简要总结
The aim of this study is to investigate the technical feasibility of brain radiotherapy without immobilization masks using surface imaging to ensure accurate patient positioning and continuous motion monitoring.
详细描述
In brain radiotherapy, immobilization using a thermoplastic mask is a standard practice to ensure treatment accuracy. 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.
Nowadays, very few studies have examined the concept of radiation therapy without immobilization masks using SGRT.
As 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.

研究组 & 干预措施
Radiotherapy session without mask
A radiotherapy session without a mask will be simulated twice (during the first week and last week of treatment) during two scheduled treatment sessions.
干预措施: Surface Guided Radiation Therapy without mask (Device)
结局指标
主要结局
Stability of patient's position
时间窗: Through the course of radiation therapy (up to 6 weeks)
The stability of the patient's position will be assessed: * on the basis of "internal" movements (of the skull) detected by scanner imaging before and after the simulated session (on-board CBCT) * on the basis of surface movements monitored by SGRT throughout the session.
次要结局
- Patient's feelings with and without the mask(Through the course of radiation therapy (up to 6 weeks))
- Preference of treatment(Through the course of radiation therapy (up to 6 weeks))
