中文摘要：

目的基于脚本函数实现ART计划剂量评估的方法，使各版本PinnacleTPS均可以完成动态计划模块具有的放疗计划移植功能。方法首先编写并嵌入脚本。然后在后程影像空间设置照射等中心点。再通过执行脚本程序完成照射野导出、导入和设置权重．实现放疗计划在不同影像空间的移植。分别用本方法和PinnacleTPS的动态计划模块完成对1例鼻咽癌患者的ART计划评估．从计划参数和剂量学角度对比两种方法差异。结果与动态计划模块相比，通过本方法移植的放疗计划保持了前、后程计划参数的一致性。两种方法的等中心位置存在偏差，从而导致剂量分布不同。如果将两种方法生成的ART计划移植在相同等中心位置，则剂量分布结果完全一致。结论提出的ART计划评估方法准确、简便、易行，适用于各种版本PinnacleTPS，且不额外占用图像存储空间。该方法提高了评估自适应放疗剂量的灵活性和精度，也为开展临床及科研工作提供了技术支持。

英文摘要：

Objective To investigate the dose evaluation method for adaptive radiotherapy plans based on script functions, so that the function of radiotherapy plan transfer in the Dynamic Planning module can be completed by all versions of Pinnacle treatment planning system （TPS）. Methods The first step was to write and embed the scripts, and then the isoeenter of irradiation was set up in the late-course image space. The scripts were executed to export and import the radiation field and set up the weight, so as to realize the transfer of radiotherapy plan between different image spaces. This method and the Dynamic Planning module of Pinnacle TPS were used to evaluate the adaptive radiotherapy plan of one patient with nasopharyngeal carcinoma, and these two methods were compared in terms of plan parameters and dosimetry. Results Compared with the Dynamic Planning module, this method maintained the consistency in the fore- and late-course plan parameters of the radiotherapy plan. The two methods had different positions of the isocenter, which caused the difference in dose distribution; however, if the two methods transferred the adaptive radiotherapy plan at the same isocenter, the dose distribution was exactly the same. Conclusions This method for the evaluation of adaptive radiotherapy plans is accurate, simple, convenient, and applicable to all versions of Pinnacle TPS, and it does not take up additional image storage space. This method increases the flexibility and precision of radiotherapy dose evaluation and provides a technical support for clinical practice and research.
