In radiotherapy of cerebral tumors in the occipital, central, and parietal area it can be favourable to fix the patient's head in frontal or lateral position. It is true that this problem can be solved by manufacturing individual face masks of PVC with the vacuum deep-drawing method, but this method is very time- and cost-consuming. The present study suggests a simplified method using the thermoplastic polyester "Orfit". Such a mask provides a good immobilization and can be manufactured in 10 to 15 minutes without bothering much the patient. Simulation and computed tomography are not substantially affected by the material.
在对枕叶、中央区和顶叶的脑肿瘤进行放射治疗时，将患者头部固定在额位或侧位可能是有利的。诚然，这个问题可以通过用真空深拉法制作聚氯乙烯（PVC）的个性化面罩来解决，但这种方法非常耗时且成本高昂。本研究提出了一种使用热塑性聚酯“奥菲特”的简化方法。这样的面罩能提供良好的固定效果，并且可以在10到15分钟内制作完成，而不会给患者带来太多困扰。模拟和计算机断层扫描基本上不受该材料的影响。
