Electrical Impedance Tomography

In Electrical Impedance Tomography (EIT), a physical body is probed using electricity. Electrical currents are fed into the body using electrodes attached on the surface of the body, and the resulting voltages are measured. The aim is to produce a picture of the internal electrical conductivity distribution.

EIT has applications for example in medical imaging, where the heart or brain can be monitored for a long time without causing any pain or damage.
