Section: claims

1. A masking assembly for partially masking a specimen that is subject to radiation imaging, comprising:sections of radiation blocking material connected to define a specimen holding frame and a single imaging window within the specimen holding, frame exposing the specimen to the radiation;wherein the sections of radiation blocking material further define an interior region that is so dimensioned to receive exterior contours of the specimen against internal faces of the holding frame,wherein the internal faces of the holding frame are separate from other faces of the holding frame defining the imaging window, andwherein at least a portion of the specimen is visible through the imaging window. 2. A masking assembly according to claim 1, wherein the internal faces of the sections track at least one profile of the specimen, the faces defining at least one void between at least one surface of the specimen and the masking assembly. 3. A masking assembly according to claim 2, wherein the internal faces connect to the exterior contours of the specimen to define a gap that is within a tolerance measurement. 4. A masking assembly according to claim 2, wherein the internal faces connect at an angle configured to be open toward the interior region and so dimensioned to receive the specimen within the angle. 5. A masking assembly according to claim 1, wherein the internal faces are configured to extend over a portion of the exterior contours of the specimen. 6. A system for imaging a specimen with radiation, the system comprising:a source of radiation to be directed to the specimen;a filter between the source of radiation and the specimen to attenuate the radiation to a preferred power and wavelength;a masking assembly for partially masking the specimen, the masking assembly comprising:sections of radiation blocking material connected to define a specimen holding frame and an imaging window within the specimen holding frame,wherein the sections of radiation blocking material further define an interior region that is so dimensioned to receive exterior contours of the specimen against internal faces of the holding frame,wherein the internal faces of the holding frame are separate from other faces of the holding frame defining the imaging window, andwherein at least a portion of the specimen is visible through the imaging window. 7. A system according to claim 6, further comprising a digital imaging device comprising an imaging surface configured to receive the specimen surrounded by the masking assembly thereon,wherein the internal faces of the sections track at least one profile of the specimen, the faces enclosing at least one void between at least one surface of the specimen, the masking assembly, and the digital imaging device. 8. A system according to claim 7, wherein the digital imaging device further comprises a direct digital array receiving the radiation from the source, wherein the radiation traverses the imaging window of the masking assembly, the specimen, and is exposed to an imaging surface of the direct digital array. 9. A system according to claim 7, wherein the filter, the masking assembly, and the digital imaging device are configured to utilize the lowest power level of the radiation source to achieve an image of the specimen. 10. A method of masking a specimen for radiation imaging, comprising:attaching sections of radiation blocking material to one another such that the connected sections define a specimen holding frame and an imaging window within the specimen holding frame,arranging the sections of radiation blocking material to further define an interior region that is so dimensioned to receive exterior contours of a specimen against internal faces of the holding frame,wherein the internal faces of the holding frame are separate from other faces of the holding frame defining the imaging window, andwherein at least a portion of the specimen is visible through the imaging window. 11. A method according to claim 10, wherein the internal faces of the sections track at least one profile of the specimen, the faces defining at least one void between at least one surface of the specimen and the masking assembly. 12. A method according to claim 10, wherein the internal faces connect to the exterior contours of the specimen to define a gap that is within a tolerance measurement. 13. A method according to claim 10, wherein the internal faces define at least one angle that overlaps the specimen. 14. A method according to claim 10, further comprising dimensioning the masking assembly such that upon placing the specimen and the masking assembly on an imaging surface, the arrangement of the masking assembly, the imaging surface, and the exterior surfaces of the specimen enclose at least one void defined by the arrangement. 15. The system according to claim 6, further comprising additional sections of radiation blocking material that eliminate the imaging window, wherein the specimen is surrounded by radiation blocking material. 16. The system according to claim 15, wherein the holding frame blocks particular portions of radiation and is permeable to desired portions of radiation necessary for imaging.
