Fig. 2.

The distortion magnitude distribution at different diameters of spherical volumes around isocenter for each sequence and scanner. The dots mark the means and the lines mark the medians. The boxes define 25th and 75th quantiles, and red crosses are maximum outliers. Dashed gray line indicates distortion magnitude level of 1 mm. Scanners A-C are 1.5 T and D-E 3 T. The maximum value (16.0 mm) of 2D FSE sequence is not visible for Scanner C.
