摘要： A method of parallel imaging for use with a magnetic resonance imaging apparatus includes producing a longitudinal magnetic field B0 throughout a target volume, producing a transverse magnetic field B1 that is generally perpendicular to B0 throughout the target volume, transmitting a plurality of RF pulses to the target volume, with a surface coil, acquiring first MRI data from a target within the target volume in response to the transmission of RF pulses, and with a body coil, acquiring second MRI data from the target within the target volume in response to the transmission of RF pulses, wherein acquisition of the first MRI data and the second MRI data occurs substantially simultaneously.

摘要： A system for magnetic resonance imaging an object is provided. The system includes a plurality of coil element groupings disposed within one or more RF coils, and a controller. The controller is operative to receive MR data from the object via the one or more RF coils, determine a g-factor for each of the coil element groupings of the plurality based at least in part on the MR data, and select a coil element grouping of the plurality based at least in part on the g-factors.
