dig·i·tal ra·di·og·ra·phy (DR),

direct conversion of transmitted x-rays into a digital image using an array of solid-state detectors such as amorphous selenium or silicon, with computer processing and display of the image. See: digital subtraction angiography.

digital radiography (DR)

[dij′itəl]
any method of radiographic image formation that uses a computer to store and manipulate data. See also digital angiography, digital fluoroscopy, digital tomosynthesis.

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 with12 the amount of radiation, and the images are easier to store, copy and send, as they are digital ab initio

dig·i·tal ra·di·og·ra·phy

(dij'i-tăl rā'dē-og'ră-fē)
Computed radiography or computer processing of a digitized image from a conventional image-intensifier and video camera.

digital radiography

A method of acquisition of an X-ray image in a form that can be stored as a computer file and reproduced as required. A phosphorescent plate is exposed in a standard X-ray cassette and the latent image on it is then scanned with a laser beam to produce a succession of light pulses that are picked up by a photomultiplier tube to produce a bit-mapped image file. This can be printed or displayed on a monitor. The phosphorescent plate can be exposed to light and reused an indefinite number of times. Images are available almost immediately and can be processed to improve contrast and detail. Reduced X-ray dosage to patients and economy in storage are further advantages.

dig·i·tal ra·di·og·ra·phy

(DR) (dij'i-tăl rā'dē-og'ră-fē)
A filmless imaging system wherein a radiographic image is captured using nonfilm, solid-state detectors. The signal so captured is sent to a computer where it is digitized so the image may be displayed in multiple gray levels on a monitor.
