However, this method causes discomfort and anxiety for patients. The development of surface imaging (Surface Guided Radiation Therapy, SGRT) could offer a solution to this problem. SGRT is a non-invasive and non-ionizing imaging technique that uses cameras to capture the patient's position in real-time. In mask-free treatment, the radiation beam can be interrupted when motion exceeds a certain threshold and restarts only when the position is corrected.\n\nNowadays, very few studies have examined the concept of radiation therapy without immobilization masks using SGRT.\n\nAs part of this study, participants will take part in a simulated mask-free session. We will determine the stability of the patient's position in the absence of a mask. Participants will also complete questionnaires concerning their feelings during sessions with and without masks.",[28],{"label":29,"type":30,"description":31,"interventionNames":32},"Radiotherapy session without mask","EXPERIMENTAL","A radiotherapy session without a mask will be simulated twice (during the first week and last week of treatment) during two scheduled treatment sessions.",[33],"Device: Surface Guided Radiation Therapy without mask",[35],{"type":36,"name":37,"description":38,"armGroupLabels":39,"otherNames":20},"DEVICE","Surface Guided Radiation Therapy without mask","Patients are positioned using SGRT based on the reference position reconstructed from the simulation scanner.
