—This paper presents a new approach to robot-assisted spine and trauma surgery in which a miniature robot is directly mounted on the patient's bony structure near the surgical site. The robot is designed to operate in a semiactive mode to precisely position and orient a drill or a needle in various surgical procedures. Since the robot forms a single rigid(More)
This paper describes a novel image-guided system for precise automatic targeting in minimally invasive keyhole neurosurgery. The system consists of the MARS miniature robot fitted with a mechanical guide for needle, probe or catheter insertion. Intraoperatively, the robot is directly affixed to a head clamp or to the patient's skull. It automatically(More)
This paper is part of an ongoing effort to develop a novel image-guided system for precise automatic targeting in keyhole minimally invasive neurosurgery. The system consists of a miniature robot fitted with a mechanical guide for needle/probe insertion. Intraopera-tively, the robot is directly affixed to a head clamp or to the patient skull. It(More)
We present a clinical study of surface-based registration between a preoperative CT/MRI of a patient head and an intraoperative surface scan of his face. The study was conducted on 14 patients that underwent neurosurgery with standard neuronavigation based on preoperative CT/MRI datasets. Intraoperatively, before the surgery started, surface scans of the(More)
