Abstract

Over the past years, an extensive software package has been developed to determine quantitatively the location, extent and type of thallium-201 myocardial perfusion abnormalities from early and late post-exercise scintigrams. The analysis is based on circumferential profiles obtained from the early and late post-exercise images and a computed washout profile. A prototype of an expert system shell has been built, called ESATS, for the objective interpretation of the scintigraphic studies. Basically, ESATS consists of a knowledge base, a fact base and a control mechanism. The control mechanism features both top-down and bottom-up reasoning and allows external procedures to be called. The development leading towards this rule-based expert system are described.
