目的：通过比较调强放疗剂量验证的结果，评价Monaco和Xio治疗计划系统的临床治疗准确性。方法选取Xio治疗计划系统20例鼻咽癌调强治疗计划，Monaco治疗计划系统20例鼻咽癌调强治疗计划，用IBA二维电离室矩阵Matrixx进行剂量验证，分别以2%/2 mm、3%/3 mm、5%/3 mm为标准进行Gamma通过率分析。结果 Monaco系统在3种标准下的Gamma平均通过率均高于Xio系统。差异在2%/2 mm、3%/3 mm下具有统计学意义（P<0.05），5%/3 mm下无统计学意义（P＞0.05）。结论两种治疗计划系统都能应用于临床调强放疗，但Monaco计划系统的准确性要优于Xio计划系统。
目的：通過比較調彊放療劑量驗證的結果，評價Monaco和Xio治療計劃繫統的臨床治療準確性。方法選取Xio治療計劃繫統20例鼻嚥癌調彊治療計劃，Monaco治療計劃繫統20例鼻嚥癌調彊治療計劃，用IBA二維電離室矩陣Matrixx進行劑量驗證，分彆以2%/2 mm、3%/3 mm、5%/3 mm為標準進行Gamma通過率分析。結果 Monaco繫統在3種標準下的Gamma平均通過率均高于Xio繫統。差異在2%/2 mm、3%/3 mm下具有統計學意義（P<0.05），5%/3 mm下無統計學意義（P＞0.05）。結論兩種治療計劃繫統都能應用于臨床調彊放療，但Monaco計劃繫統的準確性要優于Xio計劃繫統。

Objective To evaluate the clinical accuracy of Monaco and Xio treatment planning systems (TPS) by comparing the dose verification results of intensity-modulated radiation therapy (IMRT) of the two treatment planning systems.Methods The dose veriifcation of IMRT plans for nasopharyngeal carcinoma formulated by Xio TPS (n=20) and Monaco TPS (n=20) was conducted by IBA Matrixx. Then Gamma pass rate analysis was conducted according to various criterias including 2%/2 mm, 3%/3 mm and 5%/3 mm.Results The average Gamma pass rate of IMRT plans of Monaco TPS was higher than that of Xio TPS according to all the criterias. There were signiifcant differences between Monaco TPS and Xio TPS on the Gamma pass rate according to 2%/2 mm and 3%/3 mm criterias (P<0.05) while there were no signiifcant differences between the two treatment planning systems on the Gamma pass rate according to 5%/3 mm criterion (P>0.05).Conclusion Both of Monaco and Xio treatment planning systems can be applied to clinical IMRT while the accuracy of Monaco TPS is higher than that of Xio TPS.
