Real time motion correction using an external optical tracking system has been suggested as a way to perform rigid head motion correction for MRI. In this study, we demonstrated the motion correction efficacy of our real-time monovision system that uses a single camera mounted inside the magnet bore on the head coil. Experiments were carried out using a gradient echo and a spin echo sequence with the subject performing varying degrees of in-plane and through plane motion. The results show that the current system is effective in removing both in plane and through plane motion.
