Optical prospective motion correction requires that the position and orientation of the tracking system (typically a camera) is known relative to the reference frame of the MRI scanner. This provides a challenge for systems where the camera is frequently removed and reinstalled. One such example is when the camera is mounted on the head coil, which then moves in and out of the scanner with the patient table. In this work, we use simulations and in vivo measurements to investigate how precisely the camera needs to be repositioned in order to maintain good quality prospective motion correction.
