摘要
目的比较IMSureQA和MatriXX两种计划验证工具，探讨IMSureQA软件在临床剂量验证中的可靠性。方法按随机抽样的抽签法选取10例调强放疗患者，分别用IMSureQA和MatriXX进行剂量验证，比较IMSureQA和MatriXX按3％，3mm标准进行分析后通过率的差异。结果IMSureQA验证方式经剂量计算模型得出，MatriXX的验证通过实际测量获得，验证的治疗计划以3％，3mm标准经y分析后得到其通过率，MatriXX的平均通过率为（97．9±0．6）％，IMSureQA为（98．1±0．8）％（t=0．86，P〉0．05）。结论IMSureQA可用来执行调强计划的验证。
Objective To compare IMSure QA and MatriXX for intensity modulated radiotherapy plans, and to investigate the credibility of IMSure QA software. Methods Ten patients receiving intensity modulated radiotherapy were randomly chosen for the quality assurance plans with 1MSure QA and MatriXX. Results The overall average of percentage pass points in 3% and 3 mm were （98. l ± 0.8）% with IMSure QA, and （97.9 ±0.6）% with MatriXX（t =0.86,P 〉0.05）. Conclusion IMSure QA can be a reliable verification tool for IMRT QA.
