Abstract

A vascular tracing technique is described using a digital storage method which optimizes the contrast produced from radiographic images using very small quantities of contrast medium. The effects of further post processing and the production of high quality hard copy in a multiformat camera are illustrated with a number of clinical examples. The implications of this technique are discussed, including the possibility of producing clinically acceptable digital angiographic images at relatively low cost. The effect of digital averaging on fluoroscopy dose reduction is also illustrated.
