Electrical impedance tomography is a non-invasive, low-cost medical imaging technique that can be used long term without radiation hazards. We built a model of the torso, and then used COMSOL Multiphysics® to simulate applied current patterns, compute voltages, and find equi-potential lines. We used a filter backprojection algorithm to find the internal resistivity distribution. The results modeled sinusoidal and adjacent current patterns, and the sinusoidal pattern was found to have a better resolution than the adjacent pattern.
