The aim of this study was to compare dose delivery of radiotherapy plans using Portal Dosimetry (Varian Medical Systems, Palo Alto, CA) and ArcCheck (SunNuclear, Florida) detector. Twenty modulated arc therapy (VMAT) plans were made in Eclipse Treatment Planing System (TPS). It is recommended to verify the dose delivery before treatment on the TrueBeam (Varian Medical Systems, Palo Alto, CA) accelerator to compare calculated dose on the TPS and delivered dose on the machine. Measurements were made using portal dosimetry (Amorphous silicon (a-Si)) and ArcCheck (diode) detector.
Figure 1. Results of dose delivery: Portal dosimetry and ArcCheck
Results of this study are showing the difference of 2% between measured dose on the two independent detectors and calculated dose on the TPS. Dose difference between measured and calculated dose is in accordance with the intrnational recommendations.
