Reconstructions of a single slice of a sample in a high-pressure diamond anvil cell which blocks 86 of the 359 projections over 180°, with 2560 detector pixels per projection. Reconstructions are computed with (a) gridrec (TomoPy), (b) and (c) SIRT with a nonnegativity constraint (ASTRA), and (d) TV-minimization using FISTA (ASTRA plugin). In (a), (c) and (d), a ring-removal pre-processing step (Münch et al., 2009BB24) was applied using TomoPy. A line profile of the center, indicated in (a) by a dotted line, is shown for each reconstruction, as well as a cropped 128×128 pixel section of the upper left part of the sample.
