3D modeling of the induced electric field of transcranial magnetic stimulation

Abstract

The objective of our study was to make use of the MQS solver available under SEMCAD-X simulation environment and the high-resolution 3D head-and-brain model available through the IT'IS Foundation, to make a full 3D analysis of the TMS procedure. The electromagnetic field induced by two typical stimulating coils has been modeled, and their efficiencies compared. The comparison was made based on the distributions of the induced electric field, the activation function and the induced current density distribution. © 2009 Springer.
