 Abstract: At high magnetic fields B0 inhomogeneities are more pronounced and B0 shimming becomes very important. Dynamic or slice based shimming always provides better results than global or shimming in a volume. For shimming in a small volume, we propose a setup composed of irregularly shaped coils. Performances of the proposed setup are compared to performances of the configuration composed of only loop elements. The setup with irregular coils shows improved performances over the setup containing only loop elements. Future work should validate performances of the proposed setup on different volume sizes and different brain’s B0 maps.
