The structural similarity of the head model affects the accuracy of forward solution to electrical impedance tomography (EIT). Generally, the four-concentric circle model (FCCM) is used as the head model, which ignores the inhomogeneous distribution of the conductivity of real skull. In order to dec

Abstract
This paper introduces a new reconstruction algorithm for electrical impedance tomography. The algorithm assumes that there are two separate regions of conductivity. These regions are represented as eccentric circles. This new algorithm then solves for the location of the eccentric circles. Due to the simple geometry of the forward problem, an analytic technique using conformal mapping and separation of variables has been employed. Β© 2002 John Wiley & Sons, Inc.

## Abstract The forward problem of electrical impedance tomography on unbounded domains can be studied by introducing appropriate function spaces for this setting. In this paper we derive the pointβwise asymptotic behaviour of weak solutions to this problem in the threeβdimensional case. Copyright
## Abstract This article is concerned with the shape reconstruction for the inviscid fluid governed by the Euler equations. By formulating the domain derivative of the Euler equations and applying a regularized GaussβNewton iterative algorithm, the numerical examples are given for recovering the sh
An electrical resistance tomography (ERT) technique is suggested to monitor a radioactive waste separation process. This paper presents analytical results for a simple model problem to estimate the boundary between two distinct waste streams in a rotating separator as well as the conductivity value
