A novel technique for the magnetic field homogenization of the human brain is presented in which shim fields are synthesized by a combination of non-orthogonal basis fields from a set of individually driven, generic coils. First experimental results of dynamic multi-coil (DMC) shimming at 7 Tesla are shown to outperform state-of-the-art zero-to-third order spherical harmonic dynamic shim updating (SH-DSU)
