Abstract
The use of digital imaging techniques for state projection radiography is, at present, in a clinical evaluation phase (Stein 1976; Fräser et al. 1983; Tesic et al. 1983; Sonada et al. 1983). Further refinements in system architecture are possible, but have not yet been developed or tested in the laboratory or clinic. On the other hand, digital techniques for vascular imaging, using a digitized video signal, are well established and digital subtraction angiography (DSA) is now accepted as an integral component of a state-of-the-art angiographic system (Kruger and Reiderer 1984). DSA systems are characterized by rapid frame rate, enhanced on-line subtraction and instantaneous review on a television monitor. Post-processing techniques designed to improve anatomical registration and image quality as well as to remove motion artefacts have been developed and implemented (Foley et al. 1983).
