A quantitative method, Central Point Trajectory (CPT), of assessing myocardial wall motion is evaluated in this paper. This center point trajectory method is compared and validated against echocardiography systolic peak strain maps and myocardial delayed enhancement images, which shows strong correlation in terms of detection of abnormal regions with reduced wall motion.
