Abstract
In this study, we test asymptotic diffraction tomography for viscoacoustic medium imaging by scaled model ultrasonic experiment. Diffraction tomography (namely, the inverse scattering problem) is a useful technique to save various classes of problems involving non destructive evaluation such as seismic exploration and ultrasonic medical imaging . Diffraction tomography is used to image the discontinuities of parameters describing the medium both in terms of localization and true amplitude of the discontinuities.
