagnetic radiation, which with certain embodiments can be varied, adjusted, or controlled, especially when Compton scattered X-ray visualization, imaging, or information providing deeper matter, bones, or organs, etc. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are therefore useful in providing relatively detailed visualizations, images, and/or provided information about one or more of: matter, aberrative matter embedded in tissues, bones, organs, etc. A considerable number of conventional imaging modalities may be useful for Compton scattered X-ray visualization, imaging, or information providing at least some of the matter within the body of the individual with such resolution. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide some quantification, automated observation, and/or feedback associated with the Compton scattered X-ray in a temporal/positional reflective basis, and in certain instances at a variety of controllable depth(s). In certain instances, the Compton scattered X-ray visualization, imaging, or information providing can be performed through modifiable (in-vivo) matter with low latency. Illuminating electromagnetic characteristics selected with characteristics having intensity and wavelengths selected to limit transmission of excessive electromagnetic radiation (e.g., X-ray) into the body of the individual, and thereby limit X-ray dosages. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to scan across the surface  168  (or through a region) of the at least the portion of the individual  82 . By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to capture at least one visualization, at least one image, and/or provide information substantially at the same time. The particular characteristics of the Compton scattered X-ray visualizer, imager, or information provider  100  imaging modality are intended to be illustrative in nature, but not limiting in scope. 
     At least portions of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can include scopes such as endoscopes as described with respect to  FIG. 23 . Within this disclosure, the term “endoscope” can, depending on context, refer to an one of a variety of scopes that can be applied at least partially internally or externally, such as to one or more of the tracts that are at least partially open that can include, but are not limited to: the gastrointestinal tract, the respiratory tract, the urinary tract, the female reproductive system, etc. Such visualization, imaging, or information providing relative to the tracts can be for a variety of purposes including, but not limited to, examination for health, research, or medical purposes, screening for cancers or tumors, injuries, illnesses, or sicknesses, reproductive conditions, etc. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can be configured as an “endotracheal tube (ET), or other tube, that can have had the appropriate components as described with respect to  FIG. 1 . Certain embodiments of the endoscopes can be applied into normally closed lumens, cavities, and portions of the individual such as via a small incision. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be used, for instance, to determine where such small incisions may be situated, for example. 
     Certain embodiments of the endoscope-based embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  can include, but are not limited to, a rigid or flexible tube  1102 , a light delivery system  1104 , and the Compton scattered X-ray visualizer, imager, or information provider component(s). For instance, certain endoscope-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to include zero, 1, or more emitter portion  150 ; zero, one, or more Compton scattered X-ray receiving assembly  151 ; zero, one, or more detector portion  152 ; and/or zero, 1, or more display portion  154 , as described with respect to  FIG. 1 . Other components component of the Compton scattered X-ray visualizer, imager, or information provider  100  that are not situated in the scope-based embodiment of the Compton scattered X-ray visualizer, imager, or information provider can be included in other associated embodiments of the Compton scattered X-ray visualizer, imager, or information provider. 
       FIGS. 34 to 37  show four embodiments of certain components of the Compton scattered X-ray visualizer, imager, or information provider  100  relative to the at least the portion of the individual  82 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize either wire-based or wireless communications to transfer data between related devices, such as the at least one detector portion  152  and the at least one display portion, as described in this disclosure. In addition, certain networking, computing, imaging, and other well known techniques may be used to facilitate certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure. 
     As described in this disclosure with respect to  FIGS. 34 to 37 , certain embodiment(s) component(s), and/or portion(s) of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as an at least partially external device, while other embodiments can be configured as an at least partially internal device (and/or combination thereof).  FIG. 34  shows one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , in which the at least one emitter portion  150  is situated at least partially externally to the at least the portion of the individual  82 ; while at least a portion of the Compton scattered X-ray receiving assembly  151  is situated at least partially externally to the at least the portion of the individual. 
       FIG. 35  shows one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1 , in which the at least one emitter portion  150  is situated at least partially internally to the at least the portion of the individual  82 ; while the at least a portion of the Compton scattered X-ray receiving assembly  151  is situated at least partially externally to the at least the portion of the individual. 
       FIG. 36  shows one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1 , in which the at least one emitter portion  150  is situated at least partially externally to the at least the portion of the individual  82 ; while the at least a portion of the Compton scattered X-ray receiving assembly  151  is situated at least partially internally to the at least the portion of the individual. For example, as illustrated in  FIG. 35 , certain portions of the at least one Compton scattered X-ray receiving assembly  151  (e.g., corresponding perhaps to the detector portion  152  of  FIG. 1 ), could be at least partially internally applied while other portions of the at least one Compton scattered X-ray receiving assembly  151  (e.g., corresponding perhaps to the display portion  154  of  FIG. 1 ) can be at least partially externally applied. Certain embodiments of wireless, wired-based, data-transfor, image transfer, or other similar mechanism can allow for communication between the internal and external portions of the at least one Compton scattered X-ray receiving assembly  151 . 
