We propose a new EIT image reconstruction algorithm using multiple boundary voltage data from a planar array of voltage-sensing electrodes. The current injection electrodes are placed so that the induced internal currents approximately flow in the direction parallel to the surface of the voltage-sensing probe. The proposed algorithm uses the interrelationship between the measured voltage differences and the computed current, which allows us to derive a PDE-based Ohms law. Based on the derived voltage-current relation, we produce images of conductivity changes within a local region underneath the voltage-sensing probe. We describe the new image reconstruction algorithm and its numerical simulation results.
