Fig. 1 Beam-on time delivering single-arc treatments for all plans and beam qualities. The Box-and-whisker plot indicates the range of recorded treatment times based on all patients in each subgroup of plans. The solid line inside each box is the mean treatment time. The outliers of the data are shown as crosses (values deviating more than ±2.7σ).

Fig. 2 The fraction pass rate, with different gamma criteria, for the six different motion patterns compared to static measurement. The grey bars show the pass rate for the 10FFF plans and the black bars for the 10MV plans.