       FIG. 37  shows one embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1 , in which the at least one emitter portion  150  is situated at least partially internally to the at least the portion of the individual  82 ; while the at least a portion of the Compton scattered X-ray receiving assembly  151  is situated at least partially internally to the at least the portion of the individual. For example, as illustrated in  FIG. 37 , certain portions of the at least one Compton scattered X-ray receiving assembly  151  (e.g., corresponding perhaps to the detector portion  152  of  FIG. 1 ), could be at least partially internally applied while other portions of the at least one Compton scattered X-ray receiving assembly  151  (e.g., corresponding perhaps to the display portion  154  of  FIG. 1 ) can be at least partially externally applied. Certain embodiments of wireless, wired-based, data-transfor, image transfer, or other similar mechanism can allow for communication between the internal and external portions of the at least one Compton scattered X-ray receiving assembly  151 . 
     There can be a variety of embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  which may utilize a tactile feedback such as to “transfer” some type of feel or touch sensation to the user. Such tactile feedback embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be considered as one embodiment of the tool, as described in this disclosure such as relative to  FIGS. 23 ,  39 , and at other locations, for example. For instance, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may include, or be associated with, that can allow the operator such as a physician to “feel” at least some of the nodules such as to provide an indication as to whether they may be cancerous. The importance of the interrelationship between sight and touch is well-recognized in many health fields. For example, doctors, veterinarians, dentists, assistants, researchers, etc. often provide their analysis of combination of feeling and seeing at least a portion of the individual, in combination. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described in this disclosure, thereby provide considerable sight (at least partially internally and/or at least partially externally) in the form of imaging, visualization, and/or information providing. Such “sight” as can be provider by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be combined with “touch”, which can be provider by certain embodiments of tactile feedback mechanisms. Such embodiments of the tactile feedback mechanism may include various components are mechanisms of automation, tactile feedback, remote-control, robotics, etc., as generally understood in those respective arts, and will not be described more fully in this disclosure. Certain embodiments of the tactile feedback mechanism may be particularly useful when the particular Compton scattered X-ray visualizer, imager, or information provider  100  is being applied at least partially internally to the individual, such that the user cannot always see the internal location. Such tactile feedback embodiments are especially useful for certain doctors, surgeons, veterinarians, dentists, assistants, researchers, etc. with somewhat limited senses of touch and/or sight. 
     In certain instances, the tactile feedback may be partially associated with the diagnosis from a medical user such as a surgeon or doctor. A number of medical diagnosis, examination, treatment, and other practices rely on a combination of sight in combination with touch. It is to be understood that during conventional breast cancer examinations, the “feel” or “touch” of the physician to detect breast cancer nodules in an important portion of examination and/or diagnosis. Proctologists, for example, are often forced to rely on touch or feel, since the ability to see potential medical situations or conditions may be limited. As such, providing certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider with tactile capabilities may be particularly important in the diagnosis or treatment phases. For example, certain doctors may more directly locate or tactilely “feel” for cancers, tumors, or which may be relatively hard as compared with the surrounding matter, nodules, organs, tissue, fat, muscle, or other matter. For dental users, the tactile feedback may by utilized in conjunction with a dental drill or pick, etc., such that the Compton scattered X-ray visualizer, imager, or information provider  100  can be used to indicate the degree and/or area of dental decay, etc. during drilling, etc. It is to be understood that many types of users may similarly benefit from the tactile feedback being provided by certain tools by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be configured to provide a variety of types of tactile feedback. Tactile feedback may be based on hardness or softness of the matter, such as iron or calcium concentration, or concentration of other matter. The tactile feedback system could involve feeding a signal representing some aspect of touchability (e.g., the matter is hard, soft, resilient, etc.) from the tactile system back to the instrument, such as can be displayed, and/or provided as some tactile output to the user. Certain embodiments of the instrument may not be able to “feel” the feedback information in a similar manner as a person, and as such certain tactile output information can be returned from the at least one visualization, image, and/or provided information in image or data form. As such, the user of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider could receive feedback either visually and/or tactically. 
     In addition, certain types of tools can be configured to be actuated based on user input. Such tools may be configured as an endoscope, or alternately some devoted type of tool such as a cutter, gamma knife, scalpel, separator, tactile feedback provider, ablator, surgical suction, etc. Such actuation of at least portions of tool based on user input may be considered as a version of robotics, remote control, amplification, and/or automation. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as allow controlled (e.g., robotic surgery), as well as image processing to precisely detect organs, make incisions, cut matter away, ablate matter, visualize, image, and/or provide information relating to a region in matter, etc. 
