R. Sikora et al., The bell function approximation of material coefficients distribution in the electrical impedance tomography, IEEE MAGNET, 36(4), 2000, pp. 1023-1026
New linear approximation of conductivity distribution inside the body using
the bell functions approximation is presented in the paper. In order to so
lve the Inverse Problem the objective function with the hell function param
eters have been introduced. Theory was confirmed by results obtained from t
he real Electrical Impedance Tomography (EIT) measuring system.
