Methods, systems, devices, and storage medium for magnetic resonance imaging

A method, comprising:

• obtaining first scanning data of a subject during a first scanning phase, the first scanning data corresponding to a first FOV;
• obtaining second scanning data of the subject during the first scanning phase, the second scanning data corresponding to a second FOV, and the second FOV being smaller than the first FOV;
• determining, based on the first scanning data and the second scanning data, a target correspondence between the first FOV and the second FOV of the subject in at least one motion state during the first scanning phase;
• and
• determining, based on the target correspondence, a target image of the subject during a second scanning phase.

A computer-readable storage medium storing computer instructions, wherein when reading the computer instructions in the storage medium, the computer performs a method including:

• obtaining first scanning data of a subject during a first scanning phase, the first scanning data corresponding to a first FOV;
• obtaining second scanning data of the subject during the first scanning phase, the second scanning data corresponding to a second FOV, and the second FOV being smaller than the first FOV;
• determining, based on the first scanning data and the second scanning data, a target correspondence between the first FOV and the second FOV of the subject in at least one motion state during the first scanning phase;
• and
• determining, based on the target correspondence, a target motion state of the subject during a second scanning phase.
