Abstract
This paper deals with a method of three dimensional reconstruction of coronary arteries by mapping CAGs on myocardial nuclear image.The bi-plane CAG images are mapped onto LV surface modelwhich is pre-determined on nuclear 3D image.By maximizing a matching degree between two mapped CAG images,registration between CAGs and nuclear myocardial image is performed automatically. By taking only true images from the mapped CAG images, we can obtain 3D reconstructed coronary image. This method has the great advantage thatit's not necessary to identify the correspondence of feature points.The obtained images give us clear understanding of the relation between anatomy of coronary artery and function of the myocardium.
