The automatic operation identification of the longitudinal axis of the left cardiac ventricle from the SPECT data by the nuclear medicine which is used for the injection inspection to the myocardium

摘要

(57) Abstract The longitudinal axis of the left cardiac ventricle is identified automatically local smallest strength and maximum strength inside the slice image of the left cardiac ventricle only the identification by correlating. First the left cardiac ventricle is identified while representation intersection slicing of the left cardiac ventricle. It is used the calculate being done, it directs the center line of this slice and as the axis, it forms) the slice of another (sagittal shape direction of the left cardiac ventricle alongside that axis. The center line of slice of this sagittal shape direction is done, the calculate becomes the longitudinal axis of the left cardiac ventricle. Precision of this identification forms the diagonal intersection slice of the left cardiac ventricle, is verified by verifying that those centers agree.
