We explore the local field control capability of a 48ch TMS coil array to perform B0 shimming in the brain. The array uses sixteen 3-axis TMS coils built using three independent orthogonal windings that provide added flexibility to orient the resultant magnetic dipole and thus facilitate tailoring the B0 shim field. We propose adapting the TMS coils to carry DC shim currents during EPI fMRI time series acquisitions to reduce artifact levels and improve the utility of TMS-fMRI for studying brain circuits.