     Certain embodiments of the tactile feedback could be provided on a probe or other portion of the Compton scattered X-ray visualizer, imager, or information provider  100  itself, such as in an endoscope. The greater the tactile feedback can enhance certain surgical techniques for surgeons, certain dental techniques for dentists, certain veterinarian techniques for veterinarians, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured as to generate a tactile response that can be detected by a person at least partially in response to the X-ray Compton scattered X-ray information. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be minimally invasive to locate organ, and confirm whether it is at a perceived location. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could allow surgeons, etc. to visualize and/or operate such as to perform more complex surgeries using “keyholes”, or incisions, within the patient. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  with tactile feedback can be configured to visualize, image, and/or provide information from a location at least partially external to the at least the portion of the individual. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider with tactile feedback can be configured to visualize, image, and/or provide information from a location at least partially internal to at least the portion of the individual (either via a normally open location such as using an endoscope or via a normally closed location such as with an incision). 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could therefore be utilized for a variety of applications and Compton scattered X-ray visualization, imaging, or information providing techniques outside of scope of confessional X-ray. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could be situated, or made viewable to the at least the portion of the individual at their bedside such as they may view. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be utilized as a relatively inexpensive alternative to MRI, for example, which doesn&#39;t necessarily enclose the body of the at least the portion of the individual as is the case with MRI, CT, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may therefore serve as a direct replacement, in certain applications, for such imaging technologies as MRI, CT, etc. In addition, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be preferred, in certain applications, to ultrasound because of the considerable contrast of the Compton scattered X-ray visualizer, imager, or information provider. 
     As described in this disclosure, certain embodiments of the emitter portion  150  may be at least partially steerable. Additionally, certain embodiments of the detector portion  152  may be at least partially adjustable to control the direction which it best receives X-ray-based electromagnetic radiation. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may therefore be configured such that the emitter portion  150  is relatively closely aligned with the detector portion  152 . Similarly, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  may be configured to such that the emitter portion  150  moves into an approximate alignment with the detector portion  152 , in certain embodiment as to create a standing pattern such as may be utilized to visualize, image, and/or provide information relating to a region utilizing scanning, such as is generally known with certain display technologies. By utilizing such scanning embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , relatively good-quality Compton scattered X-ray visualization, imaging, or information providing can be provided. Additionally, relatively low power may be necessary (as compared to other medical imaging modalities), such as may be useful in limiting the exposure of the at least the portion of the individual to relatively high-powered X-rays, as described in this disclosure. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to identify a trend of pattern correlating to the change in state to a pattern corresponding to a macrostate. These patterns can be correlated to a target indicative of a particular condition. By comparing the visualized, imaged, or information provided pattern with the pattern recognized as representaing a condition, illness, etc. The information, data, patterns, etc. can be maintained in a database, the pattern of information can be used for a prognosis of the condition, illness, etc. The use of information, data, patterns, etc. as can be received by or pr processed from scattered X-ray from Compton scattered X-ray can therefore be quite useful for a variety of purposes. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to use selected portion of new slice info, and higher resolution info to produce composite visualize, image, and/or provide information (having enhanced resolution) as compared to original visualizations, images, or provided information. Also, producing this can be responsive to matter deformation modeling. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to consider information that can be not only anatomically obtained, but also functionally obtained. (Instead or in addition to displaying info, correlate to a bio-state, or change in state. Change in state from a plurality of locations). 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured such as their at least one emitter portion  150  and their at least one detector portion  152  integral to a tool (surgical, examination, positioning, scope-type, tactile feedback provider, luminal, etc.). In certain instances, the Compton scattered X-ray visualizer, imager, or information provider  100  may provide a proximity sensor function to the tool. For example, the at least one emitter portion  150  may be sized such as to emit (in substantially 4π or 2π steradians) at a desired frequency and/or energy level based on the depth that is being examined or that the tool is being positioned, and the detector portion may be a pixellated X-ray detector portion array, an avalanche detector array, a CCD array, etc. Examples of X-ray detectors may include, but are not limited to, pixellated streak cameras, streak cameras, CCD devices, avalanche detectors, or other devices. With certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , the emitter portion may produce a beam, where the detector portion is not a pixellated array (e.g., including a Kulikov lens, and/or a Bragg lens). Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might include the emitter portion at the distal end of the tool, and the detector portion separated there from either in close proximity or by a considerable distance in a manner desirable to provide suitable Compton scattered X-ray visualization, imaging, or information providing. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  might be particularly useful if positioned on, integrated into, or otherwise associated with the tool (e.g., situated on the tip of a probe or cutter, on at least one tip of scissors, on forceps, on needles, etc.).  FIG. 39 , for example, illustrates one embodiment of the tool (surgical knife) including an embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100 . For the purpose of this disclosure, certain endoscopes as described with respect with  FIG. 23  can be considered as tools that can include certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of tools may also be associated with a tactile feedback mechanism that provides at least some tactile feedback, which by themselves may be considered as another embodiment of tool within this disclosure. It may therefore be desirable to position certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  on, proximate to, or to provide viewability of, operative surfaces of a variety of such tools as surgical tools, tactile feedback providers, etc. Such embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby provide a visualization, imaging, or information providing from the viewpoint of the tool. 
