Cameras track the patient's skin surface in three dimensions during treatment, replacing tattoos and pausing the beam if the patient moves.
Optical surface tracking systems project structured light onto the patient and compare the reconstructed surface with the planned one many times a second. They set up the patient without permanent skin tattoos, monitor motion throughout the beam and gate delivery during breath-hold. Surface guidance is now routine in breast radiotherapy, where deep-inspiration breath-hold moves the heart out of the field, and in radiosurgery with open face masks.
Real-time comparison of the patient's 3D surface with a reference surface drives setup corrections and beam gating.
