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

Some examples are; Xerox, a pioneer in Xerography in the early 60's and today, nearly 50 years later, everyone says, "get me a Xerox copy of this document." Everyone who thinks of the sneaker, the first name that comes to mind is Nike and that is also true in the shaving area, where the first name that comes to mind is Gillette.
"By continuing to focus on xerography breakthroughs and scaling our proprietary inkjet technology, Xerox's advantage to this marketplace is in how we help customers adopt the right technologies, workflow and services to build profitable businesses right now and far into the future," said Chris Govier, General Manager - Production Systems Group Xerox Middle East and Africa.
