Abstract :
A method for estimating the three-dimensional (3-D) skeletons and transverse areas of the lumens of coronary arteries from digital X-ray angiograms is described. The method is based on the use of a 3-D generalized cylinder. The estimates of the transverse areas are based on a nonlinear least-square-error estimation technique described by Marquardt. This method utilizes densitometric profiles, boundary estimates, and the orientation of the medial axis or skeletons of the arteries in 3-D space. By extending this method to two views, as in biplane angiography, it is possible to obtain the 3-D skeletons and the transverse areas of these lumens. The procedure requires little human intervention
