Abstract
A system acquires RF magnetic field information (B1 magnetic field information) in response to generated radio frequency (RF) pulses applied to a target object via at least one of a plurality of RF coil elements in a magnetic resonance imaging (MRI) system. The system acquires first information comprising B1 magnetic field phase information of a B1 magnetic field formed by the respective RF coil elements and acquires second information comprising B1 magnetic field phase information of a B1 magnetic field formed by a combination of two or more of a plurality of RF coil elements. The system acquires third information comprising B1 magnetic field phase information by combining the first information and the second information and processes the first, second and third information in providing a B1 map indicating spatial distribution of a B1 magnetic field.
