Title

Feasibility study of multi-purpose quality assurance phantom for pretreatment verification of volumetric modulated arc therapy

Pages

  279-287

Abstract

 Background: The purpose of this study was to evaluate the feasibility of a mul-purpose quality assurance (QA) phantom for pretreatment verifica on of Volumetric modulated arc therapy (VMAT). Materials and Methods: The QA phantom was constructed with polymethyl methacrylate (PMMA) to perform rela ve dosimetry using EBT3 film and MapCHECK, as well as absolute dosimetry using an ioniza on chamber. The QA phantom was constructed to perform rela ve dosimetry using EBT3 film and MapCHECK, as well as the absolute dosimetry using ioniza on chamber. In order to verify the pretreatment plans, 25 pa ents treated with VMAT were selected. The pretreatment plans were calculated in the Eclipse treatment planning system using the Acuros XB dose calcula on algorithm and CT images for the QA phantom, with the same beam setup and monitor units (MUs) as those for pa ent treatment. All plans were delivered to the Varian TrueBeam accelerator equipped with a high-defini on mul-leaf collimator. Results: The mul-purpose QA phantom is developed for convenient VMAT dose verifica on. By using the QA phantom, all 25 cases passed ± 3% acceptability criteria in absolute dosimetry with an ioniza on chamber for pretreatment verifica on. The rela ve dosimetry using EBT3 film and MapCHECK system also showed high agreement of more than 90% for 2%/2-mm and 3%/3-mm criteria. Conclusion: The results of this study demonstrated the good mul-purpose capabili es of the phantom for the absolute and rela ve dosimetry. Therefore, the developed mul-purpose QA phantom was applied in our ins tu on for rou ne VMRT dose verifica on.
