Paper Abstract

During a typical image-guided neurosurgery procedure, the surgeon used anatomical information from tomographic image sets to help guide the surgery. These images provide high- level details of the patient's anatomy. The images do not, however, provide the surgeon with information regarding brain function. The identification of cortical function in addition to the display of tomographic images during surgery would allow the surgeon to visualize critical areas of the anatomy. This would be beneficial during surgical planning and procedures by identifying eloquent cortical regions (such as speech, sensory, and motor areas) that should be avoided. We have designed and implemented a system for recording and displaying cortical brain function during image-guided surgery. Brain function is determined using an optically tracked cortical stimulator. The image-space location of each stimulation event is recorded, and the user has the ability to label this location according to function type. Functional data can be displayed on both tomographic and rendered images. Tracking accuracy of the cortical stimulator has been determined by comparing its position to that of a tracked surgical probe with known localizing accuracy.
