1. A method for magnetic resonance imaging (MRI) implemented on a computing device having at least one processing device and at least one storage device, the method comprising:
obtaining a plurality of imaging signals collected by applying a wave encoding gradient to a region of interest (ROI) of a subject;
obtaining a plurality of auxiliary signals associated with the ROI;
obtaining a point spread function corresponding to the wave encoding gradient;
determining, based on the plurality of auxiliary signals, temporal information relating to at least one temporal dimension of the ROI, the temporal information including at least one temporal basis function relating to the at least one temporal dimension;
determining, based on the temporal information, the plurality of imaging signals, and the point spread function, spatial information relating to at least one spatial dimension of the ROI, the spatial information including at least one spatial basis function relating to the at least one spatial dimension; and
generating at least one target image of the ROI based on the temporal information and the spatial information.
