Abstract

A specimen radiography system may include a controller and a cabinet. The cabinet may include an x-ray source, an x-ray detector, and a specimen drawer disposed between the x-ray source and the x-ray detector. The specimen drawer may be automatically positionable along a vertical axis between the x-ray source and the x-ray detector.

First claim

What is claimed is:

1. A specimen radiography system comprising:
a controller; and
a cabinet operably coupled to the controller, the cabinet comprising:
an x-ray source;
an x-ray detector; and
a specimen drawer configured to support a tissue specimen, the controller controlling relative positions between the x-ray source and the specimen drawer within the cabinet for obtaining (1) two or more projection images of the tissue specimen to generate a 3D data set of the tissue specimen, and (2) at least one magnification image of the tissue specimen.

2. The specimen radiography system of claim 1 , wherein the x-ray source and the x-ray detector are aligned along a vertical axis, and wherein the specimen drawer is rotatable around the vertical axis and movable along the vertical axis.

3. The specimen radiography system of claim 2 , wherein the specimen drawer rotates around the vertical axis between the two or more projection images of the tissue specimen.

4. The specimen radiography system of claim 2 , wherein the specimen drawer moves along the vertical axis for the at least one magnification image of the tissue specimen.

5. The specimen radiography system of claim 1 , wherein the specimen drawer is configured to extend from the cabinet.

6. The specimen radiography system of claim 1 , wherein the x-ray source is rotatable in an arc around the specimen drawer between the two or more projection images of the tissue specimen.

7. The specimen radiography system of claim 6 , wherein the cabinet further comprises a radial guide track or a pivoting elongated arm, and wherein the x-ray source is coupled to the radial guide track or the pivoting elongated arm.

8. The specimen radiography system of claim 1 , wherein the specimen drawer tilts relative to the x-ray source between the two or more projection images of the tissue specimen.

9. The specimen radiography system of claim 8 , wherein the x-ray source is rotatable in an arc around the specimen drawer between the two or more projection images of the tissue specimen.

10. The specimen radiography system of claim 1 , wherein the x-ray source and the x-ray detector are rotated around the specimen drawer between the two or more projection images of the tissue specimen.

11. The specimen radiography system of claim 10 , wherein the specimen drawer is moveable between the x-ray source and the x-ray detector for the at least one magnification image of the tissue specimen.

12. A method of imaging a tissue specimen in a specimen radiography system, the method comprising:
supporting the tissue specimen with a specimen drawer of a cabinet;
obtaining two or more projection images of the tissue specimen via an x-ray detector by controlling relative positions between an x-ray source and the specimen drawer;
generating a 3D data set of the tissue specimen from the two or more projection images of the tissue specimen; and
obtaining at least one magnification image of the tissue specimen via the x-ray detector by controlling relative positions between the x-ray source and the specimen drawer, wherein the relative positions between the x-ray source and the specimen drawer are different for the two or more projection images of the tissue specimen than the at least one magnification image of the tissue specimen.

13. The method of claim 12 , wherein the x-ray source and the x-ray detector are aligned along a vertical axis, and wherein obtaining the two or more projection images of the tissue specimen via the x-ray detector includes rotating the specimen drawer around the vertical axis, and obtaining the at least one magnification image of the tissue specimen via the x-ray detector includes moving the specimen drawer along the vertical axis.

14. The method of claim 12 , further comprising extending the specimen drawer from the cabinet.

15. The method of claim 12 , wherein obtaining the two or more projection images of the tissue specimen via the x-ray detector includes rotating the x-ray source in an arc around the specimen drawer.

16. The method of claim 12 , wherein obtaining the two or more projection images of the tissue specimen via the x-ray detector includes tilting the specimen drawer relative to the x-ray source.

17. The method of claim 12 , wherein obtaining the two or more projection images of the tissue specimen via the x-ray detector includes rotating the x-ray source in an arc around the specimen drawer and tilting the specimen drawer relative to the x-ray source.

18. The method of claim 17 , wherein the x-ray source has a larger degree of rotation than the specimen drawer.

19. The method of claim 12 , wherein obtaining the two or more projection images of the tissue specimen via the x-ray detector includes rotating the x-ray source and the x-ray detector around the specimen drawer.

20. The method of claim 19 , wherein obtaining the at least one magnification image of the tissue specimen via the x-ray detector includes moving the specimen drawer between the x-ray source and the x-ray detector.
