Paper Abstract

An algorithm is proposed to calculate the left ventricular volume by the number of the filled pixel. Firstly, A closed B-spline curve is used to show the left ventricle's each section outline, then we can fill the left ventricle and a regular three dimension object whose volume is known at the same display mode, finally, the left ventricular volume can be got by the ratio of the two objects' filled pixel numbers. When we fill the left ventricle, three methods are used. They are methods to get the intersect points of a horizontal plane and B-spline curves, to get the extremum point of a B-spline curve, and to fill a closed B-spline curve. Taking results from CMRI as reference, it is showed that the algorithm in this paper is more valid and reliable than that of COMPACT4.2.
