Paper Abstract

Image guided neurosurgery is becoming more widely used as conventional stereotactic techniques are replaced by frameless systems which allow flexible but accurate positioning of surgical approach routes with reduced invasiveness. We have developed a surgical planning and guidance system (VISLAN) which uses stereo video to construct an Intra-Operative Patient Representation (IOPR) and to track a hand-help locator in real time. The IOPR is automatically registered with the Pre-Operative Patient Representation (POPR), which is constructed from MR and other modalities and also includes the surgical plan. Images combining POPR and IOPR objects guide the surgeon on his pre-planned path towards the target.
