3D reconstruction of coronary arteries from rotational X-ray angiography

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...
