Studies have evaluated the viability of using open‐face masks as an immobilization technique to treat intracranial and head and neck cancers. This method offers less stress to the patient with comparable accuracy to closed‐face masks. Open‐face masks permit implementation of surface guided radiation therapy (SGRT) to assist in positioning and motion management. Research suggests that changes in patient facial expressions may influence the SGRT system to generate false positional corrections. This study aims to quantify these errors produced by the SGRT system due to face motion.

使用带有开放式面罩的SGRT量化由于面部运动引起的错误位置校正

研究评估了使用开放式口罩作为固定技术治疗颅内和头颈癌的可行性。这种方法可以给患者带来更少的压力，其精确度可与封闭式口罩相媲美。开放式口罩允许实施表面引导放射治疗（SGRT），以辅助定位和运动管理。研究表明，患者面部表情的变化可能会影响SGRT系统以生成错误的位置校正。这项研究旨在量化SGRT系统由于面部运动而产生的这些误差。
