This paper presents a semi-automatic coronary centerline extraction algorithm for computed tomography angiography data. The method applies region growing to computed tomography angiography data and incorporates bifurcation and leak detection. The presented method is evaluated either on the original data and on data in which vessel-like structures have been enhanced. Semi-automatically extracted centerlines...
A novel approach for vessel axis tracking is presented based on surface evolution in 3D. The main idea is to guide the evolution by analyzing the topology of intermediate segmentation results, and in particular, to impose shape constraints on the topology. For example, the topology can be constrained to represent a bifurcation, which can be imposed by extracting three different connected paths with...
