The D-bar method for the inverse problem of EIT and its application to functional pulmonary imaging

Electrical impedance tomography (EIT) is a noninvasive, non-ionizing medical imaging technique in which the conductivity of the tissue in a region of interest is computed from measurements of the current density-to-voltage mapping on the surface.  The D-bar method is a direct (non-iterative) method for solving the inverse conductivity problem of electrical impedance tomography based on complex geometrical optics solutions and inverse scattering. This talk will explain the equations of the D-bar method and its computational implementation, and will conclude with some results from pulmonary imaging of patients of Children's Hospital of Colorado with the ACE 1 EIT system at Colorado State University.
