Interactive Exploration of Extra- and Intracranial Blood Vessels

Abstract. We present a system for interactive explorations of extraand intracranial blood vessels. Starting with a stack of images from 3D angiography, we use virtual clips to limit the segmentation of the vessel tree to the parts the neuroradiologists are interested in. Furthermore, methods of interactive virtual endoscopy are applied in order to provide an interior view of the blood vessels.
