Abstract

We present cross-sectional conductivity images of a biological tissue phantom obtained by using a 3.0 Tesla Magnetic Resonance Electrical Impedance Tomography (MREIT) system. Inside the cylindrical phantom with 140mm diameter and 140mm height, biological tissues such as bovine tongue and liver, porcine muscle, and chicken breast were placed within an agar gelatin. Injecting current of 480mArms into the tissue phantom, we measured the z-component B _z of the induced magnetic flux density B = (B_x, B _y, B_z). Using the harmonic B_z algorithm, we reconstructed cross-sectional conductivity images from the measured B _z data. Reconstructed images clearly distinguish different tissues in terms of both their shapes and conductivity values.