     Implants, constructs, pins, screws, etc. such as may be positioned within the individual may be considered as one embodiment of the tool, which may include certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Additionally, certain implants, constructs, pins, screws, etc. can be viewed as tools that in include certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can provide an added benefit, such that when a user such as a surgeon is placing a pedicle screw, it is highly desired to stay within the pedicle because if the surgeon goes outside they may contact a nerve root. As such, the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  can act as a pedicle guide. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be considered to combine with a warning system that can utilize certain embodiments of the depth visualizing, imaging, or information providing controller  97 . Certain embodiments of the depth visualizing, imaging, or information providing controller  97  can include, as data or information, a variety of individual information, such as patient information, injury, illness, and if the user (doctor, dentist, veterinarian, etc.) is positioning the tool at an undesired location or performing some undesired procedure (e.g., at the wrong side of the patient&#39;s body), in which instance a suitable alarm may be actuated in the event of a suitable event. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be configured as a surgical tool, certain of which may be configured to act as a proximity sensor, while output from others may be displayed. It is envisioned that the emitter portion  150  and/or the Compton scattered X-ray receiving assembly  151  could be integral to the surgical tool and/or tactile feedback provider. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to image once multiple times, or can include a number of or at least one displaceable emitter portion(s) to provide scanning. In certain instances, upon the surgical tool being positioned relative to the at least the portion of the individual is configurable to emit X-ray based electromagnetic radiation suitable to image to a controllable depth into an at least one matter of at least a portion of the individual to be used to derive depth visualizations, images, or provided information at least partially in response to Compton scattered X-ray of the X-ray based electromagnetic radiation. The detector portion may also be integral to the surgical tool and/or tactile feedback provider that is operable, and as such may be alignable and/or controllable. Certain embodiments of the emitter portion may include scopes, but may also be at least partially externally situated. Certain of the at least partially internal embodiments may be inserted through insertion or via a normally open opening to be at least partially applied relative to at least a portion of the individual such as to receive at least one Compton scattered X-ray that has been Compton scattered in an at least one matter, etc. of the at least the portion of the individual. 
     Certain embodiments of the visualization, imaging, or information providing controlling  97  are configured particularly to generate the depth visualizations or images that can be displayed over the display portion  154  of the Compton scattered X-ray visualizer, imager, or information provider  100 , as described with respect to  FIG. 1 , and other locations through this disclosure. By comparison, certain embodiments of the visualization, imaging, or information providing controlling  97 , as described with respect to  FIG. 38 , can be configured to produce information that can be displayed over certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , which can be observed by the user and/or individual (human). Consider, for example, the embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  that can scan individuals for such aspects as cancers (e.g., breast cancer, melanomas), tumors, blood vessel locations (perhaps in diabetics to provide insulin shots), heart condition, bone fragments or portions (especially useful at certain sporting events, etc.), burn victim examination, and/or a variety of emergencies or situations which a variety of emergency, rescue, medical, as well as individuals who wish to examine themselves at locations remote from conventional imaging equipment are likely to encounter. 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider can utilize lower power requirements and conventional imagers since they rely on Compton scattered X-ray of X-rays instead of transmission X-rays (i.e., the latter requires providing enough energy to the X-ray photons to pass the X-ray photons through the image portion of the individual, instead of scattering within the individual as with the former). Since less energies required for typical operation of the Compton scattered X-ray depth and visualizer, imager, or information provider  100 ; they can thereby be configured to operate with reduced input voltages. It is feasible that certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be made to use power supplies a medical clinics, homes, offices, vehicles, etc. and can thereby be made considerably more portable than conventional imaging equipment. 
     By allowing certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to operate using relatively low power as compared to conventional imaging systems, is likely that the visualization, imaging, and/or information providing systems can be utilized in regions remote from sophisticated electrical infrastructure. As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be applied to remote medical facilities, or regions, sporting events, office locations, relatively poor or remote regions, villages, islands, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby be situated where the medical, dental, rescue, emergency, or other need is (e.g., where sick, injured, or other individuals to be examined may be situated), as compared to where relatively large power supplies or complex or expensive imaging equipment may be located. 
     As such, certain portable embodiments of the at least the portion of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize such portable energy-provided devices as fuel cells, batteries, generator, etc. By allowing a wide range of portable energy sources, such as allowed by relatively low power usage by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , relatively portable embodiments of visualizing, imaging, or information providing solutions can be provided. 
