QUANTIFICATION OF MYOCARDIAL CONTRACTILE FUNCTION WITH MRI, CT OR US

摘要

A system (10) for quantification of uncertainty of contours includes a display (48) which displays a portion of a 4D image of at least a left ventricle over a plurality of cardiac phases. A measurement device (16) includes at least one processor (42) programmed to receive the 4D image (18) from an imaging device (12), receive a selected location on the myocardial wall of the left ventricle, cast a ray perpendicular to at least one of the myocardial wall or center of the left ventricle through the selected location, calculate a thickness the myocardial wall along the cast ray, evaluate myocardial wall motion over the range of the cardiac phases, calculate a quantification of the myocardial contractile function, and display the calculate a quantification of the myocardial contractile function on the display device (48).
