NEURONAVIGATION - COMPUTER-ASSISTED NEURO SURGERY

Computers in Neurosurgery were limited to diagnostics, planning stereo tactic procedures, Radiosurgery and Radiation therapy. The possibility of intra-operative localisation only evolved since the mid 80's with the advent of more powerful computers. The computer adds more precissi on to microneurosurgical procedures, allowing neuronavigation in inter action with the computer. Diverse neuronavigationsystems are described in the literature [7-9, 11, 13]. we are working with the ''ISG Viewin g Wand'' since april 1994. 113 operations were planed and executed aid ed by this system. We report on our experiences, the advantages and li mitations of this system.
