Abstract
We have developed a rule-based, expert system for the analysis of digital angiographic images. The standard method of analyzing the sequence of images from an injection of contrast material ignores the information contained in the time sequence. This results in significant errors in the calculation of percent stenosis -particularly in vessels sloped with respect to the image plane. We have aimed at using the complete time sequence to improve the accuracy of detection and quantification of stenosis in arteries.
