ELECTROIMPEDANCE TOMOGRAPHY AS A TOOL FOR BRAIN EXAMINATION

Abstract

The aim of this paper is to discuss the possibility of a successful Electroimpedance Tomography (EIT) reconstruction of an impedance distribution within a human head taking into consideration the presence of a skull and its screening effect for electrical signals. The results of numerous computer simulations of the processes of impedance measurements and 3D EIT reconstruction are presented. The volume of the smallest recognisable perturbation within both brain and skull areas are determined as well as their relationships with the required contrast. The unquestionable usefulness of EIT approach for the purposes of impedance modelling is proven.

Keywords:

electroimpedance tomography, EIT, impedance modelling, EEG propagation analysis, head model
