The coronary arterial 3-D reconstruction is playing an important role in grasping their structures of anatomy and providing quantitative information such as flow or stenosis measurements. This paper describes a new method to reconstruct 3-D coronary arterial branches from 2 plane X-ray angiograms. The key point of the method is estimating the 3-D coordinates necessary for reconstruction through the information extracted from the original angiograms and easily notable parameters ; the geometric parameters of the X-ray system and the mutual position between the patient and the X-ray system. It is not necessary to take images of a phantom as the standard for the measurement of the shape and the position. Thus this method gives easy 3-D reconstruction process in clinical medicine. Some 3-D results applied to the actual angiograms are shown. Moreover for easy understanding of the structure, 3-D image fusion is introducted; 3-D left ventricle with the aorta reconstructed through the usual left ventriculograms and 3-D coronary artery reconstructed through the coronary angiograms.
