Last year we presented a novel whole-brain B0-shimming Multi-Coil Array design based on Stream Function Singular Value Decomposition on a cylindrical surface. Here this design is compared to more conventional single-layer matrix arrays in simulations based on a 100-subject B0-map database. While whole-brain shimming performance is naturally improved by our method, the effects of such optimization on slice-by-slice and region-specific shimming are not evident and are therefore explored in this work.
