(a) FE-SEM image of MnO particles (scale bar represents 1 µm). (b) Diffraction pattern at 6.504 keV. The central area including the bright field is attenuated by a factor of 0.1. (c) Absorption (upper) and phase (lower) images at 6.504 keV, 6.552 keV and 7.114 keV (scale bar represents 1 µm). (d) Horizontal (H) and vertical (V) focal intensity profiles at 6.504 keV and 7.114 keV. Gaussian fitting analysis shows that the full width at half-maximum beam sizes are 444 nm (H) by 311 nm (V) at 6.504 keV and 408 nm (H) by 280 nm (V) at 7.114 keV. (e) PRTF analysis of the reconstructed MnO particles at 6.552 keV. The full-period spatial resolution is determined to be 43.6 nm from the intersection of the 1/e threshold.
