摘要
目的:观察分析头体一体式体位固定板在全中枢神经系统放射治疗中的优势。方法:回顾性分析20例使用螺旋断层放疗设备实施全中枢放疗的患者资料,其中10例使用了头体一体式体位固定板,10例使用了头体分体式固定板,将两组患者在治疗过程中各个方向的摆位误差数据进行分析。结果:头体一体式体位固定板组患者X轴和Y轴方向摆位误差显著小于头体分体式固定板组,其差异有统计学意义(t=3.489,t=4.750;P<0.05);Z轴方向摆位误差两组比较无显著差异。结论:头体一体式体位固定板在全中枢放疗时可以减小头脚方向的摆位误差,与螺旋断层调强放疗相结合可提高治疗精度,缩短治疗时间,值得在临床工作中广泛应用。
Objective： To observe the advantages of single head-body board in decreasing positioning error for cranniospinal irradiation. Methods： Twenty patients accepting craniospinal irradiation treated with tomotherapy. Ten of the patients used the head-board plus body-board separately to fix up the body in treatment, and another 10 used the single head-body board. The data of positioning error and side effects during the treatment were analyzed. Results： The positioning error in patients using head-body board was less than that using the head-board plus body-board in X and Y direction（t=3.489, t=4.750; P〈0.05）, and the compare data of the positioning error in Z directions had no statistical significance. Conclusion： The single head-body board can decrease the positioning error in superior-inferior direction for craniospinal irradiation, and it can shorten the treatment time, so it is worth wide usage in clinical treatment. The advice is to design different types and plastic models to fit patients with different ages and different body types.
