Abstract :
In this paper, we introduce an approach for selective segmentation of vascular structure which has been applied for intracranial vessels. Based on MIP and fuzzy set principles, this approach brings good results while segmentation is achieved rapidly. The added value of this approach is a minimal user interaction and the taking into account of the volume partial effect. This approach has been evaluated following different experiment: phantom tests, clinical data, and methods comparison.
