Abstract
A rule-based expert system for the interpretation of
the 3D myocardial perfusion distributions obtained
from thallium-201 tomographic images has been
developed. This system infers the extent ant severity
of coronary artery disease from the perfusion
distributions, and provides as output a patient
report summarizing the condition of the three major
coronary arteries:
-Left Anterior Descending/
Left Coronary Artery(LAD/LCA)
-Left Circumflex(LCX)
-Right Coronary Artery/
Posterior Descending Artery(RCA/PDA)
Thus automatic decision support is provided to the
physician.
