ABSTRACT:
An overlay device enabling evaluation of a mammography film image and a method thereof wherein a transparent overlay, graphically marked with a two-dimensional scaled grid coordinate system, is placed over and aligned with either a mediolateral oblique or craniocaudal mammography film image, thereby enabling specific and reproducible evaluation of a mammography film image by assisting in positioning evaluation by providing the identification of all structures in two planes, enabling training guidance by providing AEC centerline for symmetry evaluation, and enabling image evaluation by providing AEC sensor positions markings specific for each manufacturer's system; thus, allowing complete evaluation of positioning and imaging technique.
