this work, we quantitatively studied the impact of the local shim coil to RF
coil in a combined B0 shim coil and RF coil system in terms of SNR, transmit B1+
and receive B1. By using the results as a design guideline, a 5-channel shim
coil was constructed, of which interferences on RF coils were minimized with
the appropriate shim coil diameters, number of turns and distances between the
shim coil and the sample.
