DETAILED DESCRIPTION FIG. 1 is a schematic view showing one embodiment of a system according to the present invention. In the embodiment shown in FIG. 1, indicia 20 are structural frames, some of which contain reflective elements, some of which contain LED active elements, some of which can contain both, for tracking using stereoscopic infrared sensors suitable, at least operating in concert, for sensing, storing, processing and/or outputting data relating to (�tracking�) position and orientation of indicia 20 and thus items 104 or body parts 120 to which they are attached or otherwise associated. Position sensor 106 may be any sort of sensor functionality for sensing position and orientation of indicia 20 and therefore items with which they are associated, according to whatever desired electrical, magnetic, electromagnetic, sound, physical, radio frequency, or other active or passive technique. In the embodiment shown in FIG. 1, computing functionality 112 can include processing functionality, memory functionality, input/output functionality whether on a standalone or distributed bases, via any desired standard, architecture, interface and/or network topology. In this embodiment, computing functionality 112 is connected to a monitor 110 on which graphics and data may be presented to the surgeon during surgery. The screen preferably has a tactile interface so that the surgeon may point and click on screen for tactile screen input in addition to or instead of, if desired, keyboard and mouse conventional interfaces. Additionally, a foot pedal 24 or other convenient interface may be coupled to functionality 112 as can any other wireless or wireline interface to allow the surgeon, nurse, or other desired use to control or direct functionality 112 in order to, among other things, capture position/orientation information when certain components are oriented or aligned properly. Computer functionality 112 can process, store and output on monitor 110 and otherwise various forms of data which correspond in whole or part to items 104. The computer functionality 112 can also store data relating to configuration, size and other properties of items 104 such as implements, instrumentation, trial components, implant components and other items used in surgery. Additionally, computer functionality 112 can track any point in the position/orientation sensor 106 field such as by using a probe 8. The probe can also contain or be attached to indicia 20. The surgeon, nurse, or other user touches the tip of probe 8 to a point such as a landmark on bone structure and actuates the foot pedal 24 or otherwise instructs the computer 112 to note the landmark position. The position/orientation sensor 106 �sees� the position and orientation of the indicia 20 �knows� where the tip of probe 8 is relative to the indicia 20 and thus calculates and stores, and can display on monitor 110 whenever desired in whatever form or fashion or color, the point or other position designated by probe 8 when the foot pedal 24 is hit or other command is given. Thus, probe 8 can be used to designate landmarks on bone structure in order to allow the computer 112 to store and track, relative to movement of the bone indicia 20, virtual or logical information such as mechanical axis 28, medial lateral axis 32 and anterior/posterior axis 34 of body part 120 in addition to any other virtual or actual construct or reference. In the embodiment shown in FIG. 1, images of body part 120 are obtained using imaging functionality 108 attached to indicia 20. The probe 8 also has indicia 20 attached. A surgeon aligns the probe 8 along the position of the desired axis 30 for imaging and the foot pedal 24 is activated. The position/orientation sensor 106 �sees� position and orientation of the indicia 20 attached to the body part 120 and also the position and orientation of the indicia 20 attached to the probe 8 whose tip is touching a landmark on body part 104 and thus can calculate the desired axis 30 for imaging. The computer stores the desired axis 30 with this position/orientation information. The imaging functionality 108 with indicia 20 attached then moves to the position and location stored in the computer functionality 112 that was previously defined by the probe 8. An image is then taken along the desired axis 30. Similarly, the mechanical axis and other axes or constructs of body parts 104 can also be �registered� for tracking by the system and subsequent imaging. The surgeon uses the probe to select any desired anatomical landmarks or references at the operative site. These points are registered in three dimensional space by the system and are tracked relative to the indicia on the patient anatomy. After the mechanical axis and other rotation axes and constructs relating to the body parts are established, imaging apparatus can be used to capture images along these axes. Additionally, probe 8 can be used to define a plurality of desired axes. A surgeon positions the probe 8 along the desired axis, or to designate the landmark or landmarks along which he would like images taken in sequence. At the site of each desired image, the surgeon activates the foot pedal or other actuator and stores the position and orientation data for each axis in the computer. The computer then uses this stored information to direct the imaging apparatus to the correct location to capture each desired image. FIGS. 2 and 3 schematically show one embodiment of the present invention. FIG. 2 shows a probe 8 that includes indicia 20 in the form of fiducials. The probe 8 is attached to a body part 120 along an axis 30 for which an image is desired. The probe 8 is positioned to indicate the desired axis 30 along which the image will be taken. FIG. 3 shows the imaging device 108 positioned to capture the desired image of the body part 120 of FIG. 2 along the axis 30 defined by the probe 8. Alternatively, as shown in FIG. 3A, the probe 8 may be removed. The desired axis 30 on which the image is to be taken has been stored in the computer functionality. An imaging apparatus 108, in this embodiment shown as a C-arm, is positioned using the data stored in the computer functionality in the correct position and orientation to capture the image desired by the axis 30 provided by the probe. This positioning can be accomplished manually using information stored in the system, and/or the computer can automatically position the C-arm using information stored in the system, at least some of which includes information generated with the use of probe 8. While FIGS. 2 and 3 depict one embodiment of the present invention, the invention includes any navigation alignment system which allows a user to establish or input desired axes for images into a computer-aided navigation system through the use of probes which have fiducials sensed by the system. The foregoing is provided for purposes of disclosure of various aspects and embodiments of the present invention. Changes, deletions, additions or and substitutions may be made to components, combinations, processes, and embodiments disclosed in this document without departing from the scope or spirit of the invention.
