Abstract

Based on the VIVENDI-framework for virtual endoscopy, we present a system for the interactive and multi-modal representation of important anatomical structures for neuroendoscopic interventions. A serious problem of neuroendoscopic interventions is the possibility of injuring a blood vessel while performing endoscopic surgery inside the human brain. Besides the sudden loss of optical visibility due to the red-out of the injured vessel, a potential lethal mass bleeding can be the fatal outcome of the intervention. To avoid accidental lesions, we represent the relevant information using multiple volumetric MRI-based representations of the respective organs.
