Abstract
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.关键词
