B0 field inhomogeneity can reduce the effectiveness of RF pulses, result in signal voids, blurring and image artefacts. Integrated RF-shim coil arrays1,2,3 offer capabilities for concurrent parallel RF reception and local B0 shimming, and is superior to spherical harmonic shimming. However, its performance may still be limited due to the lack of flexibility for shimming and limited depth penetration for signal reception. We simulated the B0 shimming performance of a range of integrated RF-shim coil arrays with 3D orthogonal loop coil geometry, and compared the results with standard 2D loop coil arrays.
