Abstract

In-vivo electromagnetic field distributions of biological systems can be imaged from the measured magnetic flux density of magnetic resonance- based electrical impedance tomography (MREIT), which was induced by the externally injected current through a pair of electrodes. Since the electromagnetic field is affected by the injected current and electrical conductivity of biological tissues, the electrode type and position are important factors for determining the voltage and current density distribution. Using a three-dimensional finite element model, the current pathway and electric field distribution to optimise the electrode configurations in liver MREIT are estimated.
