Computed radiography (CR) is a general-purpose diagnostic system developed for application to various kinds of radiography by means of unique imaging plates. We have so far used this system for angiography, taking advantage of one of the features of CR, namely that it allows easy subtracton because it performs analog to digital conversion in the course of processing [1, 2]. Another type of digital angiography is digital fluorography (DF) using an imaging intensifier (II). Since the DF system was originally developed for angiography, there are naturally fundamental differences between the two systems. In routine angiography, however, the two systems have already been widely used, currently for the same purposes in most cases. This chapter includes a comparison of the two systems.
