Automatic left ventricular outlining.
A method for automatically outlining the left ventricle is described. The boundary at any point in the heart cycle is obtained from a convoluted image derived from an ordinary frame of count rate convoluted with a functional image frame scaled in the time of maximum count rate. The position of the pulmonary artery indicates the level of the aortic valve plane.
