摘要

本文提出了一种迭代灵敏度矩阵法来估计区域头部组织电导率。导出了二维同心圆模型的电阻抗层析成像正演问题的解析解。通过2-D 3层同心圆模型和3- d 4层球面模型验证了该估计，可以在较少的迭代次数和计算时间内获得收敛性

Regional head conductivity estimation by the iterative sensitivity matrix method

In this paper, an iterative sensitivity matrix method is proposed to estimate the regional head tissue conductivity. The analytical solution of the electrical impedance tomography (EIT) forward problem is derived for a 2-D concentric circular model. The estimation is verified by a 2-D concentric circular model with 3 layers and a 3-D spherical model with 4 layers, the convergence can be obtained with less iteration number and computational time
