ABSTRACT:
A flat rigid plate having a specialized contoured shape that allows it to best fit the contoured x-ray pattern generated by the different breast tissues on both mediolateral oblique view and craniocaudal view mammogram films. A lower, larger portion of the plate is shaped in the fashion of the lower portion of a spade, with bilaterally symmetrical lobes and a flared stem. An upper, smaller portion of the plate is trapezoidal shaped, having rounded corners. A medical professional examining a mammogram uses the stem as a handle while positioning the plate so that it obscures certain parts of the mammogram. The shape of the plate enables the medical professional to cover any of the film representing the more radiopaque breast tissues that would otherwise present photographic contrast and adversely affect the viewing of a breast tissue area chosen for examination.
