Prospective motion correction has demonstrated significant value for human brain MRI. One issue that all marker-based motion trackers share is the marker fixation to the human head. Short-wave motion tracking can solve this issue since the small wireless marker can directly be attached to the upper jaw with the mouth completely closed. In this work, we present PMC in-vivo imaging with such a sensor. The high temporal and spatial resolution can be observed in the measured physiological motion trajectories, illustrating the high-quality motion of this sensor.
