High-permittivity pads have proved effective for addressing B1+ inhomogeneities for neuroimaging at 7T and body imaging at 3T. In contrast with the ease of constructing these pads, obtaining an appropriate design involves sophisticated and time-consuming electromagnetic field simulations, meaning that in many applications this technique is not fully exploited. We have therefore developed an easy-to-use software tool which can be run on a standard desktop PC to design dielectric pads for 3T body and 7T neuroimaging applications.
