Design of human brain shim coil with high-density wire pattern translated from Stream Function

In this work, we propose a B0 shim coil design method based on high-density wire pattern discretized from stream function optimization. We demonstrate that the magnetic field generated by the designed shim coil can fully match the theoretical magnetic field generated by continuous stream functions. We compared the performance of different current-carry surfaces over shim ability for stream function optimization. We also evaluated the impact of current limitation for the discretized coil on B0 shim result and power dissipation.
