Abstract

In spite of a large clinical and experimental application the techniques of transcranial magnetic stimulation still present obscure aspects. This concerns especially the safety parameters and the exact characterization of the current induced by a single magnetic pulse. The model proposed consists in an equivalent electric network derived by Maxwell´s equations and applied to discretized magnetic resonance imaging of a normal subject head. This model allows an accurate 3D prediction of current distribution.
