Results from Monte Carlo simulation.

<p>(A) The actual depth (black spheres at depths of 12 and 28 mm) of the spherical inclusions can be accurately determined (grey spheres at depths of 10.9±0.6 mm 27.1±0.3 mm). (B) The depth of cylindrical inclusions can also be accurately recovered for every point in the x-y plane where they do not overlap, whereas in the overlap region the cylinder closer to the source dominates the depth assessment. The black arrow in the depth color bar indicate the actual depths of the two spheres (panel (A)) and two cylinders (panel (B)).
