We have developed an inverse scattering technique for removing the blurring of pulse-echo thermal wave images. Preliminary results have been presented elsewhere [1-5]. We have extended the method to include thermally anisotropic materials and also multiple scattering effects. The method provides an algorithm for inverting a single image, and obtains the shape of the scatterer with a single calculation. The method involves no tomographic reconstruction and does not rely on a successive approximation scheme.
