A New Method of Estimating Coronary Artery Diameter Using Direction Codes in Angiographic Images

摘要

The conventional method requires a centerline of a vessel to estimate the vessel diameter. Two mehtods of es- timating the centerline of vessels have been reported: One is to manualy define the centerline of the vessel. This potentially contributes to inter-and intra-observer variability. The orienta- tion of the centerline has an effect on the diameter function since diameters are computed perpendicular to the centerline. And the other is to automatically detect the centerline of the vessel. But this is a very complicated method.
