Analysis on the delivery quality assurance using SunCHECK for the VMAT in halcyon linear accelerator
This study evaluated the dosimetric accuracy of SunCHECK, a calculation-based IMRT DQA program, when applied to VMAT DQA for the Halcyon LINAC. Virtual VMAT treatment plans were generated utilizing a Delta4 Phantom + diode detector array device to analyze the accuracy of the dose calculation algorithm in SunCHECK. The analysis revealed a strong correlation between the calculated dose in SunCHECK, the planned dose, and the measured delivery dose. The characteristics of dose distribution changes calculated by SunCHECK in the event of MLC errors during VMAT beam delivery were analyzed additionally. After delivering a beam with MLC position errors, the dosimetric error evaluated through log file-based calculations were compared with the error analysis findings obtained from measurements using the Delta4 Phantom + . The dosimetric error calculated based on the log file using SunCHECK showed a similar trend to the dose error calculated through the conventional measurement-based DQA method using a Delta4 Phantom + . The results of this study validate SunCHECK’s accuracy in dose calculation and analysis of dosimetric errors resulting from MLC position errors, thereby confirming its efficacy in VMAT DQA using the Halcyon LINAC.
