FIG. 8.

The angular deviation maps between the major eigen-vectors corresponding to the reference data and to the four reconstruction schemes in the splenium of the corpus callosum. The map of the major eigenvector reconstructed with method C in the absence of motion was chosen to be the reference dataset. In the case of no motion the deviation between the eigenvectors reconstructed with NLCG and reference is on the order of 2° (first row). When there is subject motion, NLCG performs generally better than CG SENSE, as shown by the lower angular deviation from the reference (third and fourth columns).
