Distances outside motion estimates. Histograms of the relative frequencies the observed motion in the simulated treatment fractions were at a certain distance outside the motion estimates, for planning MRI and daily MRI for NoOR, Min95 and MeanIE. The bars show the median of all volunteers (N = 10) for that distance and the error bars the range. Dotted lines indicate the distances within which 90%, 95% and 99% of the data is included. 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
