Electrical Impedance Tomography (EIT) is a method for imaging the internal conductivity
distribution of a cross section of human body using known injected currents and measured
potentials on the surface. The problem of recovering the internal conductivity from this data is
extremely ill-conditioned and, by contrast to many other medical imaging techniques, nonlinear.
Inevitably EIT images will be low in spatial resolution but the technique promises high
temporal resolution, continuous monitoring, relatively low cost and the possibility that soft
tissue changes may be imaged which are invisible to other imaging techniques
