Paper Abstract

Details of a method of determining the center and radius of an apacified vessel, such as an artery, from its x-ray projection are given. These parameters are determined to a typical accuracy of better than 0.1 pixel in the absence of noise. The effects of both gaussian noise and digitization interval are determined, as well as the effect of pixel size/vessel diameter. A method of finding x-ray system parameters is presented, and the algorithm for center and radius determination is confirmed from measurements on a DSA shadowgraph of a opacified tube.
