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

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.

Trivitron aims to reach 1 billion rupees in core revenue (approximately $15.6 million) within three years of the joint venture's operations by manufacturing X-ray generators, high frequency X-ray machines, mobile and full-room digital radiography. "This joint venture is in line with Trivitron's philosophy of making technology accessible and affordable to a large section of the population," said G.S.K.
Significant, but not insurmountable challenges were introduced during the transition from screen-film to digital radiography, including concerns about poor image quality and unnecessary patient radiation exposure.
