Marker fixation remains an unresolved issue in Prospective Motion Correction (PMC) using optical tracking. The most common and simple approach to track motion of the skull is using markers adhered to the face. However, markers applied in this fashion can report erroneous positions due to facial gestures of the subject during the MR examination. The presented approach using multiple markers is a patient friendly solution, offering robust position data for PMC in the presence of facial gestures. The presented approach is a promising solution to stabilize prospective motion tracking and thus to significantly reduce costs for MR imaging facilities.
