Angiographic image is the perspective projection of the whole body from a 3D space to a 2D imaging plane, in which X-ray is used. As such, topological vasculature information has been lost. In 2D angiograms, foreshortening and overlapping are commonly observed in tubular-like structures. Hence, an optimum viewing angle should be determined to observe an interesting vessel segment (IVS) or an interesting...
In this paper, a novel method is developed for the 3-D reconstruction of coronary artery trees from two angiographic images. Due to the rotational distortion and unpredictable motion of the imaging chain, the commonly used pinhole camera model cannot obtain desirable reconstruction of the vascular trees. Curvature Scale Space (CSS) approach is used to find correspondence by choosing two similar views...
