Fig. 13.

This figure shows the correlation between estimated and true FA for “normal” and “large” movements after correction of movements and distortions with eddy for the single-band data. The solid line shows results after correction using the volume-to-volume model and the dashed and dotted lines using the slice-to-volume model with 8 and 16 basis-functions respectively. A statistical test (testing for unequal slopes) was performed to assess whether the difference between the “normal” and “large” movements was greater for volume-to-volume correction compared to the pertinent slice-to-volume model. Significance was indicated with * ($p\le 0.05$), ** ($p\le 0.01$) or *** ($p\le 0.001$).
