1. In a mammography system for patients with breast implants, apparatus for compressing and positioning the breast for penetrating radiation and image formation of internal tissue on X-ray film, the improvement comprising:
- a compression paddle means formed of transparent, X-ray transmissive material which is substantially rectangular in shape with extended front corners, the paddle means including a planar bottom having sidewalls extending normally from the bottom surrounding the periphery thereof, an arcuate cutout means in the front edge of the planar bottom shaped to substantially surround while not compressing the breast implant, the front corners of the paddle extending outward from the arcuate cutout so that tissue laterally of the implant can be examined at the same time.

Abstract
The present invention provides a mammographic compression technique which permits the paddle to be aligned in any angular view with the cutout portion of the paddle positioned over the implant to reduce the amount of compression of the implant thereby lessening the blockage of the breast tissue. The invention comprises a compression paddle formed of x-ray transmissive material having sidewalls extending normally from a planar bottom surrounding the periphery which lays outside of the cutout portion.

5. A mammography system for patients with breast implants, apparatus for compressing and positioning the breast for penetrating radiation and image formation of internal tissue on X-ray film, comprising:
-
a base member; a radiation source emitting a beam; a stationary compression member containing a removable film plate connected to the base member; a linear transport means on the base member; a compression paddle means attached to the transport means acting in conjunction with the stationary compression member, the paddle means formed of a transparent X-ray transmissive sheet which is substantially rectangular in shape with extended front corners, the paddle means includes a planar bottom having sidewalls extending normally from the bottom surrounding the periphery thereof, an arcuate cutout means in the front edge of the planar bottom shaped to substantially surround while not compressing the breast implant, the front corners of the paddle means extending substantially outward from the cutout so that tissue laterally of the implant can be examined at the same time. - View Dependent Claims (6)
