A technique is described for the inversion of elastic scattering data in order to extract the geometrical properties of a scatterer embedded in a solid. The technique is in part based on the Kirchhoff approximation. Results are presented for the inversion of theoretical and experimental scattering data for a variety of shapes including spherical, ellipsoidal, and disc-shaped voids as well as a compound void consisting of two overlapping spherical voids of different radii.
