Single-sided Quadratic Phase Outer Volume Suppression Pulses

Quadratic phase outer volume suppression (OVS) pulses have high selectivity and low peak RF value. Following the weighted least squares algorithm proposed by LeRoux et al., we design single-sided quadratic phase OVS pulses, which maintain the high selectivity at one side of the passband, while treating the opposite side of the passband as a dont care region. By sacrificing symmetry in the pulse to produce quadratic phase in the dont care region, single-sided OVS pulses offer a 10-20% lower peak RF power compared to their double-sided counterparts.
