Abstract:: 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.
