Abstract
XERORADIOGRAPHY is a new medium for recording roentgen images. Unlike conventional film, it uses no solution of any sort and thereby derives its name from the Greek word "xeros," meaning dry. It is photoelectric in nature rather than photochemical. The basic element in the process is a metallic plate coated with a thin layer of selenium, a semiconductor. In practice, a homogeneous electric charge is sprayed on the surface of the selenium. The plate is then exposed to x-rays in the same fashion and with the same equipment one would utilize if ordinary x-ray film were to be employed. The x-rays which pass through the subject and strike the plate selectively dissipate the electric charge on the selenium. This results in the production of a latent electrostatic image. The image can be made visible by dusting the surface of the selenium with finely divided powder granules which adhere to the
