3D resolution evaluation. (a) Volume-rendered image of the 1 µm silica and 10 µm copper powders in a capillary. (b)–(c) Reconstructed slice images and enlarged images of copper powders. (d) Enlarged image of silica particles aggregated at the rim of a capillary. (e) Estimation of the resolution at different positions [yellow region in (b1) and (c1)] using the Fourier ring correlation method. |
