Abstract
A method of left ventricular volume evaluation capable of obtaining an accurate evaluation of the left ventricular volume for a heart in an unaffected state. In the method, right anterior oblique image and 4-chamber image of the heart are obtained; using a nuclear magnetic resonance imaging, contours of the left ventricle in the right anterior oblique image and the 4-chamber image are determined; prescribed sets of sizes for the left ventricle are measured from the determined contours; and the volume of the left ventricle is evaluated by using an orthogonal biplane Simpson's method and the measured sizes.
