1. A method of generating an image of a subject using a magnetic resonance imaging (MRI) system having a processor comprising:
performing a scout scan on the subject to be examined using the MRI system, and obtaining phase data of a plurality of slice positions, wherein the scout scan is used to determine a region of interest for a diagnostic scan;
using the processor to:
determine three-dimensional space static magnetic field information according to the phase data of the plurality of slice positions;
determine a shimming value of a slice in the region of interest according to the three-dimensional space static magnetic field information;
determine a diagnostic scan parameter according to the shimming value;
performing the diagnostic scan of the subject in the region of interest using the MRI system according to the diagnostic scan parameter; and
generating the image of the region of interest.
