As MRI static fields get increasingly stronger, reducing $$$B_0$$$ inhomogeneities becomes more important but also challenging. When standard active shimming on commercial systems is insufficient for researchers’ needs, alternative approaches such as external shim or hybrid AC/DC coils can be used. However, in order to perform advanced shimming experiments, a proper software ecosystem is required and there is currently no open-source solution for transparent and reproducible shimming experiments. Here we introduce the Shimming Toolbox (, an open-source software package for performing and prototyping static, dynamic and realtime $$$B_0$$$ shimming experiments.
