Surface Reconstruction of Coronary Artery Based Coronary Angiograms
Sun Zheng · Journal of Engineering Graphics · 2005
In this paper we propose a new surface reconstruction technique to reconstruct three-dimensional coronary artery from two single plane X-ray angiograms. Local coordinate system of each sampling point is set up after fitting the vessel centerline with B-spline curve. And we present the elliptical model of vessel cross-section and its equation. Then a novel technique of vertex merging is proposed to deal with the problem of self-intersection. The experiments of 3D reconstruction from clinical angiograms validate the method put forward in this paper.
