ALT Reconstructed sparse 3D Fe and Mn tomograms and a virtual slice showing the internal Fe and Mn distributions of an Arabidopsis thaliana seed. (A,B) volume rendering of the Fe and Mn tomograms reconstructed by MLEM from 20 (A) and 5 angular projections (B). The white dashed line indicates the altitude of the virtual slice shown in (C). The red line marks the altitude of the high-resolution single slice tomography shown in Fig. 3. (C) Comparison of the reconstructed results obtained by the FBP and MLEM algorithms in the function of the measured number of angular projections. The columns correspond to two different algorithms: filtered back-projection (FBP) and maximum likelihood expectation maximization (MLEM). The lines correspond to 20, 10, and 5 angular projections, respectively. (D) Comparison of the intensity profiles of Fe obtained by FBP and MLEM. The Fe intensity profiles were extracted along the white straight line indicated in (C).
ALT (a) broadband hard X-ray diffraction pattern and (b) the obtained diffraction pattern after numerical monochromatisation and the reconstructed amplitude of the sample (c, d).
