摘　　要：目的:探索应用RayStation治疗计划系统脚本快速导出自定义剂量学统计指标的方法。方法:在RayStation 4.5治疗计划系统中,应用IronPython语言编辑脚本,利用判断语句判断器官类别,并据此分别读取或计算相应的剂量学统计指标数值,结合使用.NET框架,输出至Excel软件。结果:运行脚本后,在Excel中得到的靶区和危及器官的剂量学统计指标与手动从剂量体积直方图中获取的数值一致。结论:本方法摒弃了频繁手动读取剂量体积直方图上剂量学统计指标的操作,并实现了与Excel软件的交互,为临床及科研工作中统计分析病例剂量学参数提供便利,提高工作效率。Objective To explore a method for conveniently exporting the custom dose statistical indicators by using the scripting in Ray Station treatment planning system. Methods Scripting was edited with Iron Python in Ray Station 4.5 treatment planning system. The category of organs was firstly distinguished by using judgment statement, and the corresponding dose statistical indicators were directly read or calculated. Combined with the.NET framework, these values were exported to Excel software. Results After running scripting, the values of dose statistical indicators of target volumes and organs at risk in Excel were identical with those manually obtained from dose-volume histogram. Conclusion Without repeatedly manual operations of reading dose statistical indicators from dose- volume histogram, the proposed method achieves the interaction with Excel, and provides convenience for statistically analyzing the dose parameters of cases in clinical and research, improving the work efficiency.
