The vascular territory commonly characterizes clinically ischemic heart disease. We describe an automated and quantitative approach for the evaluation of discrete myocardial wall motion in terms of vascular territory (i.e. LAD, RCA, and LCX), using a novel wall motion characterization method called regional center point trajectory algorithm. The three-segment center point model enables separate analysis and quantification of coronary artery disease by their respective vascular territories, thereby allowing segmental tracking and quantification of wall motion.
