摘要：This paper presents a hybrid direct search – quasi-Newton method for the inverse nonlinear problem of Electrical Impedance Tomography (EIT) in 2D domain. It belongs to the interior path methods. The Finite Element Method (FEM) is used to solve the forward EIT problem regarding the nodal scalar potentials and current density values. The variational approach is applied to solve the inverse problem. The preliminary knowledge about the inhomogenities in the domain is used.
