Abstract
A method is provided for automatically determining quantitative characteristics of organ images, especially echocardiographic images. A diagnostic image is obtained and then a center point for the approximately curvilinear bounded organ is determined by repeatedly filtering the image with a set of circular arc filters until a maximum value for the filter set is obtained, whereupon parameters of cardiac wall motion, wall thickness and area change fraction may be determined to detect ischemic or other organ abnormality.
