Whole brain resting state fMRI benefits greatly from shimming due to increases in BOLD sensitivity. This work presents a rapid shim calculation method using prior knowledge of nonlinear optimization results on a large database of field maps, which can significantly reduce the time spent on shim determination for BOLD sensitivity optimization, whilst delivering shim quality that is closer to the results of nonlinear optimization.
