Measured leaf motion (left) and gamma pass rate (right) for modified dynamic multileaf collimator (MLC) leaf motion intensity modulated radiation therapy plans. Gamma pass rates fall dramatically once the introduced error exceeds the DTA criterion. While the detected leaf position correctly shows almost no shift when a wrong energy is used or jaw tracking is applied, the much lower predicted gamma pass rate shows the presence of an error.
