Abstract

Digital radiography has been used loosely to refer to an entire class of X-ray imaging systems, frequently without reference to the image detector used or the image processing functions applied. These systems have in common the acquisition of a two-dimensional projection image in digital format but include a variety of detectors, techniques, and applications. The key attributes of these systems are improvements in detector design and the ability to process the image (in some cases in real time) to greatly improve the capability for image information extraction. Several image processing functions have been developed which include image subtractions, image additions and averaging, contrast enhancement and windowing, point transformations, correction for detector nonlinear response, and others. The ability to process the image rapidly and in digital format has allowed time mode image subtraction to be carried out conveniently as well as permitting contrast enhancement of the subtracted image. Fairly comprehensive reviews of digital radiography can be found in recent publications by Price et al.,(1) Kruger and Riederer,(2) Brody,(3) and Arnold.(4, 5)
