Abstract: Systems and methods for MRI are provided. The methods may include 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; 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; 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.

Abstract: The present disclosure provides a system and method for image generation. The method may include obtaining a first image of a first modality representing a first region of a subject. The method may further include determining a second image of a second modality representing a second region of the subject based on the first image. The second region may include at least part of the first region of the subject. A slice direction of the first image may be the same as a slice direction of the second image. The method may further include generating a fused image by fusing the first image and the second image.
