ANATOMICAL PHANTOM CT STUDY OF SURGICAL APPROACHES FOR 3-D AND VR IN NEUROSURGERY

In eight specimens a spiral CT and 3-D reconstruction with post-proces sing at an Allegro work station were done. In all specimens approaches of neurosurgical interest were dissected. For example, a transnasal a nd a transoral approach as computer aspects and real anatomy aspect ar e presented in parallel by photography. The limits of the computer rec onstruction are directly visible by comparison with the real anatomy. Additionally, one endoscopic aspect and one 'virtual reality' aspect a re presented to be compared with real actual anatomy. The problems and possibilities of using 3-D spiral CT developed anatomy are discussed.
