A method and system for homogenizing a main magnetic field of a magnetic resonance imaging ("MRI") system includes obtaining a main magnetic field distribution generated by the MRI system, obtaining at least one shim magnetic field distribution generated by at least one shim coil of the MRI system, and determining a corresponding shim current based on a relationship between the main magnetic field distribution and the at least one shim magnetic field distribution.
