The accuracy of the results depends on reliable cardiac contour determination, which is time consuming and error probe. Normally, clinicians define cardiac contours in the end diastole and the end systole, linearly estimating cardiac parameters such as stroke volume, ejection fraction, etc. We present a method, which propagates a pre-defined cardiac contour through the cardiac cycle. This produces non-linear data, allowing new cardiac studies, for example, the studies of ejection rate and filling rate. </ABSTRACT></RECORD></RECORDS></XML>
