Abstract

In clinical medicine, the shape and dimensions, especially their dynamical changes, of the human left ventricle have proven to be the most important parameters for evaluating the cardiac functions, and, if they are obtainable, it will be possible to diagnose several cardiac diseases accurately. Currently, heart images are obtained mainly by x-ray cine-angiocardiography or RI-angiocardiography, and techniques such as manual contour tracing and hand planimetry are used by cardiologists to measure the dimensions of the left ventricle. However, because the effort involved in manual methods is fairly great, computerized measurement techniques are urgently desired.
