TG\u2010119 and clinical benchmark cases were used to design IMRT\/VMAT plans. Verification plans were measured experimentally, and all plans were imported into RadCalc for secondary dose calculation. Triangular gamma analysis (3%\/2\u00a0mm) compared Monte Carlo\u2010simulated, measured, and TPS\u2010calculated doses. The optimal ARLFO was determined by weighted averaging of gamma pass rates. The model was validated on 10 clinical cases per site (head, thorax, abdomen, pelvis).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Commissioning identified the optimal ARLFO parameter as \u22120.02\u00a0cm (\u22120.02\u00a0mm). Under the gamma analysis criterion of 3%\/2\u00a0mm, the comparison between TPS\u2010calculated doses and Monte Carlo\u2010calculated doses for 10 clinical plans across four anatomical sites yielded: 98.9%\u00a0\u00b1\u00a00.8% (head and neck), 98.5%\u00a0\u00b1\u00a00.8% (thorax), 99.6%\u00a0\u00b1\u00a00.3% (abdomen), and 99.1%\u00a0\u00b1\u00a00.5% (pelvis).