     As such, certain user-operated embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be used in, and are designed to be suitable to be used in, the particular location of the user (e.g., doctor&#39;s office, operating room, emergency center, rescue vehicle, ambulance, dentist office, veterinarian, a vehicle, the individual&#39;s home or office, a remote village, etc.) to visualize, image, and/or provide information at least a portion of the individual, or receive information relating to the individual. Certain individual-operated, home-based, office based, or other remote embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be used in, and are designed to be suitable to be used in) the home, office, or other location of the user that can be used by the user (who may be the individual) as a home-style version to visualize, image, and/or provide information at least a portion of the individual, or receive information relating to the individual. The different user-operated or individual-operated embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can each have varied functions and/or operations. 
     Considering the privacy issues, and the time required for patients to visit doctors, etc., the individual-operated embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to allow people, and other individuals, to monitor a variety of aspects of their own condition. Consider the privacy, flexibility, independence, and other benefits that home pregnancy tests have provided for women. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to provide depth visualization, images, and/or associated information related to a variety of other conditions, illnesses, injuries, sicknesses, and other conditional, medical, and/or routine check-up aspects. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  could even be designed based, at least partially, on X-ray radiation limiting, user input, ergonomics, quality of imaging, and other such factors; and might be updated, improved, and changed as appropriate based on usage and feedback considerations. 
     Certain embodiments of the individual-operated embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to be devoted to only one, or a relatively few, devoted task (e.g., cancer or tumor scans, blood vessel locator, bone fragment detector, etc.). By being devoted to a few specific tasks, these devoted embodiments of the individual-operated embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be made relatively inexpensively, and relatively simple, for the individual and/or other person using it. Consider that patients, family members, friends, etc. would typically be expected to have relatively little training and/or experience with imaging systems, and a such, such embodiments should be made relative straight forward to understand with relatively little training. 
     By applying certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  to conventional imaging equipment, certain devoted tasks, logic, computer programming, electronic circuitry, and/or other processing circuitry can make relatively clear analysis, determinations, prognosis, etc. as compared certain relatively expensive and multi-use conventional imaging equipment such as MRIs and CAT scan devices. As such, a particularly exemplary embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured for a particular of a few devoted operations such as examining for such conditions, illnesses, or injuries as melanomas, cancers, tumors, bone condition, tissue condition, ligament or tendon condition, etc. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be designed, for example, to scan region of the individual for such aberrations as they may occur. 
     Thereupon, certain embodiments of the visualization, imaging, or information providing controller  97  can be configured to determine logically (using a combination of hardware, software, firmware, as described in this disclosure) whether the condition falls within limits as to require further examination, for example. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to provide such devoted tasks with output in the form of imaging and/or visualization. Although certain embodiments of these devoted devices can more suitably, and less expensively, output one or more of a variety of information resulting at least partially from some analysis and processing in a non-image-based mode (e.g., text, graphics, analysis output, etc.) which could be of considerable use both to trained and/or untrained users. 
     There are a variety of techniques by which certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can visualize, image, or provide information to within a depth substantially scattered range to a prescribed substantially scattered depth in at least some matter of the at least the portion of the individual. Certain of these techniques are illustrated in  FIGS. 40 and 41 , for example. 
       FIG. 40 , for example, illustrates an embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can visualize, image, or provide information to within the depth substantially scattered range to between the prescribed substantially scattered depth  168 ,  170   a ,  170   b  in at least some matter of the at least the portion of the individual by applying a number of applied X-rays  120   m ,  120   n , and  120   o  that respectively scatter at respective scattering events sitated at differing respective prescribed substantially scattered depth  168 ,  170   a ,  170   b  to provide respective scattered X-rays  122   m ,  122   n , and  122   o . Though the number of applied X-rays  120   m ,  120   n , and  120   o  are illustrated as being applied at different angles (such as from multiple emitter portions are different angles, or from a single emitter portion through several collimators), it should be understood that though these applied X-rays  120   m ,  120   n , and  120   o  can be applied parallel or spaced from each other, such as being provide from an array. The respective scattered X-rays  122   m ,  122   n , and  122   o  can be detected by certain embodiments of the Compton scattered X-ray receiving assembly  151 . 
       FIG. 41 , for example, illustrates an embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can visualize, image, or provide information to within the depth substantially scattered range to between the prescribed substantially scattered depth  168 ,  170   a ,  170   b  in at least some matter of the at least the portion of the individual by the at least one emitter portion  150  applying a single applied X-ray  120   p  that scatters at respective scattering events sitated at differing respective prescribed substantially scattered depth  168 ,  170   a ,  170   b  to provide respective scattered X-rays  122   p ,  122   q , and  122   r . The respective scattered X-rays  122   p ,  122   q , and  122   r  can be detected by certain embodiments of the Compton scattered X-ray receiving assembly  151 . 
