Uniform oscillating gradient produced by spherical birdcage resonator.
The theory and operation of a resonator which produces a uniform oscillating magnetic field gradient is described. When the resonator is operated at audio frequency, it will produce the oscillating magnetic field gradient required for use in spatial encoding in rapid acquisition magnetic resonance imaging.
