Three-dimensional techniques and artificial intelligence in thallium-201 cardiac imaging

AJR Am J Roentgenol. 1989 Jun;152(6):1161-8. doi: 10.2214/ajr.152.6.1161.


Three-dimensional reconstruction techniques including bull's-eye polar-coordinate maps, surface rendering, and surface modeling have been developed that help interpreting physicians assimilate complex 3-D tomographic data. Comparison of patient data with normal files highlights myocardial perfusion abnormalities, thus facilitating their recognition. In addition, AI systems that use heuristically defined rules derived from an expert knowledge base assist inexperienced observers in drawing conclusions regarding scan abnormalities.