     Certain characteristics of electromagnetic waves, currents, flows, fields, etc. (including aspects relating to X-rays, X-ray photons, electrons, etc.) is described in  The Electrical Engineering Handbook, Second Edition , Richard C. Dorf, CRC Press/IEEE Press, (incorporated herein by reference in its entirety). Certain types of X-rays, which may be characterized broadly as electromagnetic waves, particles, fields, currents, etc., can be controlled, adjusted, varied, weakened, intensified, directed, etc. utilizing certain shielding, shaping, and/or electromagnetic controller techniques; such as are generally understood by those skilled in electrical engineering and/or electromagnetics. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize X-rays, electromagnetic signals, particles, waves, etc. for Compton scattered X-ray visualization, imaging, or information providing. 
     2. Controllable and/or Adjustable Embodiments of the Compton Scattered X-ray Visualizer, Imager, or Information Provider 
     As described with respect to  FIG. 1 , certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can direct the applied X-ray  120  toward matter underneath a surface of at least a portion of the individual. The applied X-ray can be scattered by the matter of the at least a portion of the individual based on Compton scattered X-ray aspects and equations, as described in this disclosure. Based upon the amount of Compton&#39;s scattering, the energy level loss of the X-ray photons during the scattering event, and other such scattering characteristics, can be considered during Compton scattered X-ray visualization, imaging, or information providing. In certain instances, the energy level of the X-ray photons being applied to the matter of the individual can be ramped up, decreased, modified, maintained, etc. as described in this disclosure with respect to  FIGS. 42 to 45 . Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby visualize, image, or provide information relating to particular matter based at least partially on increasing, reducing, modifying, or maintaining the energy levels of the X-ray photons (and thereby conversely decreasing the frequency of the X-ray photons) included in the applied X-rays, and thereby controlling and/or adjusting the operation of the Compton scattered X-ray visualizer, imager, or information provider. As the energy level of the X-ray photons respectively increases or decreases, within the at least one visualizing, imaging, or information providing depth range to the at least one prescribed visualizing, imaging, or information providing depth of a considerable majority of the photons can thereupon generally respectively increase or decrease, though not typically in a linear fashion. 
     While the embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  as described with respect to  FIGS. 42-45  illustrate the at least one emitter portion  150  whose output is controlled by an additional device; in actuality the distinct added device can be considered as an integral portion of the at least one emitter portion. As such, certain embodiments of the at least one emitter portion may be considered as configured to apply adjustable and/or controllable applied X-rays toward the at least some matter of the at least the portion of the individual. 
     As described above, there can be a variety of mechanisms that can be used to adjust and/or control certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 , largely based on operation of the visualization, imaging, or information providing controller  97  to control and/or adjust the energy level, frequency, or other characteristics of the X-ray photons included in the applied X-ray  120 . There are other mechanisms which may be utilized to control and/or adjust this depth visualizing, imaging, or information providing of certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . 
     The modification, control, adjustment, etc. in the characteristics of Compton scattered X-ray visualization, imaging, or information providing into the matter of the at least the portion of the individual may not necessarily follow a linear function relative to the increasing energy levels of the X-ray photons making up the applied X-rays. In addition, since the matter of such individuals is not homogenous, the rate of Compton scattered X-ray visualization, imaging, or information providing may vary as a function of the material within the individual being imaged. For example, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured for imaging at least partially through bone would be expected to differ considerably (e.g., requiring different, likely increased, energy levels of the photons) as compared to the imaging characteristics required for less dense matter such as tissue, fluids such as blood or water, tumors, gums, various organs, etc. As such, certain embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to adjust and/or control the at least one visualizing, imaging, or information providing depth range to the at least one prescribed visualizing, imaging, or information providing depth such as by using a variety of techniques as described in this disclosure. 
       FIG. 42  shows another embodiment of the control or adjustment mechanism  302 , in which an anode switching or modifying mechanism (e.g., to include an adjustable anode wheel, or varying photon generator, as described with respect to  FIG. 8  or  9 ) can allow for physically altering or changing of the anode  834 . Certain embodiments of the anode  834  have been described with respect to  FIG. 8  or  9 . For instance, the anode wheel has been described with respect to  FIG. 8 , and is described with respect to  FIG. 42 . The anode wheel can be rotated (e.g., using a step or motor, etc.), such as to align a different anode such as might have different materials, configurations, and/or dimensions, etc. such as to allow a change in the anode that is in communication with the electron stream, thereby providing varied energy levels (e.g., frequencies of X-ray photons) for the applied X-ray  120 . Certain embodiments of the anode wheel  4202  can be rotated or displaced about an axis  4204 , such as by using a stepper motor or other suitable actuator, such as to operably position at least one anode  834  of the desired material, size, shape, configuration, etc. within the emitter portion as desired. Positioning an anode having the desired characteristics within the emitter portion as described with respect to  FIG. 8  effectively generates the applied X-rays having the desired characteristics (e.g., X-ray photon energy level and corresponding frequency). Additionally, certain embodiments of the photon generator  880 , as described with respect to  FIG. 9 , can be configured to provide X-ray photons having varied intensities and/or frequencies, such that could be used to control and/or adjust certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100 . For example, the photon generator as described with respect to  FIG. 9  could include multiple distinct photons generators, each of which could be individually actuated as to provide a controllable and/or adjustable version of the applied X-ray  120  having the desired X-ray photon frequency and/or energy level characteristics. 
