Abstract :
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 al. (2000). 2.5-D common-offset ultrasonic experiments are performed in a water tank laboratory
