Supplementary Fig. 1.

Color coded maps of the orientation of the principal eigenvector are displayed for the triggered (top middle) and non-triggered acquisitions obtained using OLLS tensor fitting (bottom left), as well as for the non-triggered acquisition after employing the iRESTORE algorithm (bottom right). Paired angular difference images of the principal eigenvectors' orientations are also presented. The white arrows indicate which of the acquisition/processing methods were compared; the angular difference maps are modulated by the respective FA difference maps.
