A finite difference scheme is introduced to solve the D-bar equation. The D-bar equation arises in electrical impedance tomography (EIT) when using the complex geometrical optics solutions to recover the conductivity within a body. This scheme is second-order and is first used on a test equation for error analysis and then used to reconstruct EIT images using the D-bar method.
