Superimposed display of the coronary artery on bull's eye map of myocardial SPECT

摘要

This paper deals with a method of superimposing a coronary arterial tree oil a myocardial SPECT image. We can grasp the myocardial function more easily in Connection with the shape of the corollary artery. First, a rough shape of the left ventricle (LV) is estimated by using SPECT data. This 3-D LV model is projected oil a pair of bi-plane CAG images. By scanning the LV surface projected on CAG, we can obtain 2-D coronary images on a bull's eye map of SPECT. By maximizing a matching degree, registration between CAG mid SPECT is performed automatically. Our method has been successfully applied to one artificial data set and several clinical cases.
