Broadband RF pulses are of great interest for improving selectivity and reducing chemical shift displacements in localized spectroscopy. Slice-selective broadband refocusing pulses with immunity to B₁ variations are designed using optimal control theory. Pulses are optimized under energy constraints, are compared to a broadband SLR pulse, and applied in a PRESS experiment.
