Time outside the motion estimates per volunteer. Relative time outside the motion estimates for NoOR, Min95 and MeanIE for the individual volunteers for the planning MRI (left) and the daily MRI (right) strategies. The percentages were determined per simulated treatment fraction and combined in the boxplots. Boxes: median value (line), mean (cross) and lower and higher quartiles; whiskers: lowest and highest data point in the 9–91% interval, the outliers are indicated by circles. For planning MRI: N = 97 included scans for analysis and N = 10 for constructing motion estimates; for daily MRI strategy N = 71 included scans for analysis and N = 36 for constructing motion estimates
