Figure 4
Left: phase-contrast computed tomography reconstruction of the specimen (red). Middle: isosurface plot of the DT volume, where the colormap applied to the isosurface represents spatial distances between the CT and DT isosurfaces. Right: zoomed-in detail, near the central hole of the specimen, of the DT reconstruction with different numbers of analyzers crystals. In all panels, CT images are red and DT − CT difference maps are in blue. |
