Abstract
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
