Transcranial magnetic stimulation (TMS) is a powerful non-invasive tool for investigating functions in the brain. The target inside the head is stimulated with eddy currents induced in the tissue by the time-varying magnetic field. Precise spatial localization of stimulation sites is the key of efficient functional magnetic stimulations. Many researchers devote to magnetic field analysis in empty free space. In this paper, a realistic head model used in Finite Element Method has been developed. The magnetic field inducted in the head bt TMS has been analysed. This three-dimensional simulation is useful for spatial localization of stimulation.
经颅磁刺激（TMS）是一种用于研究大脑功能的强大非侵入性工具。时变磁场在组织中感应出的涡流会刺激头部内部的目标。刺激部位的精确空间定位是有效进行功能磁刺激的关键。许多研究人员致力于在空的自由空间中进行磁场分析。本文开发了一种用于有限元方法的逼真头部模型。对经颅磁刺激在头部中感应出的磁场进行了分析。这种三维模拟对于刺激的空间定位很有用。
