Discusses the possibility of a successful electroimpedance tomography (EIT) reconstruction of the impedance distribution within the human head, taking into consideration the presence of the skull and its screening effect on electrical signals. The results of numerous computer simulations of the processes of impedance measurement and 3D EIT reconstruction are presented. The volume of the smallest recognisable perturbation within both the brain and the skull areas are determined, as well as their relationships with the required contrast. The unquestionable usefulness of the EIT approach for the purpose of impedance modelling is proven.
