Abstract :
Electrical impedance imaging systems apply currents to the body´s surface, measure the corresponding voltages, and use inverse methods to reconstruct the conductivity and permittivity in the interior from these data. Quick, accurate maps of these electrical parameters inside the body could improve the effectiveness of critical medical technologies
