The author has performed a subjective comparison of breast images recorded with a new liquid-toner xerographic system and images of the same breasts recorded on Kodak OM-1 film exposed with a MinR screen and a 5 to 1 grid. The xeromammograms are judged to be superior to the mammograms recorded on film with respect to: (1) the demonstration of calcifications, circumscribed masses, and the back of the breast; (2) the "resolution" of dense connective tissue; and (3) the overall image quality. Radiation doses to the breast associated with the two types of study are said to be comparable. Thirteen pairs of excellent images comparing xeromammograms with conventional breast films are presented.
作者对使用新型液体调色剂静电复印系统记录的乳房图像与用MinR增感屏和5比1滤线栅曝光、记录在柯达OM-1胶片上的同一乳房图像进行了主观比较。就以下方面而言，干板乳房X线照片被判定优于胶片记录的乳房X线照片：（1）钙化、边界清晰的肿块以及乳房后部的显示；（2）致密结缔组织的“分辨率”；（3）整体图像质量。据说，与这两种研究相关的乳房辐射剂量相当。文中展示了13组比较干板乳房X线照片与传统乳房X线胶片的优质图像。
