An accurate coronary modeling procedure using 2D calibrated projections based on extracted 3D vessel centerlines

Abstract

This paper describes a method for the three-dimensional (3D) reconstruction of coronary arterial segments from three projection boundaries. The method is based on the 3D generalized cylinder (GC) model with elliptic cross-sections and mainly consists of a model-based estimation of the vessel boundaries, precise computation of the ellipse parameters of arterial cross-sections from the estimated boundaries, and obtaining the 3D structures by linking consecutive cross-sections. Synthetic and real experiments showed that the method is robust to degradation sources and consequently superior to the two-view method because it uses boundary instead of gray-level information.
