Fig. 3 — Detector intrinsic sensitivity expressed as the gamma pass rate for the measured dose distribution with introduced‐variations in delivery vs measured baseline plans with no variation/no error (NE). Average gamma pass rate of the baseline (NE) plans and simulated variations in collimator angles and MLC using ArcCHECK; composite arcs/plan measurements (left column; a–c) and ArcCHECK; individual arc measurement ARC1 and ARC2 (right column; d–f) with different gamma criteria. The error bars represent the standard deviation (±1SD) of the measured plans. Correction added on May 28, 2021 after first online publication: Figure columns have been updated as ArcCHECK Composite Arcs (above left column: a‐c) and ArcCHECK Individual Arc (above right column: d‐f).
