Paper Abstract

Functional neurosurgery such as stereotactic biopsies, interstitial irradiation, chronic depth electrodes, neuro-stimulator or drug injection, requires the implantation of cerebral probes through the labyrinth of arteries and veins. Current methods used to determine the zones free from blood vessels that can be retained as safe passages for the probe to avoid internal cerebral hemorrhages either lack precision or introduce certain limits. This paper presents a newly developed method aimed at facilitating dependable implantation of cerebral probes. It results from an inter-disciplinary research and is based on applying stereophotogrammetric techniques in radiography. An apparatus permitting stereo-vision of a floating line has been developed. It permits to simulate probe implantations. Tests carried out on an actual human cerebral blood vessels network, under severe experimental conditions, indicate that nearly 100% of the probes can be implanted with the help of the device in all directions without risks of hemorrhages.
