This study evaluated the gradient-induced heating of a
pair of metallic plates (dimensions similar to
commercial medical implantable pulse generators IPGs)
made of different materials in order to determine a
suitable test procedure for the test of gradient induced
heating. From the obtained results, it is observed that
a worst-case exposure cannot be concluded only by a
particular set of gradient field conditions for all
different implants.
