Abstract
The volume of interest is excited. An array of pickup coils with water cores provide an array of signals whose frequencies indicate the magnetic field distribution. These frequencies are estimated and used to produce controlled magnetic field inhomogeneities which substantially cancel the undesired inhomogeneities in the field. The control signals can be stored and updated with each subsequent excitation.
