Slice-wise dynamic shimming is used in ultra-high-field MRI research due to its capability to produce a more homogeneous field than static shimming. This work presents a field-map-free approach to first-order dynamic shimming, which can reduce the time spent on shim determination compared with field-map-based approaches, whilst still outperforming static shimming.
