To describe and implement a strategy for dynamic slice-by-slice and multiband B shimming using spherical harmonic shims in the human brain at 7T. For thin axial slices, spherical harmonic shims can be divided into pairs of shims (z-degenerate and non-z-degenerate) that are spatially degenerate, such that only ½ of the shims (non-z-degenerate) are required for single slice optimizations. However, when combined, the pairs of shims can be used to simultaneously generate the same in-plane symmetries but with diff
