Intraoperative feedback for neurosurgical stereotactic laser system

A method for accurate intraoperative guidance of a surgical laser beam in neurosurgery is discussed. This method uses intraoperative ultrasound imaging and computer processing to control the movement of the laser. The method is described and images are shown. The system has been tested using data from intraoperative ultrasound imaging of cerebral tumors and simulated tumors of various shapes.<>
