目的：评价使用ExacTrac X射线系统（ETX）和无框面罩进行颅内立体定向放射外科手术的患者的分次内头部运动（IFM）：共有143例患者完成了IFM的治疗前检查，符合本研究的条件。B R408型无框面罩（Klarity Medical & Equipment Co.，有限公司，广州，中国），其覆盖头部的后部和整个面部，用于患者固定。在初始6D校正和第一次X射线验证（IFM 1）之后，每3分钟进行一次X射线验证，持续15分钟。
Purpose: To evaluate intrafractional head motion (IFM) in patients who underwent intracranial stereotactic radiosurgery with the ExacTrac X-ray system (ETX) and a frameless mask.Methods: A total of 143 patients who completed a pre-treatment examination for IFM were eligible for this study. The frameless mask type B R408 (Klarity Medical & Equipment Co., Ltd., Guangzhou, China), which covers the back of the head, and the entire face, was used for patient immobilization. After the initial 6D correction and first X-ray verification (IFM1), X-ray verification was performed every 3 min for a duration of 15 min. The IFMp (2
