Optimization of X-ray micro-tomography
for crystalline and sand rock analysis

 

 

 

3D rendering of large reconstructed volumes is carried out in the highly optimized VGStudioMax environment (Volume Graphics GmbH, Heidelberg, Germany). This program is exclusively designed for the analysis of 3D voxel data. It supports raytracing of volume data (volume rendering) that proved to be superior to simple isosurface plotting for the analysis of tomography data. The 3D plot is synchronised to 2D slices in 3 planes and support most advanced data exchange formats.

Tuning and benchmark experiments
Glass balls bulk, diameter < 80 µm
3D reconstruction frontal cross section sagital cross section
Repository like samples
Magmata rock
Smaller high density grain ~ 60 µm, fracture width ~ 40 µm


Calcite sample
Following, we present examples of 3D reconstructions and relevant cross sections for typical samples of: calcite, sand rock and magmata rock. Relevant information for the microCT measurements is also enclosed.
                                       
Calcite sample - typical fracture width 60 µm
Sand samples
                                         
Porosity characteristics; minimum detectable feature of 5 µm
Structural composition; voids, inclusions, down to 50 µm
