Abstract
Multi-slice computed tomography (MSCT) has developed strongly in the emerging field of cardiovascular imaging. The manual analysis of atherosclerotic plaques in coronary arteries is a very time consuming and labor intensive process and today only qualitative analysis is possible. In this paper we present a new shape-based segmentation and visualization technique for quantitative analysis of atherosclerotic plaques in coronary artery disease. The new technique takes into account several aspects of the vascular anatomy. It uses two surface representations, one for the contrast filled vessel lumen and also one for the vascular wall. The deviation between these two surfaces is defined as plaque volume. These surface representations can be edited by the user manually. With this kind of representation it is possible to calculate sub plaque volumes (such as: lipid rich core, fibrous tissue, calcified tissue) inside this suspicious area. Also a high quality 3D visualization, using Open Inventor is possible.
