Effective bioimpedance spectroscopy method for evaluation of body cell water compartments

The traditional CFC model might offer too coarse estimations, for accurate body composition studies and for personalized haemodialytic treatment applications. To take advantage of the full information content offered by modern BIS instrumentation the traditional CFC model can be easily extended into a more convenient model: the Extended CFC (ECFC) model. The ECFC model is used to fit raw bioimpedance measurements in order to increase the overall estimation accuracy of Resistance and Reactance terms. An experimental comparison between CFC, ECFC model computer simulations, and experimental data is presented. Experimental results show that higher accuracies (at least a tenfold improvement) over the traditional CFC model can be achieved easily.
