Modeling of Electric Potentials in Human Thorax
This project investigates various electrical measurements in the body. Three-dimensional models of the human thorax are generated from magnetic resonance images. These images are segmented and all tissues are assigned a corresponding electrical resistivity. Current paths through the body may then be studied by placing electrodes in the thorax model and solving the resulting forward problem. This group’s finite difference models consist of 3.8 million elements. Applications include design of implantable pacemakers and defibrillator electrode systems, impedance cardiography, body fluid and fat measurement, and electrical impedance tomography.
