Abstract
In this paper, a method for virtual stenting of carotid stenosis is presented. The method simulates the expansion of a stent inside preoperative computed tomography angiography (CTA) data and allows to predict the wall appearance and the stent shape. Therefore, it supports the selection of a proper stent before an intervention takes place, even in difficult cases. The physical simulation of the forces interacting between stent and vessel wall is based on the Active Contours Method (ACM) in 3D. In contrast to existing stent simulation tools that include wall/stent interaction during the stent expansion, the proposed approach requires less computational effort and less user interaction. Only the start- and endpoint of the stenosis section, the stent position and the stent dimensions have to be defined by the user. Setting up the elastic artery wall and performing the virtual stenting can be achieved automatically in a few seconds for a CT angiography (CTA) dataset of an individual patient. Results of the proposed approach are presented for real CTA data of carotid stenosis.
