digital radiography

digital radiography
an alternative to film radiography, by acquiring X-ray images from a large number of individual X-ray detectors on a matrix in a digital format directly. This contrasts with computerized radiography, in which an analogue image is taken and then put into a reader to be converted into a digital image. The technique allows the storage of images on hard disk or digital tape and their subsequent retrieval, manipulation, and interpretation using TV monitors rather than photographic film (see PACS). Digital detectors are currently expensive but are likely to become the preferred technology.

* * *

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