ABSTRACT:
A pair of coupled surface coils are arranged to provide active detuning whereby the shape of the RF field due to the RF current in one coil is modified in a calibrated fashion by the RF current in the second coil whereby a selected fraction of the RF field of one coil may be selectively added or substracted from the RF field of the one other coil thereby shaping the RF field.
