Fig. 4.

Signal and slice modulation field in scattered source space. Shown is an individual b=0 volume with relatively little motion and the b=0 source-space average signal as well as dStripe fields estimated in source space through-plane and inplane. Note that the averaged signal contains signal dropout and other artefacts that are suppressed by the motion correction algorithm and are therefore not accounted for in the dStripe field. Through-plane frequency constraints apply in “slice-native” space, high-frequency variations are not enforced in source space shown here.
