FIG. 3.
A dual-band excitation pulse, targeting both water and fat under a homogeneous main field, was initially designed with the maximum gradient amplitude constraint of 5 mT/m, and the VERSE reshaping aimed to reduce the peak |B1,n| from 1.78 to 1. The VERSE pulse preserved the water profile but significantly distorted the fat profile, which was successfully corrected by the reVERSE pulse. Zoomed-in versions of central subpulses (indicated by the dotted boxes in Fig. a, g, and m) are compared for coil 4 in the gray box.
