Xerography of the breast

Xerography of the breast has many advantages over conventional mammography done with Eastman Kodak “M” Film. There is greater detail on the xerograms, and they are easier to produce and interpret. Xerography utilizes an electrostatic charge placed on a photoconductive surface (a selenium-coated aluminum plate) which is then exposed to radiant energy in the form of x-rays. The residual electrostatic charge is developed by spraying the plate with negatively charged powder. The image is then transferred to paper by pressure for permanence. A better image is produced by xerography with less radiation than is needed with conventional film mammograpy. With further development of the equipment, results of this new technique can be even more encouraging.
