Electrical Impedance Tomography Image Reconstruction for Adjacent and Opposite Strategy using FEMM and EIDORS Simulation Models

Electrical Impedance Tomography is a low resolution, fast and low-cost, medical imaging technique, which is increasingly catching up both in research and application fields. The main concept includes the usage of electrodes to insert current and measure voltages from the object examined in order to reconstruct the conductivity map of its interior. There are many options to achieve that and the number of the electrodes plays an important role. In this paper, simulation models were generated using the FEMM software tool along with MATLAB to characterize the imaging quality results achieved with respect to the measuring strategy and the electrodes' number.
