Shim current calculation When shim coils are excited by appropriate current, they can generate correcting magnetic field to compensate the imaging magnetic field unhomogeneity. Based on the indirect calculation method, we proposed a novel iterative optimization algorithm to calculate shim current.

Shim current can be worked out in less than 3 minutes. This satisfied the requirement that active shimming should be performed in real time.
