The study of the mass center (CM) motion of the left ventri-cle (LV) area in echocardiographic videos is presented. CM of any phase of the cardiac cycle is inside an ellipse. An area of the ellipse is not more than 2% of the area of LV in systole. The criterion to identify correct and incorrect forms of contours are proposed for automatic contouring of LV(More)
Signatures of medical contouring of the left-ventricular (LV) regions are studied. This research is part of addressing the general problem on automatic contouring of LV regions on ultrasound frames with apical four-chamber cardiac projection. A signature is a curve of an LV contour plotted in polar coordinates. The optimal point in the center of the LV(More)
