摘要：

This paper presents a 3D reconstruction method of coronary arteries from multiple projections, that works efficiently in two steps: first, a 2D processing is performed to obtain and classify the vessels branches on the projections, estimating also the radii. Then, a novel 3D reconstruction step is performed from pair of projections, finding the best intersections between ray bundles corresponding to the same branches to extract the 3D vessel trajectories, that is robust to motion. Topological constraints are included implicitly imposing vessel connectivity and tubular construction. The preliminary results presented here from a digital phantom and from real data, show good accuracy and performance of the method.
