Figure 6
Panel (a) shows a radiographic projection of a gold Siemens star using a 20× objective coupled to a 20 µm LuAG:Ce scintillator. The numbers indicate the thickness of individual gold lines at the given location. In panels (b) and (c) we compare two tomographic reconstructions of a polymer foam acquired with the GigaFRoST and pco.Dimax, respectively. Acquisition parameters were: pixel size = 3 µm, exposure time per projection = 0.5 ms, number of projections = 500, size of the reconstructed volume = 1008 × 1008 pixels, X-ray energy = 20 keV. |
