Abstract
Via a simple algorithm given by the Born approximation one can reconstruct a tomographic image of the sound speed of an acoustically penetrable body, knowing its scattered sound field. This method is based on the hypothesis of weak contrast between the body and the external medium. Otherwise the image is a distorted version of the object. The distortion is characterised analytically. Thus we propose a modified algorithm that cancels the image defects so as to obtain a fast and reliable reconstruction method.
