摘要:
目的:快速比较计划系统建模后百分深度剂量(PDD)和离轴剂量(OAD)的计算值和测量值以及每年加速器年检中两次测量值的PDD和OAD,用以判断加速器建模数据准确性和测量数据一致性。方法:运用基于面向对象Python程序开发了基于IAEA 430号报告的比对软件ComparePO(CPO),该软件由文件准备、PDD模块、OAD模块、比对参数可视化和报告生成模块构成。结果:在临床上首先验证CPO的运行情况和结果报告的正确性,其次对新安装的两台加速器验收和加速器机头更换电离室后的数据测试都用到了该软件,该软件都能快速得出PDD和OAD的比较报告,为放射治疗物理师提供判断指导。结论:该软件界面友好,功能强大,能快速计算生成PDD和OAD比较报告,大大节约核查时间,提高放射治疗物理师的工作效率。
Abstract:
Abstract: Objective To realize a rapid comparison between calculated and measured percentage depth dose (PDD) and off-axis dose (OAD) after the modeling by treatment planning system as well as the comparison of different measurements during the maintenance of medical accelerators once per year for determining the accuracy of accelerator modeling data and the consistency of measurements. Methods Object-oriented Python program was used to develop a ComparePO (CPO) software for PDD and OAD comparisons according to IAEA technical report series No.430. CPO was composed of document preparation module, PDD module, OAD module, comparison parameter visualization and report generation module. Results The successful execution of CPO in clinic and the accuracy of reports were firstly verified. Secondly, CPO was utilized for the quality maintenance of two newly installed accelerators and the dose data testing after ionization chamber replacement. The reports of PDD and OAD comparisons were quickly generated by CPO, thereby proving guidance for radiation therapy physicists. Conclusion CPO which is a user-friendly and powerful software is able to generate comparison reports of PDD and OAD automatically and rapidly, significantly shortening checking time and improving the working efficiency of radiation therapy physicists.
