The aim of the study was to investigate the clinical feasibility of whole-brain radiation therapy without a thermoplastic mask. Positioning and intra-fractional motion monitoring were performed using optical surface scanning. The motion threshold was 3 mm/3 degrees. The group mean vector deviation was 1.1 mm. The roll was larger compared to pitch and rotation. Two patients out of 30 were not able to lie still. All other patients completed their treatment successfully without a mask. With a probability of success of 93%, we concluded that irradiation without a mask is a clinically feasible method.
本研究的目的是探讨不使用热塑性面罩进行全脑放射治疗的临床可行性。使用光学表面扫描进行定位和分次内运动监测。运动阈值为3毫米/3度。组平均矢量偏差为1.1毫米。横摇比纵摇和旋转更大。30名患者中有2名无法保持静止。所有其他患者均未使用面罩成功完成治疗。成功率为93%，我们得出结论，不使用面罩进行照射是一种临床可行的方法。
