Fig. 6

Shown is the volume rendering of the 3D tomographic reconstruction of the projected objected shown in Fig. 4. A small patch is magnified in the bottom left of each image, where this patch is indicated in the top left image. A total of 180 projections are available for the reconstruction (resulting in the reconstruction shown in the top left), and the remaining reconstructions shown are from limiting the data to only 18 projections, i.e., only 10% of the original data
