Approximate location of the planes with patterns of particles in the (a) the mould design for the phantom. Plane A contained a section of the inclusion whilst plane B did not. The viewpoints for the camera differed for each plane with particles. (b) Completed phantom placed on a Petri dish. Both planes of particles are visible, as well as the vertical lumen conduit and the stiffer inclusion (dashed red cylinder).
