Abstract

A system and method using an inflatable jacket over the compression paddle of a mammography and/or tomosynthesis system to enhance imaging and improve patient comfort in x-ray breast imaging.

First claim

The invention claimed is:

1. An x-ray breast imaging system comprising:
a breast immobilizer comprising a breast platform configured to support a patient's breast for imaging and a compression paddle supported for movement toward the breast platform to compress the breast and away from the breast platform to release the breast;
said compression paddle having a front wall configured to be adjacent the patient's chest wall when the patient's breast is supported for said imaging, side walls extending transversely to the front wall, and an underside facing the breast platform;
a paddle jacket removably secured to the compression paddle, said jacket having a top wall extending along the underside of the paddle when secured to the paddle, and a bottom wall disposed opposite the top wall from the underside of the paddle, wherein the top wall and the bottom wall define an inflatable chamber therebetween, and a fluid conduit that is in fluid flow communication with said chamber, wherein the top wall and the bottom wall are fused to each other so as to form:
side walls that extend along the side walls of the compression paddle, and
a front wall that extends along the front wall of the compression paddle; and

a fluid control unit releasably coupled with said conduit to selectively supply fluid to said chamber through said conduit and thereby selectively inflate the chamber.

2. The breast imaging system of claim 1 in which one or more of the front and side walls of said jacket further comprise clipping members configured to releasably clip upper portions of one or more of the front and side walls of said compression paddle, respectively.

3. The breast imaging system of claim 1 in which one or more of the bottom and front and side walls of said jacket include adhesive material for releasably adhering to said compression paddle.

4. The breast imaging system of claim 1 in which at least the bottom of said jacket is substantially transparent to visible light, whereby a technician adjusting a patient's breast for imaging can visualize the breast through said.

5. The breast imaging system of claim 1 in which said jacket includes markings of a material that attenuate an x-ray beam emitted from an x-ray source sufficiently to be visible in x-ray images.

6. The breast imaging system of claim 1 in which said chamber in divided into two or more sub-chambers that are individually inflatable.

7. The breast imaging system of claim 1 wherein the front wall and the side walls of the jacket are not inflatable.

8. The breast imaging system of claim 1 in which said front wall of said jacket is shorter vertically than the front wall of the compression paddle.

9. An inflatable compression paddle jacket configured to be releasably secured to a compression paddle configured to compresses a patient's breast for x-ray imaging, said paddle having an underside, a front wall and left and right side walls, said jacket comprising:
a bottom comprising one or more inflatable chambers, said bottom having an upper surface configured to face the underside of said compression paddle when the jacket is secured to the paddle, wherein when the one or more chambers are inflated, the bottom comprises a first thickness;
one or more of a front wall, a left side wall and a right side wall configured to face one or more of the respective wall of the compression paddle when the jacket is secured to the paddle, wherein each of the front wall, the left wide wall, and the right side wall comprise a second thickness less than the first thickness; and
a conduit connecting an interior of the one or more of the inflatable chambers for fluid flow from an exterior thereof for selectively inflating the one or more chambers of the jacket.

10. The inflatable jacket of claim 9 in which said jacket bottom comprises two layers of flexible material that are seamed at selected portions thereof to form said one or more inflatable chambers.

11. The inflatable jacket of claim 10 in which said layers are seamed at one or more seams that extend at least along a lower portion of the front wall of said compression paddle when the jacket is secured to the paddle for x-ray imaging of the patient's breast.

12. The inflatable jacket of claim 10 in which said layers are seamed at one or more seams that extend at least along a front portion of the underside of said paddle when the jacket is secured to the paddle for x-ray imaging of the patient's breast.

13. The inflatable jacket of claim 10 in which said layers are seamed at one or more seams that extend at least along a junction of the front wall and the underside of said paddle when the jacket is secured to the paddle for x-ray imaging of the patient's breast.

14. The inflatable jacket of claim 10 including one or more clipping portions at the one or more of the walls of the jacket, said clipping portions configured to engage one or more of the respective walls of the compression paddle when the jacket is secured to the paddle for x-ray imaging of the patient's breast.
