| Abstract | This repository includes the reconstructed TIFF-files from the following measurements:
LARGE (low-resolution) (due to filesize partioned in part I, II, III, IV and V)
1 large volume of particle mixture (50/50) of spheres (0.2 - 2 µm) and fibres (diameter: 10 µm length: 100 - 1000 µm) embedded in a matrix (wax, 15 vol-%). The large volume was extracted with an automated syringe into a small polymeric tube (diameter: 1.8 mm) and shock frozen. After that the sample was mounted on top of a needle pin and scanned with a micro-CT (ZEISS Versa510) at 80 keV, 7 W, low energy filter LE4, exposure time 2 s, optical magn. 4x, 3201 projections, 360°, Binning 2, Voxelsize 1.5 µm
SubSample - MEDIUM (medium-resolution) (SubSample 1, 2, 3)
After the scan, the LARGE volume was cutted in small disks and cutted a second time in little bars. Again, mounted on top of a needle pin and scanned with same parameters, BUT with 40x optical magnification and 25 s exposure time to go down to a system limit of 0.3 µm Voxelsize (again with ZEISS VERSA510). This was done 3 times in different heights of the LARGE volume
SubSample - HIGH (high-resolution) (SubSample 1, 2, 3)
After that, all SubSamples were scanned again with a nano-CT (ZEISS ULTRA810) at 5.4 keV, 60 s exposure time, 901 projections, 180°, Binning 1 to reach Voxelsize of 0.064 µm | |
| Additional descriptive information to understand the data | REMARK:
- 50 slices at top and bottom of the low-res and medium-res scans are distorted due to the cone-beam artefact. Typically they will be removed from the analyzed volume.
- high-resolution scans are with artefacts due to the interior scanning of the sample. Parts outside the FOV are influencing the reconstructed volume. | |
| Table of contents | - 1 LARGE scan (overall sample), split into I, II, III, IV, V
- 3 SUB-Samples medium resolution (ZEISS VERSA510)
- same 3 SUB-Samples high resolution (ZEISS ULTRA810) | |
