A phantom structure was reconstructed using single, double and conical tilt geometries to assess the quality of the tomograms with regard to anisotropic deformations of the volume. The phantom was comprised of 256 analytically constructed “knots”, randomly oriented and displaced in the slab. An individual knots is shown at the bottom left corner.
