N.B. This chapter describes works, where the calculation of the inverse solution in impedance tomography is based on the
generally used Sheffield data collection system suggested by Brown and Segar (1987).
However, subsequent research: Kauppinen, Hyttinen, & Malmivuo, 2006 has shown, that the solution of Brown and Segar is not correct.
Therefore the information given in this chapter on the measurement sensitivity distribution in impedance tomography is erroneous.
