Abstract
Currently, MRI-guided neurosurgical procedures are performed in an operating room with open MRI, and intraoperative MR images are provided with real time rich biological information. However, it is difficult to perform procedure in MRI gantry. So, patient is moved out of MRI gantry when performed procedure. The MRI-compatible robots and navigation system for performing procedure in MRI operating room are developed. For precise surgery, actuators which can operate precisely in the MRI room is required. This paper proposed a prototype of pneumatic stepping actuator for MRI-compatible actuator. MR-compatible is required for actuators used in the MRI operating room. The actuators was developing 3D printer and evaluated the performance of repeatability.
