 Abstract: A highly homogeneous B0 field is essential if we are to exploit the advantages of higher field strengths for MR applications. In this work, we model the real field of each shim channel of a 4th order shim system for a 9.4T MR system for in vivo B0 shimming applications. Each shim channel is modelled at a range of frequencies to account for the possibility of amplitude nonlinearities. By modelling the fields generated by each shim channel, we were able to achieve better shim qualities than if perfect fields were assumed.
