The first realization of full zero- to third-order DSU with full preemphasis and B0 compensation is presented which allowed high quality shimming of the human brain at 7 Tesla. The achievable magnetic field homogeneity could be largely improved not only in comparison to global (i.e. static) zero- to third-order shimming, but also when compared to state-of-the-art zero- to second-order DSU.
