Abstract

In Electrical Impedance Tomography (EIT), electrical signals applied to human skin are used to reconstruct the internal electrical properties of the body, resulting in an image. The mathematical reconstruction process is an extremely ill-posed inverse problem, which causes challenges in the use of EIT for medical imaging applications. The D-bar reconstruction method for EIT is a mathematical inversion process with its roots in inverse quantum scattering theory. Recent advances in D-bar methods EIT have resulted in techniques to improve image resolution via the inclusion of spatial a priori data. In this talk, we present an overview of the D-bar method along with some recent results, including EIT images and movies of human ventilation.
