B. Rigaud et al., IN-VITRO TISSUE CHARACTERIZATION AND MODELING USING ELECTRICAL-IMPEDANCE MEASUREMENTS IN THE 100 HZ-10 MHZ FREQUENCY-RANGE, Physiological measurement, 16, 1995, pp. 15-28
In vitro electrical impedance spectrometry was performed on tissue sam
ples excised from sheep. Measured data have been processed to reduce d
ispersion in measurements and to provide criteria useful for tissue co
mparison. Two electrical models are proposed for tissues exhibiting a
one-circle impedance locus and a two-circle impedance locus. Measureme
nt results and electrical parameters of tissues and models fitted to e
xperimental data are presented. Model sensitivity to parameter variati
ons is discussed.
