In a realistic 3D imaging configuration that is based upon an existing small animal imaging system, the far-field-based algorithm exhibited a better resolution than the point-like-transducer-based algorithm did. (a) The original phantom in the z = 0 plane. The reconstruction results for (b) the point-like transducer approximation, and (c) the far-field approximation, respectively.
