Video clip showing the dynamic segmentation of the left ventricle. [MPEG2 video: addfile1.mpg] (left) preprocessed image with atrioventricular barrier; (center) watershed segmentation; (right) estimated contour. Note the automatic positioning of the atrioventricular barrier, which dynamically tracks the mitral valve. This 2D-echo sequence was classified as of average image quality by a specialist.
