SunCHECK软件在调强放疗计划剂量验证中的应用

目的:探讨SunCHECK软件在调强放疗计划剂量验证中的应用。方法:选取新疆医科大学第一附属医院已执行IMRT计划的40例患者，应用SunCHECK软件，对所接受数据进行单独计算，然后对原始放疗计划和QA计划进行Gamma分析。最后对QA计划与ArcCHECK测量结果进行Gamma通过率比较。结果:在SunCHECK软件单独计算结果中，Monaco计划平均Gamma通过率略高于Eclipse计划。相同计划系统原始计划与QA计划Gamma通过率没有差异。使用SunCHECK软件计算QA计划（包括Monaco计划和Eclipse计划）Gamma通过率略高于ArcCHECK测量结果的Gamma通过率。结论:SunCHECK软件符合IMRT计划剂量验证需要，给放疗质控工作带来了很大的便利性。无论是作为单独放疗计划验算工具，还是以log日志文件反推进行计划验证，都应该把SunCHECK作为质量保证程序的一部分。

Application of SunCHECK software in dose verification of intensity-modulated radiotherapy plan

Abstract: Objective To explore the application of SunCHECK software in the dose verification of intensity-modulated radiotherapy (IMRT) plan. Methods Forty patients who had completed IMRT in the First Affiliated Hospital of Xinjiang Medical University were enrolled. The received data were calculated separately by SunCHECK software, and the original radiotherapy plan were compared with QA plan for Gamma analysis. Finally, a comparison of Gamma passing rate between QA plan and ArcCHECK measurement results was carried out. Results The separate calculation results obtained by SunCHECK software showed that the Gamma passing rate of Monaco plan was slightly higher than that of Eclipse plan. For the same planning system, there was no difference in the Gamma passing rate between the original plan and QA plan. The Gamma passing rates of QA plans (Monaco plan and Eclipse plan) calculated by SunCHECK software were slightly higher than those of measurement results obtained by ArcCHECK. Conclusion SunCHECK software meets the needs of clinical dose verification of IMRT plan and brings great convenience to radiotherapy quality control. Whether it is used as a separate radiotherapy plan checking tool or plan verification based on log file, SunCHECK should be used as a part of quality assurance program.
