Abstract: The present disclosure discloses a chemical shift coded imaging method based on a transition region and regional iterative phasor extraction. Acquiring an initial image, and determining an initial phasor solution of the transition region based on the initial image; performing regional iterative phasor extraction in at least two set directions by taking the initial phasor solution as initial information, and obtaining a target phasor solution based on a regional iterative phasor extraction result corresponding to each set direction; and determining a first chemical composition signal and a second chemical composition signal based on the target phasor solution, and performing chemical shift coded imaging based on the first chemical composition signal and/or the second chemical composition signal. By means of regional iterative phasor extraction in a plurality of dimensions, wrong phasor information is transferred independently along different dimensions, wrong information transferred in different directions is excluded.
