Anthropomorphic computational phantoms are used to numerically estimate the potential envelope of intensity and distribution of induced E-fields in patients undergoing MR examination. The impact of anatomical variation of the phantom on medical implant risk assessment is demonstrated for generic transfer functions and lead trajectories representing pacemaker, DBS, SCS, and cochlear implant routings. Results showed that even when only one generic transfer function was considered, each of the 12 anatomical phantoms represented the worst-case for at least one configuration. Thus, the widest available range of anatomical phantoms must be examined to define a conservative safety envelope.
