An efficient method for designing a reduced peak power dualband VSS pulse for application to clinical MRSI studies is presented. The approach is appropriate for incorporation during scan prescription which will allow for variable specification of band thickness, separation and tip-angle. The peak RF amplitude of the design is only 1.4 times that of a peak-power reduced single-band VSS pulse.
