digital 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.

digital radiography

Imaging A format for producing x-rays in which film used to produce conventional x-ray images is replaced with more sensitive sensitive electronics; DXRs produce images with¹⁄₂ the amount of radiation, and the images are easier to store, copy and send, as they are digital ab initio
