头颈部肿瘤外照射面模固定装置的研究张有望，吴永和，胡超苏放射治疗头颈部肿瘤一直沿用枕头米袋固定法，方法简便，但照射野移动率高达４０－８０％。照射野移动将影响靶区剂量，使肿瘤控制率下降，正常组织和重要器官放射并发症增加。我科采用国产医用热塑板材料、制作... Study on Head and Neck Tumor External Surface Mount Fixtures Zhang Youwang, Wu Yonghe, Hu Chaosu Radiation therapy for head and neck tumors has been carried out using a pillow rice bag fixation method. The method is simple, but the radiation field mobility is as high as 40-80%. Irradiation field movement will affect the dose in the target area, so that the tumor control rate will decrease, and the radiation complications of normal tissues and vital organs will increase. Our department uses domestic medical thermoplastic board materials, making...
