Abstract

Electrical impedance tomography (EIT) is a non-radiative, inexpensive technique that can facilitate real-time dynamic monitoring. It has the potential to be of considerable clinical value playing an important role in diagnostics and monitoring of a number of disease conditions. EIT has been under development for over 100 years for industrial applications. Approximately 40 years ago it started to be applied to clinical problems. Some researchers tried to develop EIT as a replacement for image modality liker MRI or CT; however the really potential of EIT is its ability to monitor physiological condition related to impedance change. This is due to EITs high temporal resolution. This chapter introduces some of the basic concepts of EIT along with a number of example clinician applications, specifically, hardware, reconstruction algorithms and examples of its potential use in the brain, breast and lung.
