IMAGE DISPLAY AND SURGICAL VISUALIZATION IN INTERACTIVE IMAGE-GUIDED NEUROSURGERY

Interactive image-guided surgery is the synchronous display of surgica l position on medical images during surgery. We have developed a techn ique for the dynamic display of surgical position on up to three indep endent sets of tomographic images. Each of these image sets may be com posed of square images of any size and are limited only by the size of the disk in the system. In addition to the raster images, a graphic d isplay is provided for visualization of relative position and surgical trajectory, or real-time intraoperative images may be used. This devi ce allows for improved 3-D surgical navigation and lesion margin defin ition.
