radiography

[ra″de-og´rah-fe]

the making of film records (radiographs) of internal structures of the body by exposure of film specially sensitized to x-rays or gamma rays. adj., adj radiograph´ic.

body section radiography tomography.

double-contrast radiography mucosal relief radiography.

electron radiography radiography consisting of electronic images that can be computer enhanced, electronically reversed, stored, retrieved, transmitted, and/or printed on photographic film.

mass radiography examination by x-rays of the general population or of large groups of the population.

mucosal relief radiography a technique for revealing any abnormality of the intestinal mucosa, involving injection and evacuation of a barium enema, followed by inflation of the intestine with air under light pressure. The light coating of barium on the inflated intestine in the radiograph reveals clearly even small abnormalities; double-contrast r.

neutron radiography that in which a narrow beam of neutrons from a nuclear reactor is passed through tissues; especially useful in visualizing bony tissue.

panoramic radiography pantomography.

serial radiography the making of several exposures of a particular area at arbitrary intervals.

spot-film radiography the making of localized instantaneous radiographic exposures; see also spot film.

e·lec·tron ra·di·og·ra·phy

radiographic imaging in which x-radiation incident on the receptor is converted to a latent charge image and subsequently recovered by a special printing process; advantages include wider latitude of exposure and greater sensitivity than conventional film-screen combinations. See: xeroradiography, phosphor plate.

Radiographic imaging in which x-radiation is converted to a latent image and subsequently recovered by a printing process.
