a: Coil sensitivities B1 magnitude of single-channel volume coil and magnitude profiles of two independent transmit channels. Position is expressed in terms of the linear off-resonance. The results of saturation on a 1D sample, for the (b) single-channel volume coil, (c) two adjacent coils playing an unmodified CHESS pulse, and (d) a pulse with optimized frequency. The two coil setup with optimized frequencies yields saturation over a broader range without the unwanted saturation band of water spins in the single-channel case.
