5524 Evaluation study of MRI compatible robot based on MRI image and electromagnetic wave measurement
Details
Development of surgical mechatronics system under MRI environment is now becoming popular to realize minimally invasive treatment. We're developing the MRI compatible needling surgical robot with ultrasound motors to move inside the MRI gantry. In this paper, we focus on the leakage of electromagnetic-wave as the newly evaluation method of MR compatibility. We coped with electromagnetic waves by covering the actuators with aluminum shields. S/N ratio and the distortion caused by the manipulator was evaluated and the results indicated that our robot has highly MR compatiblity inside the MRI gantry.
