In recent years, advances in D-bar reconstruction methods for 2D EIT have resulted in a priori methods, wherein prior spatial information is included in the D-bar equations. These methods have been demonstrated to produce improved spatial resolution in reconstructions of computer-simulated EIT data. In this talk, we present the first human data reconstructions computed using a priori D-bar techniques, including still and moving images of human tidal breathing and a comparison with standard D-bar reconstructions.
