A matrix array shim coil system was designed to be included into a widebore gradient coil consisting of 24 channels in a 6 circumferential by 4 axial coil matrix array. The matrix shim coil is designed from multi-layer Kapton circuit boards and is integrated into a gradient coil between the inner and outer gradient coil. Simulations from brain images were analyzed and demonstrate improved performance over a traditional 3rd order harmonic shim set.
