Development of fitting model for visualization of left ventricle in gated SPECT image using least squares method

Cardiac disorder is one of the important diseases. Three-dimensional visualization and motility analysis of heart are necessaries to diagnosis of cardiac disorder. Because it is an important that diagnosis of cardiac disorder considers changing of shape with the passage of time. The purpose of this paper is to create a standard model of left ventricle myocardium. We restored the lost apex of heart in the process of image acquisition and interpolated. We found an algorithm for it using the least squares method. Furthermore we added some conditions the passed the points in the general least square method. It is an important point to determine the shape of left ventricle myocardium. We expect that the proposed algorithm should be helpful for a development of standard model.
