尽管有许多临床和实验应用，经颅磁刺激技术仍然存在模糊的方面。这尤其涉及安全参数和由单个磁脉冲感应的电流的精确表征。该模型由一个等效的电网络推导出的麦克斯韦方程组和应用到离散化的磁共振成像的正常受试者。该模型允许准确预测电流分布、每相电荷和耗散能量。
In spite of many clinical and experimental applications, the technique of transcranial magnetic stimulation still presents obscure aspects. This especially concerns safety parameters and the exact characterization of the current induced by a single magnetic pulse. The model proposed consists of an equivalent electric network derived by Maxwell's equations and applied to discretized magnetic resonance imaging of a normal subject. This model allows accurate prediction of current distribution, charge per phase and dissipated energy.
