Surgical Simulation in an Anatomical/Functional Atlas with HyperCAS
Surgical simulation in an anatomical/functional atlas was examined. The atlas of the hypothalamus region, constructed by referencing the standard brain atlas of Schaltenbrand and Wahren, had irregular slice thickness. Newly modified software, “HyperCAS for Neurosurgery,” could work correctly with this irregularity. Simulations of two scenarios of thalamotomy and pallidotomy were performed, and the invasion trajectories of these cases were demonstrated. Simulation on the anatomical/functional atlas could supply detailed information.
