摘要

传统的Cole或CFC基本模型可能在个性化血液透析治疗中提供过于粗糙的估计。为了利用BIS仪器提供的全部信息内容，可以将传统的CFC模型扩展为更方便的模型:扩展CFC (ECFC)模型。ECFC模型用于拟合原始生物阻抗测量，以提高电阻和电抗项的整体估计精度。对CPC、ECFC模型的模拟结果与实验数据进行了对比。实验结果表明，与传统的CFC模型相比，该模型可以很容易地实现更高的精度(至少提高十倍)。

Effective bioimpedance spectroscopy method for evaluation of body cell water compartments

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