[The measurement frequency distribution in tissue impedance spectroscopy measurement].
In the research of tissue impedance spectroscopy measurement, the authors constructed a frequency sets that produce angularly equidistant points on the Nyquist loci. The studies of simulation data model demonstrate that, by use of the same quantity of frequency points and in comparison with the frequency sets that are logarithmic and quasi-linear, the angularly equidistant frequency sets can improve the estimate accuracy of tissue electrical model parameters of alpha and fc.
