A direct D-bar reconstruction algorithm is presented for reconstructing a complex conductivity from 2-D EIT data. The method is applied to simulated data and archival human chest data. Permittivity reconstructions with this new method and conductivity reconstructions with the fully nonlinear D-bar method based on [1] depicting ventilation and perfusion in the human chest are presented.
