Figure 9
(a) Profiles from image simulations using the Fresnel–Kirchhoff formula for a 1.2 mm-diameter nylon cylinder and 25.52 keV X-rays. The curves correspond to different widths of the PSF. (b) CT-number profiles through a reconstructed xz slice from image simulations using the Fresnel–Kirchhoff formula for a 1.2 mm-diameter nylon cylinder and 25.52 keV X-rays. The curves correspond to different widths of the PSF. The insert graph shows expanded detail at one cylinder edge for the Mσ_sys = 40 µm curve (`pb' denotes parallel-beam reconstruction) plus the curve for cone-beam reconstruction (`cb'), and the corresponding curves with inclusion of a phase-retrieval processing step (`pb & pr' and `cb & pr', respectively). Further details are provided in the text.
