Comparison of the Effect of Coil Configuration and the Variability of Anatomical Structure on Transcranial Magnetic Stimulation

Transcranial magnetic stimulation (TMS) is a non-invasive technique that uses transient field generated from electromagnetic coils in inducing electric to stimulate the neurons of brain. Various researchers have proposed coil designs for TMS aimed at achieving high focality and increased penetration depth induced In this article, authors compare figure eight (FOE) coil, quadruple butterfly (QBC), triple halo (THC) on different head models confirm effect configuration field. Finite element simulations were conducted with Sim4life software determine maximum intensity, E-Max (V/m) stimulated volume brain, V-Half (m 3 ). The positioned model dorsolateral prefrontal cortex (DLPFC) location model, values compared variability anatomical structure.
