Claim 10:
11. The method according to claim 3, further comprising:
selecting, from the plurality of slice positions, a predetermined number of slice positions close to the position of the slice in the region of interest,
and the steps of determining three-dimensional space static magnetic field information according to the phase data of the plurality of slice positions, and determining a shimming value of a slice in a region of interest according to the three-dimensional space static magnetic field information comprise:
performing high-order polynomial fitting on phase data of the predetermined number of slice positions, to obtain three-dimensional space static magnetic field information corresponding to locally continuous slice positions; and
determining, from the three-dimensional space static magnetic field information corresponding to the locally continuous slice positions, the shimming value corresponding to the slice position in the region of interest.
