1. A magnetic resonance imaging (MRI) system, comprising:
at least one storage device including a set of instructions for dynamic MRI; and
at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
obtaining a plurality of sets of k-space data of a region of interest (ROI) of a subject, wherein each of the plurality of sets of k-space data is collected during one of a plurality of acquisition periods after an MR sequence is applied on the subject;
for each of the plurality of sets of k-space data,
determining, based on the set of k-space data, position information of a reference region during the corresponding acquisition period; and
correcting the set of k-space data based on the position information of the reference region; and
generating a dynamic MR image sequence based on the plurality sets of corrected k-space data.
