Reconstruction of conductivity distribution with Acousto-electrical tomography

In this paper, a method for detecting the shape and position of object embeded in a conductive closed-domain with the acousto-electrical tomography is presented. Due to the difference of conductivity between the inclusion and the background material, we create a forward model to obtain the spatial potnetial distribution in the entire domain. Then, with the Levenberg-Marquardt algorithm the conductivity distribution is reconstructed by applying in the spatial potential distribution. A two-dimensional example is illustrated. Numerical results show that the shape and location of object in the domain can be clearly reconstructed.
