Abstract
Abstract—We need to know a complex conductivity spectrum of an imaging object to interpret reconstructed difference images in Electrical Impedance Tomography (EIT). Using a Bio-Impedance Spectroscopy (BIS) system, we measured complex conductivities of seven different materials including TX151, polyacrylamide, animal hide gelatin, agar, saline, cucumber and banana. Obtaining time- and frequency-difference images of a saline phantom containing a banana or TX151 object, we could correlate the images with measured complex conductivity spectra. We propose further imaging studies using different materials of known complex conductivity spectra to properly calibrate time- and frequency-difference images in EIT.
