1. A system for magnetic resonance imaging (MRI), comprising:
at least one storage device including a set of instructions; and
at least one processor configured to communicate 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 auxiliary signals and a plurality of imaging signals collected by applying an MRI pulse sequence simultaneously to a plurality of slice locations of a subject; and
for each of at least one target slice location of the plurality of slice locations, generating, based on the plurality of auxiliary signals and the plurality of imaging signals, at least one target image of the target slice location, wherein
during the application of the MRI pulse sequence, phase modulation is applied to at least one of the plurality of slice locations so that the plurality of slice locations have different phases during the readout of at least one of the plurality of imaging signals, the phase modulation being applied via a phase modulated RF excitation pulse and/or a phase modulation gradient.