       FIG. 43  shows another embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  including one embodiment of a control or adjustment mechanism  302  that can be utilized by certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider, in which the angle of the applied X-ray  120  can be adjusted or controlled by being angled relative to the surface  168  of the at least the portion of the individual  82 . As the angle of the applied X-ray  120  changes, the at least one visualizing, imaging, or information providing depth range to the at least one prescribed visualizing, imaging, or information providing depth can vary as a cosine function of the angle. As such, increasing the angle of the applied X-ray can therefore reduce the at least one visualizing, imaging, or information providing depth range to the at least one prescribed visualizing, imaging, or information providing depth in a predictable, adjustable, and/or controllable fashion. 
       FIG. 44  shows another embodiment of the Compton scattered X-ray visualizer, imager, or information provider  100  including another embodiment of the control or adjustment mechanism  302 , in which an X-ray depth-imaging depth reducing mechanism can be operationally applied between the emitter portion  150  the surface of the at least the portion of the individual (or at some other locations) as to limit the at least one depth substantially scattering range to the at least one prescribed substantially scattering depth to reduce the energy level of the X-ray photons being applied to the at least the portion of the individual. Consider that, in general, as the applied X-rays  120  travel through the matter of the at least the portion of the individual, they typically lose energy. As such, the X-ray depth-imaging depth reducing mechanism can be configured is any device or mechanism that can similarly reduce the energy level of the X-ray photons of the applied X-ray prior to being applied to the at least the portion of the individual. Certain embodiments of the adjustment or control mechanism  44  as illustrated in  FIG. 44  could include an X-ray energy level or frequency modulator or modifier. 
     As such, the effective at least one substantial scattering within the at least one substantially scattering depth range to the at least one prescribed substantially scattering depth  120  can enter into the matter of the at least the portion of the individual can be reduced by initially passing through certain embodiments of the X-ray depth-imaging depth reducing mechanism can be reduced. Certain X-ray depth-imaging depth reducing mechanism to embodiments of the control or adjustment mechanism  302  can effectively decrease the energy level and/or frequency of the X-ray photons included in the applied X-rays  120 . Various X-ray depth-imaging depth reducing mechanism to arrange for a layer of material that at least partially dissipates the energy of the X-ray photons, to at least one semiconductor device or other mechanism that can modulate X-ray frequencies and thereby reduce energies, etc. 
       FIG. 45  shows another embodiment of the adjustable or controllable mechanism  302  by which a variety of filters would be applied to the applied X-ray to filter out at least certain frequency X-rays, while allowing at least other frequency X-rays to pass. Certain embodiments of the emitter portion  150  thereby can include multiple X-ray generators, multiple anodes, or multiple devices that each can generate X-rays photons having a distinct frequency. Alternately, certain embodiments of the emitter portion  150  can generate a broadband X-ray including X-rays having a range of frequencies, only certain ones of which are allowed to pass through the filter embodiment of the adjustment or control mechanism  302 . For instance,  FIG. 45  shows one filtering embodiment of the adjustment or control mechanism  302  that allows X-ray photons having frequency corresponding to applied X-ray  120   x  to pass, while limiting the ability of X-ray photons having frequencies corresponding to applied X-rays  120   y  and  120   z  to pass. 
     There are therefore a variety of configurations of various embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can include a variety of types of adjustment or control mechanism  302  by which the energy level of X-ray photons can be controlled or adjusted. Certain embodiments of the at least one emitter portion  150  and/or the at least one Compton scattered X-ray receiving assembly  151  can be configured in arrays, or by having slightly different operating characteristics. As such, one or more of the at least one emitter portion  150  and/or the at least one Compton scattered X-ray receiving assembly  151  can be actuated and/or deactuated, depending on characteristic, position, angle, etc. such as to allow for control and/or adjustment of the visualizing, imaging, or providing information modalities. 
     Additionally, certain embodiments of the Compton scattered X-ray receiving assembly  151  can be directed, positioned, angled, filtered, or otherwise operated to only receive certain scattered X-rays. While these embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  are not illustrated, it is to be understood that certain embodiments of the adjustment or control mechanism  302  can be situated relative to the at least one emitter portion  150 , relative to the at least one Compton scattered X-ray receiving assembly  151 , at some median location, or elsewhere. Certain embodiments of the adjustment or control mechanism  302  can be software, hardware, firmware, and/or processor intensive such as to only consider certain of the scattered X-rays as received by certain embodiments of the Compton scattered X-ray receiving assembly  151 . 
