ABSTRACT:
A compression apparatus for use with conventional mammography apparatus is disclosed. The apparatus comprises a frame which may be attached to a conventional mammography device's compression paddle carriage. The apparatus further comprises a compression surface having a chest wall end and a nipple end, pivotally attached to the frame at a pivot point located between the chest wall end and the nipple end. To provide adequate compressive forces at the chest wall end of the compression surface while allowing rotation about the pivot point, a spring is attached between the frame and the compression surface at the nipple end of the compression surface.
