Claim 11:
12. A system, comprising:
at least one storage device including a set of instructions; 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 directed to perform operations including:
for each slice of a plurality of slices of a subject to be scanned, determining a plurality of radiofrequency (RF) parameters, the plurality of RF parameters including at least one channel parameter corresponding to each of a plurality of channels, the at least one channel parameter corresponding to each of the plurality of channels including an excitation power of the channel for exciting the slice;
determining a slice group based at least in part on the RF parameters corresponding to the plurality of slices, the slice group including at least two slices selected from the plurality of slices, wherein the determining a slice group based at least in part on the RF parameters corresponding to the plurality of slices includes:
selecting a first slice to be excited from the plurality of slices;
for each of the plurality of channels, determining a power difference between a power threshold of the channel and the excitation power of the channel for exciting the first slice;
determining at least one first candidate slice based on the power difference corresponding to at least one of the plurality of channels; and
determining the slice group based on the first slice and the at least one first candidate slice; and

directing at least a portion of the plurality of channels to excite the slice group based on RF parameters corresponding to the slice group.
