electron radiography

radiography /ra·di·og·ra·phy/ (ra″de-og´rah-fe) the making of film records (radiographs) of internal structures of the body by passing x-rays or gamma rays through the body to act on specially sensitized film.radiograph´ic

body section radiography  tomography.

digital radiography  a technique in which x-ray absorption is quantified by assignment of a number to the amount of x-rays reaching the detector; the information is manipulated by a computer to produce an optimal image.

electron radiography  a technique in which a latent electron image is produced on clear plastic by passing x-ray photons through a gas with a high atomic number; this image is then developed into a black-and-white picture.

mucosal relief radiography  radiography of the mucosa of the gastrointestinal tract in a double-contrast examination.

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

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

spot-film radiography  the making of localized instantaneous radiographic exposures during fluoroscopy.

n.

A radiographic imaging process in which the incident x-rays are converted to a latent charge image and developed by a special printing process to eliminate background fog and image noise.

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.
