Ten SBRT plans were selected for clinical evaluation: 1) Common clinical deviations based on the original SBRT plan (Plan0), including multileaf collimator (MLC) positioning deviation and treatment positioning deviation were introduced. 2) Compared the performance of the myQA SRS and a high\u2010resolution EPID dosimetry system in PSQA measurement for the SBRT plans.

The myQA SRS is highly sensitive in the detection of MLC deviations. The GPR of (3%\/1\u00a0mm) decreases from 90.4% of the original plan to 72.7%\/62.9% with an MLC outward\/inward deviation of 3\u00a0mm. Additionally, when the setup error deviates by 1\u00a0mm in the X, Y, and Z directions with the GPR of (3%\/1\u00a0mm) decreasing by an average of \u221220.9%, \u221225.7%, and \u221224.7%, respectively, and DPR (1\u00a0mm) decreasing by an average of \u221233.7%, \u221232.9%, and \u221229.8%. Additionally, the myQA SRS has a slightly higher GPR than EPID for PSQA, However, the difference is not statistically significant with the GPR of (3%\/1\u00a0mm) of (average 90.4%% vs. 90.1%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.414).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Dosimetry characteristics of the myQA SRS device meets the accuracy and sensitivity requirement of PSQA for SRS\/SBRT treatment.
