Microtomography
TECHNICAL SHEET
General description
Micro-computed tomography (Micro-CT) is a non-destructive 3-D imaging technique that allows to see inside an object by means of X-rays. The pixel sizes of the cross-sections are in the micron-range, while the scanned object size can be up to 2 cm in diameter.
A Micro-CT scanner records X-rays transmitted through a sample as a two-dimensional projection image. The repetition of this imaging over the full rotation of the sample of 180°C leads to a series of projections that can be reconstructed into a full cross-sectional view of the sample (or slice). These slices can further be processed into three-dimensional models, revealing a volumetric information on the internal features of the sample.

Reporting
A standard scan will take place over a 2-h duration. Projection images will be recorded for a full 180° rotation of the sample and processed into reconstructed slices.
Advanced image processing such as segmentation, filtering, calculation of parameters such as pore sizes and volume and 3-D reconstruction is of course also possible and scan durations can be adapted according to the sample and information requirements.
A standard report will provide the raw images as well as the reconstructions and a short accompanying text.
Practical Information
Measurements can be carried out on objects with sizes up to 2 cm by side.
Measurements are carried out on a Bruker Skyscan 1172G operating at max. 100 kV. The minimum pixel size is 2-27 µm.
