Figure 7.

The result of training with the machine learning network msdnet (Pelt et al., 2018 ▸; Pelt & Sethian, 2018 ▸) for short scans. (a) In the x–y direction and (b) in the y–z direction of a 6 s absorption scan of NPG. (c, d) Slices of a 36 s Zernike phase contrast scan of magnesium alloy in (c) the x–y direction and (d) the x–z direction. The noise is eliminated and the structures show great similarities to the structures observed in longer scans. For the original slice in the x–y direction, see Figs. 2 ▸ and 3 ▸, lower left.
