Each marker corresponds to a brain region. When the coil is located 12 mm away from isocenter (left), the deviation of the main eigenvector of all brain regions is comprised between 3° and 11° degrees for highly isotropic regions. At a coil offset to isocenter of 18 mm (center), the eigenvector deviation is larger than at a 12 mm offset. Also, FA is more severely underestimated. When the coil is located at a 24 mm offset to isocenter (right), the deviation of the main eigenvector, as well as the underestimation of FA, are more severe.
