Optical Surface Guidance for External Radiotherapy of Head and Neck Cancer
Sponsor: Center Eugene Marquis
Summary
The goal of this clinical trial is to test the use of surface repositioning alone, without a restraint mask, during radiotherapy sessions for patients with head and neck cancer.

Surface Guided RadioTherapy (SGRT) without mask
Firstly, patients are positioned in a vacuum mattress that moulds their head, neck and shoulders for a reference scan. During the treatment sessions, patients are positioned according to the reference scan, using the surface camera system. Once the observed offsets have been applied, the patient's surface is captured. Treatment can then begin, with continuous monitoring of displacements by the surface camera system. Automatic beam interruption is provided during treatment in the event of motion detection exceeding the standard tolerance threshold (\>3 mm). If the use of a thermoformed mask during your treatment prove necessary, for whatever reason, will not result in a halt to the research. Patients receive between 10 and a max of 35 radiotherapy sessions. The follow-up period begins after the last radiotherapy session, and patients are assessed at 4 or 6 weeks and at 3 months by a radiotherapist.
