A markerless stereo optical system tracking
facial features such as skin textures and eyebrows, was developed. Despite the limited apertures of the head coil, the
optical system can track the volunteer’s facial features during scanning.

The four MR-compatible cameras record the patient’s face in the head coil
through the mirror.
