Abstract:
Objective:To explore the feasibility of RadCalc automatic planning validation system in the Monaco treatment plan system.Methods:The RadCalc automatic validation system was debugged,and the imaging data of 107 patients with tumors on head(29 cases),breast(28 cases),lung(28 cases)and abdomen(22 cases)who received radiotherapy at Xuanwu Hospital of Capital Medical University from 2021 to 2023 were screened.The dose γ passing rates were tested for all patients.The RadCalc automatic validation system was used to validate the dose γ passing rate under the 3%/2 mm and 3%/3 mm criteria of the radiotherapy plan,and the measured results were compared with those from ArcCHECK and MatriXX phantom.Results:The dose γ passing rates of all debugged test field were more than 97%.In the dose test of clinical plan of 107 patients,the mean value of all dose γ passing rate was larger than 96%under the 3%/2mm criteria,and that was larger than 98%under the 3%2 mm.There were significant differences in the dose γ passing rates under 3%2 mm and 3%3mm criteria of head plan,and under 3%3 mm criteria of breast plan between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system,and the differences were statistically significant(t=8.02,7.79,3.32,P<0.05).There were no significant differences in the γ-passing rate under 3%/2 mm and 3%/3 mm criteria of breast plan and abdomen plan between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system(P>0.05).In volumetric intensity modulated arc therapy(VMAT)plan,there were significant differences in dose γ passing rate under 3%/2 mm and 3%/3 mm criteria between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system(t=4.61,5.16,P<0.05),while there were not statistical significance in these indicators between them in intensity modulated radiation therapy IMRT plans(P>0.05).Conclusion:The measured results of the RadCalc automatic validation system has favorable consistency with the measured results of ArcCHECK and MatriXX phantom.The RadCalc automatic validation system can be used in dose validation of clinical plan.
