针对实际头模型的高分辨脑电解卷问题 ,本文在曲线坐标系下采用有限体元法 ,提出一种新的由头皮电位逆推皮层电位分布的新方法。方法以文中推导出的十八邻点有限电阻网络模型和超松弛迭代算法为基础。仿真计算和对实际测量数据的分析均证实方法的可行性。
In order to solve the problem of high resolution brainwave volume in the real head model, a new method based on the finite element method is proposed in curvilinear coordinates to reverse the scalp potential to reverse the cortical potential distribution. The method is based on the eighteen neighbors finite resistance network model derived from the paper and the over-relaxation iterative algorithm. The simulation calculation and the analysis of the actual measurement data confirm the feasibility of the method.
