When measurements are made in the field of electrical bioimpedance spectroscopy (EBIS), it is common to fit the raw data to the Cole model. In theory, EBIS data graphed in the impedance locus (resistance -R-on the x axis or abscissa versus reactance -Xc-on the y axis or ordinate) is expected to form an arch of a circle with its center lying below the resistance axis. The fitting process is most commonly made using least square (LS) techniques to obtain the four parameters involved in the Cole model: resistance at zero frequency (R0), resistance at infinite frequency (R∞), a time constant (τ) and a dimensionless exponent (α). In this article, the use of a geometrical approach to fit raw data to the expected arch is explored, where only three parameters are needed: the coordinates of the center in the Cartesian plane (named here as h for the abscissa, and k for the ordinate) and the length of the radius (r). These three parameters are obtained from the R and Xc values at three different frequencies. Data published in other literature was used to explain this approach, which is very simple and straightforward to use, while our own data was used to illustrate the performance of the method which, however, still needs thorough validation.
