xeroradiography

 [ze″ro-ra″de-og´rah-fe]
the making of radiographs by a dry, totally photoelectric process, using metal plates coated with a semiconductor such as selenium; the image produced by this process differs from conventional x-ray in that margins between tissues of varying densities are more clearly defined. Hence, xeroradiography is especially beneficial in the diagnosis of breast tumors. It does, however, require higher doses of radiation. Called also xerography.
negative mode xeroradiography a xeroradiographic image that is blue and white but that has been reversed so that white represents the dense areas.
positive mode xeroradiography a xeroradiographic image that is blue and white, with blue representing the dense areas.

xe·ro·ra·di·og·ra·phy

(zē'rō-rā'dē-og'ră-fē),
Radiography using a specially coated charged plate instead of x-ray film, developing with a dry powder rather than liquid chemicals, and transferring the powder image onto paper for a permanent record; edge enhancement is inherent.
Synonym(s): xerography

xerography, (zirog´rəfē),

n a dry radiologic process in which an image is made on a metal plate coated with powdered selenium. The plate is electrically charged in a dark room. Exposure to light or roentgen rays causes the charge to be redistributed in a pattern proportional to the intensity of exposure in various areas of the plate. When “developed” in a cloud of charged particles, the particles are attracted to the areas discharged by radiation, producing the equivalent of a photographic negative.
