What is Dielectric Properties of Rat Liver in Vivo: a Noninvasive Approach Using an Open-ended Coaxial Probe at Audio/radio Frequencies about?
To characterize the passive electrical properties of liver cells in vivo, we measured the frequency dependence of relative permittivity and conductivity for rat liver lobes in situ by means of a noninvasive surface probe coupled with a fast impedance analyzer, covering the frequency range 10 2 -10 8 Hz. Securing a stable contact, mechanical as well as electrochemical, between the probe and tissue surface both wetted with physiological saline, made it possible to collect a highly reproducible set of data even from lobes undergoing respiratory movement in situ. The data obtained traced a broad dielectric dispersion curve over the range 10 3 -10 8 Hz, suggestive of the involvement w of widely distributed relaxation times. As its theoretical analyses based on cell membrane models are made in a companion paper V. Raicu, T. Saibara, H. Enzan, A.
