In the present study, as an add-on to commercial-available RF coils, a novel B0-shim coil design for local B0 shimming was proposed, based on which 8-channel B0-shim array has been designed to attach to Nova 1Tx/32Rx head coil for local B0 shimming at 7T. With minor interference to RF coil, the apparent improvement in local B0 shimming has been demonstrated by using the proposed attachable B0-shim array. The present setup offers a feasible and promising means for practical higher-order local B0 shimming technology. It is believed that the proposed approach could potentially merit a broad scope of researches such as clinical diagnosis and cognitive neuroscience.
