Abstract

This paper studies induced electric fields and current densities for peripheral nerve stimulation (PNS) induced by breast gradient coils. The numerical calculations are based on an efficient, quasi-static, finite-difference (QSFD) scheme. The application of the human body to the calculations of induced current densities and electric fields from applied low frequency magnetic and electric fields is described. The spatial distributions of the induced electric field and their gradients are calculated. This study provides some insight into the spatial characteristics of the induced field gradients for PNS in MRI, which may be used to further evaluate the sites where magnetic stimulation is likely to occur and to optimize gradient coil design.
