Magnetic resonance imaging system and magnetic resonance imaging method

A method of magnetic resonance imaging (MRI), the MRI method comprising:

• reconstructing image data corresponding to each of a plurality of sub-volumes included in any one of a plurality of groups by applying a predetermined pulse sequence to a target, wherein neighboring sub-volumes of all sub-volumes constituting a volume of the target belong to different groups;
• repeating the reconstructing of the image data for each group until the reconstructing of the image data has been performed for all groups constituting the volume of the target;
• and
• generating a 3D volume image by combining the image data corresponding to each of the plurality of sub-volumes included in each of the groups constituting the volume of the target after the reconstructing of the image data has been performed for all groups constituting the volume of the target.

A non-transitory computer-readable storage medium having stored thereon a program comprising instructions that when executed cause a processor to:

• apply radio frequency (RF) pulses comprising a plurality of frequency components and a selection gradient to a target to simultaneously excite a plurality of sub-volumes included in each of a plurality of groups, wherein neighboring sub-volumes of all sub-volumes constituting a volume of the target belong to different groups;
• acquire magnetic resonance signals from the plurality of sub-volumes by performing 3D encoding on each of the excited sub-volumes;
• and
• reconstruct the acquired magnetic resonance signals into image data corresponding to each of the plurality of sub-volumes.
