A numerical method based on stream function Singular Value Decomposition is proposed for optimization of Multi-Coil array (MCA) design for human brain shimming. It provides geometries other than circles for shim loops and halves the amount of channels needed to achieve the same whole-brain inhomogeneity reduction as current MCA systems. Strong impacts are expected for imaging and spectroscopy at Ultra-High Field.
