We purpose an integrated RF-shim coil array, where the shimming current path and the RF receiving coil are arranged on two orthogonal planes to minimize the mutual coupling. This design was implemented as an array consisting of seven shim coils and a 32-channel RF-shim array. The 39-channel RF-shim coil array has marginal SNR loss and improved the global shimming by 9%, compared to the 32-channel RF-shim array.
