Ultra-high-field MRI is more sensitive to variations in the B0 field specially for larger organs such as the liver. Dynamic shimming using a local array of shim coils can potentially improve the field homogeneity by 18-46% when compared to the standard hardware correction methods at 7T. The use of local shim coil arrays embedded in RF receiver coils may become a good strategy when maximizing shim performance considering the limited available number of shim channels, particularly for larger organs such as the liver at ultra- higher field strengths.
