A Bottleneck Model of Imaging Systems for Digital Angiocardiography

subject

description

Some ten years ago, the performance of real-time digital subtraction angiocardiography was demonstrated for the first time [1]. Subtraction became in the years after 1980 nearly synonymous with digital angiography [2–4]. This image enhancement technique was certainly very efficient in paving the way for the digital approach to imaging. Relatively simple processors and memory structures could perform subtraction methods with some degree of success. However, even in that early stage, it was clear to many of those involved in the technical developments and in early clinical evaluations that subtraction was only one of many features that would motivate the change from traditional film techniques to digital techniques of angiographic imaging so that digital angiocardiography could become the standard procedure in a large part of the angiocardiographic laboratories [5].
