Fig. 3.

Distortion magnitude distortion versus length of volume-of-interest along z-axis. The dots mark the means and the lines mark the medians. The boxes define 25th and 75th quantiles, and red crosses are maximum outliers, of which values >10 mm are omitted for visualization purposes, but are given as text. Dashed gray line indicates distortion magnitude level of 1 mm. Scanners A-C are 1.5 T and D-E 3 T. The whisker of 2D FSE sequence ends at 11.0 mm for Scanner C.
