Effects of head geometry, coil position and CSF displacement on field distribution under transcranial magnetic stimulation

Shahid, Salman and Wen, Peng and Ahfock, Tony and Leis, John (2011) Effects of head geometry, coil position and CSF displacement on field distribution under transcranial magnetic stimulation. Journal of Medical Imaging and Health Informatics, 1 (3). pp. 271-277. ISSN 2156-7018

Abstract

In this study the effects of a realistic head geometry, coil position and head orientation on the spatial distribution of induced electric field, under TMS, have been investigated using statistical modalities such as RDM, MAG and CC. It has been observed that the secondary electric field, caused by the asymmetry of the geometry, leads to a dramatic drop in E-field magnitude, causes deviation in field focality and accelerates its decay. The results show that the head geometry, coil position and head orientation play an important role in shaping the spatial distribution of induced electric field
