Medical impedance tomography and process impedance tomography: a brief review

The resurgence of research into medical electrical impedance tomography about 20 years ago was soon accompanied by a parallel development in process impedance tomography. The interaction between these two research communities was beneficial to both groups. In recent years this interaction has been very much reduced. This paper briefly reviews the history and then the current developments in medical impedance tomography.