     The various exemplary embodiments of the adjustment or control mechanism  302  as described with respect to  FIGS. 42 to 45  are intended to be illustrative in nature, but not limiting in scope. Any of a variety of techniques by which the frequency (and the corresponding energy level) of the X-ray photons of the applied X-rays being applied to the at least some matter of the at least a portion of the individual may be considered as another embodiment of the adjustment or control mechanism, within the scope of the present disclosure. 
     Additionally, certain embodiments of the adjustment or control mechanism can be applied to respectively adjust or control the X-ray photons of the scattered X-ray  122  being scattered from the scattering event within the matter of the at least the portion of the at least a portion of the individual. A variety of such adjustment or control techniques such as filtering, correlating, controlling, or selectively monitoring certain X-ray photon frequency or energy levels of the scattered X-rays. 
     There may be some of the X-ray photons of the applied X-ray that are being altered such as by ramping, reducing, modification, maintaining, in which the applied X-rays is applied into the matter of the individual can scatter within the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth for that particular or instantaneous visualizing, imaging, or information providing period. Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can be configured to limit the effects of the X-ray photons of the Compton scattered X-rays  120  that are returning from a depth greater than the within the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth. Additionally, the depth visualizing, imaging, or information providing effects of these X-ray photons of the Compton scattered X-rays  120  can be included in the Compton scattered X-ray visualization, imaging, or information providing, with any distortive effects during the ramping operation either ignored, filtered, and/or otherwise limited using signal processing techniques. 
     Such increase or ramping of the energy level of the applied X-ray can be performed by those embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  that can be tuned. The rate of ramping (e.g., the rate of the photon energy level) can thereby be set or controlled either manually or by setting the visualization, imaging, or information providing controller  97 . Experimentation could be used to provide an indication of a suitable ramping rate for the particular matter(s) of the at least the portion of the individual. 
     With a ramping function, each increase in the energy of the X-ray photons of the applied X-ray such as would be expected to provide an increased in the within the at least one substantially scattered depth range to the at least one prescribed substantially scattered depth can be monitored by the Compton scattered X-ray receiving assembly.

     3. Certain Embodiments of the Visualization, Imaging, or Information Providing Controller 
     This disclosure describes a number of embodiments of the visualization, imaging, or information providing controller  97  as described with respect to  FIG. 1 , which is intended to control and/or adjust Compton scattered X-ray visualization, imaging, or information providing by the Compton scattered X-ray visualizer, imager, or information provider  100  of at least the portion of the individuals  82 . As such, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can operate without, and/or with little interaction from, the visualization, imaging, or information providing controller  97 . By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize considerable input from, and/or entirely utilizing input from, the visualization, imaging, or information providing controller  97 . 
     Certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can thereby include the visualization, imaging, or information providing controller  97  as described with respect of  FIG. 1 ; while other embodiments of the Compton scattered X-ray visualizer, imager, or information provider may not include utilizing the visualization, imaging, or information providing controller. For example, certain scintillator-based and/or fluoroscope-based embodiments of the Compton scattered X-ray visualizer, imager, or information provider may convert received X-ray based photons directly into viewable and/or visible photons (which may or may be amplified using a photomultiplier or CCD) to allow direct Compton scattered X-ray visualization, imaging, or information providing, which may limit the necessity of image processing that may largely rely on the visualization, imaging, or information providing controller  97 . By comparison, certain embodiments of the Compton scattered X-ray visualizer, imager, or information provider  100  can utilize input from the user, such as to determine location, angle, position, resolution, X-ray frequency, energy level, time of depth visualizing, imaging, or information providing, and other such Compton scattered X-ray visualization, imaging, or information providing related factors or characteristics. Such Compton scattered X-ray visualization, imaging, or information providing characteristics may be selected, controlled, and/or altered using certain embodiments of the visualization, imaging, or information providing controller  97 .

     Those having skill in the art will recognize that the state of the art in computer, controller, communications, networking, and other similar technologies has progressed to the point where there is little distinction left between hardware, firmware, and/or software implementations of aspects of systems, such as may be utilized in the Compton scattered X-ray visualizer, imager, or information provider. The use of hardware, firmware, and/or software can therefore generally represent (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle can vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer and/or designer of the Compton scattered X-ray visualizer, imager, or information provider may opt for mainly a hardware and/or firmware vehicle. In alternate embodiments, if flexibility is paramount, the implementer and/or designer may opt for mainly a software implementation. In yet other embodiments, the implementer and/or designer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible techniques by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle can be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary.
