Electromagnetic interference (EMI) between magnetic resonance (MR) imager and surgical manipulator is a severe problem, that degrades the image quality, in MR image- guided surgical robotic systems. We propose a novel motor driving method to acquire noise-free image. Noise generation accompanied by motor actuation is permitted only during the "dead time" when the MR imager stops signal acquisition to wait for relaxation of protons. For the synchronized control between MR imager and motor… CONTINUE READING
