Xeroradiographs

Xeroradiographs, a technology commercially known as mammography, were done at the Xerox Medical Research Center in Pasadena, California, between 1978 and 1982. I placed objects on a charged selenium plate and then put the plate in an X-Ray box, closed the door, and exposed it to X-Ray. The X-Rays changed the charge on the plate wherever they hit the plate. I then placed the plate with a ‘latent image’ into a Xerox machine. The charge on the plate attracted toner with the opposite charge. About a minute later a print emerged. The color blue was chosen because doctors like the color blue. The enclosed prints are digital reproductions of those images, printed on an Epson inkjet printer using archival paper and inks.
