An RF coil assembly includes a plurality of RF source coils and an RF
target coil separate from the plurality of RF source coils. A computer is
programmed to acquire MR data of an imaging object from each of the
plurality of RF source coils and to acquire MR data of the imaging object
from the RF target coil. The computer is further programmed to calculate
a set of weights based on a relationship between MR data acquired from
each RF source coil and MR data acquired from the RF target coil and to
reconstruct an image based on an application of the set of weights to at
least a portion of the MR data acquired from each of the plurality of RF
source coils.
