Figure 1 - Schematic drawing showing the multiview oblique incidence technique of tomosynthesis. The X-ray view illustrated shows the projection of a discontinuity onto the detector plane. The X-ray images acquired at each position have the discontinuity projected to a different location on the detector plate.

Figure 2 - Horizontal views at two different levels within the assembled plate object: (a) horizontal X-ray image through the bottom plate (at 10 mm [0.4 in.]) of the 25 mm (1 in.) thick aluminum plate assembly, showing only the holes in the lower plate; (b) horizontal X-ray image at 15 mm (0.6 in.), showing the two holes in the upper plate.
Figure 3 - A horizontal X-ray image at the interface of the two aluminum plates, showing the Z configuration line for reconstruction of a vertical view through the thickness of the assembly.
