Reconstructing Small Perturbations In Electrical Admittivity At Low Frequencies

Keywords

electrical impedance tomography; frequency differential; small perturbation

Abstract

We present a method to recover small perturbations from constants in electrical conductivity σ and relative (to the air's) permittivity of a body, from electrical measurements at low frequencies at the boundary. The method is based on the asymptotic expansion of the frequency differential of the Neumann-to-Dirichlet map with respect to both frequency and perturbation size. To show its feasibility, we implement the method on two numerical experiments for a complete electrode model. © 2014 IOP Publishing Ltd.
