Single-sided Quadratic Phase Outer Volume Suppression Pulses
Stikov N, Cunningham C, Lustig M, Pauly J
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.
