摘要

基于磁共振成像(MRI)技术，建立了真实形状的人头有限元模型。利用该模型，通过求解泊松方程的正演问题，模拟了在头皮表面施加注射电流时头部的电位和电流密度分布。在仿真结果和有限元模型分析的基础上，针对人体头部电阻率重建的特殊要求，提出了一种改进的建模方法，以获得最佳的仿真结果。

A realistically shaped finite element model of the human head for electric field simulation

A realistically shaped finite element (FE) model of the human head was developed based on magnetic resonance images (MRI). Using this model, the potential and current density distributions in the head were simulated by solving the forward problem of Poisson's equation when the injection current was applied on the surface of the scalp. Based on the simulation result and the FE model analysis, a modeling improvement is proposed in order to achieve the best simulation result for the particular requirements of the resistivity reconstruction of the human head.
