Difiusion tensor imaging provides information about struc- ture and location of white matter tracts within the human brain which is of particular interest for neurosurgery. The reconstruction of neuronal structures from difiusion tensor data is commonly solved by tracking algorithms based on streamline propagation. These approaches gener- ate streamline bundles that approximate the course of neuronal flbers. For medical application, a 3D representation of streamline bundles pro- vides valuable information for pre-operative planning. However, for intra- operative visualization, surfaces wrapping eloquent structures are re- quired for integration into the OR microscope. In order to provide hulls tightly encompassing the neuronal structures obtained from flber track- ing, we propose an approach based on tetrahedralization. This technique reuses the sampling points derived from flber tracking and therefore pro- vides precise hulls which serve as basis for intra-operative visualization. |
