[目的]对“野中野”治疗计划中同角度下多个适形野合并后同合并前的执行结果比较。[方法]对10位患者制作“野中野”治疗计划,然后用瓦里安MLC生成软件SHAPER将“野中野”治疗计划中同角度下多个适形野合并为一个静态调强野,并将人工修改的静态调强野和原始的野中野计划中的适形野在加速器上执行,用二维电离室矩阵MatriXX对合并前和合并后计划的执行结果进行测量,并用OmniPro-I’mRT软件分别用1%/1mm、2%/2mm、3%/3mm三种标准进行Gamma比较分析。[结果]合并后的静态调强野的MLC文件可以被加速器正常调用,3种分析标准下的Gamma比较结果均值都超过99.9%。[结论]人工合并射野后并不影响两种不同的治疗计划在加速器上的执行剂量分布。
[Objective] To compare the results of merging multiple merging fields under the same angle with the “Yezhongye” treatment plan before the merger. [Methods] Ten wild patients were treated with “wild field” treatment plan, and then combined with Varian MLC software SHAPER to make multiple “wild fields” Field, and manually modified static field and wild Yano program in the wild on the accelerator field execution, using two-dimensional ionization chamber matrix MatriXX pre and post-merger plan to measure the results and use OmniPro- I’mRT software respectively 1% / 1mm, 2% / 2mm, 3% / 3mm Gamma comparative analysis of three criteria. [Result] The MLC file of the combined static I / O field can be invoked normally by the accelerator. The mean values of Gamma comparison under the three kinds of analysis standards all exceed 99.9%. [Conclusion] Artificial merging of the field did not affect the implementation dose distribution of the two different treatment plans on the accelerator.
