A magnetic resonance imaging (MRI) system comprising:
- a main magnet configured to generate a static magnetic field;
- a gradient coil configured to generate a gradient magnetic field;
- and
- a radio frequency (RF) coil arrangement comprising RF components corresponding to volumes representing target regions of a subject, each of the volumes comprising slices, each RF component comprising sets of RF coil elements, each set of RF coil elements being configured to apply RF fields to a slice of the corresponding volume, each of the RF components applying RF pulses having different frequencies to excite slices of different volumes simultaneously, and each of the RF coil elements being independently driven by an RF coil driving circuit, wherein a number of the slices is less than a number of the volumes and a number of coil elements in each set equals a number of the sets of the RF coil elements.
A radio-frequency (RF) coil arrangement for a magnetic resonance imaging (MRI) system, comprising:
- an RF coil arrangement comprising RF components, each RF component corresponds to one volume of volumes representing a target region of a subject and the each RF component comprising sets of RF coil elements, each of the volumes comprising slices, each set of RF coil elements corresponding to one slice of the slices of the volume of the corresponding RF component and being configured to excite the one slice, each of the RF components applying RF pulses having different frequencies to excite slices of different volumes simultaneously, and each of the RF coil elements being independently driven by an RF coil driving circuit, wherein a number of the slices is less than a number of the volumes and a number of coil elements in each set equals a number of the sets of the RF coil elements.
