Abstract: An improved mammographic apparatus for patients having prosthetically augmented breasts. The apparatus has an X-ray source with an upper breast compression and lower compression plate mounted in one X-ray path. The anterior surface of the compression plates adjacent the patient are curved and sloped conforming to the patient's anatomy to avoid trapping the prosthetic envelope of patients during compression of the breast. In one embodiment, the wall surface of the compression plates adjacent the patient are pliable to allow medical personnel to conform the walls of the plates to the anatomy of the patient. The film holder associated with the lower compression plate may be modified so it may be loaded from below the lower compression plate or from the rear to accept a specially shaped film cassette.
