Translations

Xeroradiography

xeroradiography

[¦zi·rō‚rād·ē′äg·rə·fē] (graphic arts) An electrostatic image-forming process in which x-rays or gamma rays form an electrostatic image on a photoconductive insulating medium; the charged image areas attract and hold a fine powder called a toner, and then the powder image is transferred to paper and fused there by heat.

Xeroradiography

a method of obtaining X-ray images using semiconductor photographic plates, with the image appearing on ordinary paper rather than on X-ray film.

Developed by the American physicist C. Carlsson in 1938, xeroradiography came into use in the 1960’s as a nondestructive means of checking the parts used in machine building, uranium samples, and the like. It is also used in medicine to diagnose diseases of the bones and milk ducts. It was used for the first time in the USSR in 1964–65 to diagnose diseases of the internal organs and urinary tract. Several new methods of examination originated from it, for example, electroroentgenangiography and roentgenoscanning.

In xeroradiography the exposure (on selenium plates) is done using an X-ray machine, and the latent electrostatic image is developed by dusting with colored powder. The image is transferred from the plate to a sheet of paper and fixed in a special xeroradiographic device. The diagnostic capability of xeroradiography, the speed and convenience in obtaining the photograph (no need for a photographic laboratory or a source of water supply), and its cost effectiveness have made it a promising method of modern X-ray diagnosis, chiefly in traumatology and emergency diagnosis.

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

(zēr'ō-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. Also called 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.
