ABSTRACT:
Disclosed is a breast compression assembly for an mammography apparatus and a breast compression plate for use in such apparatus. The assembly includes a first compression plate having a first compression surface extending from an input edge thereof and a second compression plate having a second compression surface extending from an input edge thereof. At least one of the compression plates includes an associated ridge member affixed to its input edge. The ridge member extends beyond the surface of the associated compression plate in the direction substantially perpendicular to the compression surface of the plate. The device further includes means for positioning the first and second compression plates, and means for selectively controlling the separation between the compression surfaces of the plates along a reference axis substantially perpendicular to the compression surfaces of the plates.
