Electrical impedance tomography. Technical and experimental problems encountered in impedance spectroscopy in the alpha and beta dispersion regions.
The main experimental problems (temperature, electrode, polarisation, non-uniformity of electric field, non-homogeneity of biological material) of impedance measurements of biological tissue are discussed. Minimisation of the inherent sources of experimental error is proposed.
