This paper proposes a means of inverting impedance data to reconstruct flaws. It combines inverse scattering theory and an exact iterative algorithm via the finite element method which is incorporated to evaluate the integral kernel. This method offers the advantage of simplifying the inversion process thus extending it more easily to complicated geometries by virtue of the flexibility of the finite element method. Two-dimensional (2D) reconstruction results for a flaw in a metallic full-space as well as a surface-breaking crack demonstrate the potential of the implemented algorithm.
