Abstract
An NMR system for producing images carries out a procedure in which field maps are produced that indicate inhomogeneities in the transmitted RF excitation field and inhomogeneities in the RF receive field. Intensity NMR data is acquired using a set of different RF excitation field strengths and separate transmit and receive arrays are produced by fitting a characteristic curve to the data. A variety of images which display RF inhomogeneities may be produced from these two arrays.
