Bi-layer simulations used to investigate the effect of (a) attenuation coefficient contrast and (b) layer thickness on the accuracy of various algorithms. The ★ marks the position of the boundary between layers as set by the simulation. In all scenarios, DRC with iwhTV (●) outperforms all other algorithms.
