摘要： To conduct magnetic resonance imaging (MRI) radio frequency (RF) pulses including a plurality of frequency components and a selection gradient are applied to a target to simultaneously excite a plurality of sub-volumes included in each of at least two groups. The groups are formed such that any neighboring sub-volumes of the plurality of sub-volumes constituting the volume of the target belong to different groups. Magnetic resonance signals are acquired from the plurality of sub-volumes by performing 3D encoding on each of the excited sub-volumes. The acquired magnetic resonance signals are reconstructed into image data corresponding to each of the plurality of sub-volumes.
