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 cabinet comprising:
an x-ray source defining a focal point;
an x-ray detector defining an image plane, wherein the x-ray source and the x-ray detector are aligned relative to one another about a vertical axis;
a specimen drawer configured to support a tissue specimen; and
a door allowing access through an opening of the cabinet for the specimen drawer, wherein the specimen drawer is at least partially movable through the opening when the door is open, and wherein the specimen drawer is selectively positionable along the vertical axis within the cabinet and between the focal point and the image plane; and
a controller operably coupled to the x-ray source and the x-ray detector and configured to image the tissue specimen, wherein a position of the specimen drawer along the vertical axis defines a magnification of an image of the tissue specimen.

2. The specimen radiography system of claim 1 , wherein the x-ray source is positioned above the x-ray detector in the cabinet.

3. The specimen radiography system of claim 1 , wherein the controller is operably coupled to the specimen drawer such that the position of the specimen drawer along the vertical axis is at least partially automatically controlled.

4. The specimen radiography system of claim 1 , wherein a central vertical axis of the specimen drawer is aligned with the focal point of the x-ray source.

5. The specimen radiography system of claim 1 , wherein the position of the specimen drawer along the vertical axis is pre-defined.

6. The specimen radiography system of claim 1 , wherein the cabinet further includes wheels.

7. The specimen radiography system of claim 1 , further comprising a display and a user interface, both operably coupled to the controller.

8. The specimen radiography system of claim 7 , wherein the display and the user interface are supported on the cabinet.

9. The specimen radiography system of claim 1 , wherein the controller automatically controls a movement of the specimen drawer through the opening of the cabinet.

10. The specimen radiography system of claim 1 , wherein a movement of the specimen drawer through the opening of the cabinet is orthogonal to the vertical axis.

11. 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;
moving the specimen drawer through an opening of the cabinet when a door is open such that the tissue specimen is received within the cabinet;
positioning the specimen drawer relative to a vertical axis defined between a focal point of an x-ray source and an image plane of an x-ray detector;
imaging the tissue specimen, using a controller operably coupled to the x-ray source and the x-ray detector, wherein a position of the specimen drawer along the vertical axis defines a magnification of an image of the tissue specimen; and
displaying the image of the tissue specimen on a display operably coupled to the controller.

12. The method of claim 11 , wherein the step of moving the specimen drawer through the opening of the cabinet occurs prior to the step of positioning the specimen drawer relative to the vertical axis.

13. The method of claim 11 , wherein imaging the tissue specimen includes positioning the x-ray source above the x-ray detector in the cabinet.

14. The method of claim 11 , further comprising controlling, by the controller operably coupled to the specimen drawer, a position of the specimen drawer along the vertical axis.

15. The method of claim 11 , further comprising controlling, by the controller operably coupled to the specimen drawer, a movement of the specimen drawer through the opening of the cabinet.

16. The method of claim 15 , wherein the movement of the specimen drawer through the opening of the cabinet is orthogonal to the vertical axis.

17. The method of claim 11 , wherein moving the specimen drawer through the opening of the cabinet includes aligning a central vertical axis of the specimen drawer with the focal point of the x-ray source.

18. The method of claim 11 , wherein the position of the specimen drawer along the vertical axis is pre-defined.

19. The method of claim 11 , wherein the cabinet is supported on wheels, and wherein the method further comprises moving the cabinet in position for imaging.

20. The method of claim 11 , wherein the display is supported on the cabinet, and wherein displaying the image on the display occurs on the cabinet.
