Based on the well-known diffractiontomography (DT) method, a three-dimensional (3D) inverse scattering algorithm is proposed to identify a hidden object behind an anisotropic wall. The spatial spectral expansion of the dyadic Green's function of the multi-layered structure with anisotropic material is employed in the DT formulation of the scattered field. Born approximation is utilised for weak scatterers that model the scattered field as a linear function of the object function. The proposed method is very efficient and suitable for real-time applications due to its easy and fast implementation.

The object of this study is to estimate the viscoelastic parameters (compressional velocity and the intrinsic attenuation factor Q) of lava samples in acoustic tomography experiments by the use of an asymptotic viscoacoustic diffraction tomography method developed by Ribodetti et at 2000. 2.5-D common-offset ultrasonic experiments care performed in a water tank laboratory.
