Device for cushioning of compression surfaces
According to the present invention, improved methods and apparatus are provided for providing cushioning and other ergonomic surfaces on devices requiring the patient or tissue to be compressed, such as radiography machines, fluoroscopy units, mammography units and the like. In particular a radiolucent pad element is provided for releasable attachment to at least one surface of a compression device to be used under x-ray, for example, during mammography. The pad element of the present invention can be disposable or constructed to be reusable and in some cases may be applied directly to the patient's breast. Furthermore, a cushioned paddle is provided wherein the compression paddle and the cushion can be separately or integrally formed.
1. A device for attachment to a compression surface of a compression device of an imaging unit, said device for attachment comprising:
a radiolucent comfort device shaped to cover the compression surface of the compression device and having a first surface and a second surface, the comfort device comprising material producing no significant visual artifact on an x-ray image while in use and providing a less harsh or cold surface; and
means for releasably attaching the first surface of the comfort device to the compression surface.
2. A device for attachment to a compression surface of a compression device of an imaging unit, said device for attachment comprising:
a radiolucent comfort device having a first surface and a second surface, the comfort device comprising material producing no significant visual artifact on an x-ray image while in use and providing a less harsh or cold surface; and
means for releasably attaching the first surface of the comfort device to the compression surface, wherein the means for releasably attaching comprises an adhesive layer on at least the first surface of the comfort device.
3. The device of claim 2 , wherein the adhesive layer covers the entire first surface.
4. The device of claim 2 , wherein the adhesive layer covers only certain regions of the first surface.
5. The device of claim 4 , further comprising wherein the adhesive layer extends along a border of the first surface.
6. The device of claim 1 , wherein the comfort device comprises polyurethane.
7. The device of claim 1 , wherein the comfort device has a thickness between 0.050 inch and 0.500 inch.
8. The device of claim 1 , wherein the compression device comprises a front surface, and wherein the comfort device is foldable to releasably attach the comfort device to the compression surface and the front surface of the compression device.
9. A device for attachment to a compression surface of a compression device of an imaging unit, said device for attachment comprising:
a radiolucent comfort device having a first surface and a second surface, the comfort device comprising material producing no significant visual artifact on an x-ray image while in use and providing a less harsh or cold surface; and
means for releasably attaching the first surface of the comfort device to the compression surface,
wherein the comfort device comprises foam.
10. A method for imaging a breast using an upright imaging device comprising an x-ray source and first and second compression plates, the method comprising:
providing a radiolucent comfort device on a compression surface of the first compression plate in an imaging field of the x-ray source;
compressing a breast between the first and second compression plates, the comfort device providing a less harsh or cold surface during compression; and
obtaining an x-ray image of the compressed breast, the comfort device producing no significant visual artifact on the x-ray image.
11. The method of claim 10 , further comprising removing the comfort device from the first compression plate after obtaining the x-ray image.
12. The method of claim 10 , wherein providing a comfort device comprises releasably attaching the comfort device to the compression surface of the first compression plate.
13. The method of claim 10 , wherein the first compression plate comprises a front surface outside the imaging field, and wherein the comfort device extends onto the front surface.
14. The method of claim 10 , wherein the comfort device reduces patient movement during compression of the breast.
15. The method of claim 10 , wherein the comfort device reduces motion artifact on the image.
16. The method of claim 10 , wherein the imaging device comprises one of a radiography machine, a fluoroscopy unit, and a mammography unit.
17. A device for attachment to a compression surface of a compression device of an imaging unit, comprising:
a radiolucent comfort device having a first surface and a second surface, the comfort device comprising material producing no significant visual artifact on an x-ray image while in use and providing a less harsh or cold surface; and
an adhesive on the first surface of the comfort device to attach the comfort device to the compression surface.
18. The device of claim 17 , wherein the adhesive layer covers the entire first surface.
19. The device of claim 17 , wherein the adhesive layer covers only certain regions of the first surface.
20. The device of claim 17 , wherein the comfort device has a thickness between 0.050 inch and 0.500 inch.
