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.

(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

xeroradiography

A form of X-ray screening for breast cancer in which the image is formed on special photographic paper instead of on transparent film. Xeroradiographs can be viewed directly without special lighting. Also known as xeromammography.

The basic problem of Xeroradiography method is the requirement of high-dose radiation exposure onto the patients for image making.4
Soft tissue radiography of neck and xeroradiography are not useful predictors of the histology of thyroid nodule, as neither of these investigations are sufficiently sensitive or specific to predict the histologic feature of the nodules.
Soon afterward, Xerographic methods were applied as a substitute for film radiography -- a procedure known as Xeroradiography.[16] Carlson's rights to the process were exploited around 1947 by the Hayloid Corporation, which later became the Xerox Corporation.
