N2 - Multiband pulses can have long durations, which can be reduced by applying the VERSE approach to optimise the combination of gradient and RF to make full use of available hardware performance. The resulting time-varying gradients are demanding and can lead to excitation errors on non-ideal gradient systems. In this work we incorporated the measured gradient impulse response function (GIRF) into an iterative VERSE design method and validated the result using simulation and experiments.
