PROBLEMS OF 3D RECONSTRUCTION AND VISUALISATION IN EIT

Abstract

In the paper different algorithms of electroimpedance tomography (EIT) are presented. The properties of EIT are discussed. Problems of proper modelling of measurement electrodes are introduced. Results obtained from developed 3D reconstruction algorithm are presented. For practical reasons the number of measurement electrodes should be increased. Measurement errors should be small, to avoid amplifying them by reconstruction algorithm. Assumed conductivity distribution for the first iteration should be as close to the real one as possible. Reconstruction time (of absolute value of conductivity) is still a problem for practical applications.
