Micro-Computed Tomography, a 3D Tool for Non-destructive Visualisation and Analysis
Micro-Computed Tomography (microCT) is a powerful technique to visualize the microstructure of various materials, both biological as non-biological, in a non-destructive way. By means of x-rays the internal structure is revealed on a micro- or nanometer scale. As an example this paper will focus in the study of pores and pore networks in rocks for oil exploration. The resulting dataset of a micro-CT scan is a set of thin, virtual slices through the object. 3d analysis software can extract unique numerical characteristics, such as internal porosity, size distribution for pores or grains, etc. Visualisation software shows a realistic 3D object on the screen, Micro-CT has an added value and can provide new information in 3D, leading to new insights in materials and processes.
