1. A system for magnetic resonance imaging (MRI), comprising:

  • at least one storage device storing executable instructions, andat least one processor in communication with the at least one storage device, when executing the executable instructions, causing the system to;

    obtain first image data of a first subject, the first image data indicating a first intensity distribution of a first magnetic field relative to at least one portion of the first subject;

    obtain a target machine learning model that provides a mapping relationship between second intensity distributions of second magnetic fields and corresponding second susceptibility distributions associated with second subjects under the second magnetic fields;

    generate a first susceptibility distribution associated with the first subject under the first magnetic field based on the target machine learning model and the first image data of the first subject; and

    determine a target MR image of the at least one portion of the first subject based on the first susceptibility distribution associated with the first subject.
