Abstract

This paper introduces a new method for a short-time measurement of bio-impedance in a cross section of local tissue. Validity concerning a new configuration for the electrode and the measurement method has already been done using three-dimension numerical analysis as reported in a previous paper. In this paper, we focus on living tissues represented by an equivalent circuit model. A model in the cross section of the tissue can be substituted for a distribution equivalent circuit, and the parameter of impedance is estimated using the Gauss-Newton method. Simulation results show that the parameter for contact impedance, fat, mammary, muscle and tumor layers can be estimated with an error of less than 0.01%.
