Micro-CT (also known as XRM or X-Ray Microscopy) is a non-destructive 3D imaging and analysis technique, for studying the internal structure of all types of samples, with diameters from 1 mm to 20cm and full drill cores. Take virtual slices through objects and build stacks for 3D volume rendering.

Applications
Micro-CT is used in all areas of geology including:
- Porosity
- Micro-structure
- Composition
- 3D mineral distribution
- 3D analysis of shape and morphometries, including grains, sedimentary patterns, fossils, etc
- Multi-scale analysis
- Dynamic processes eg weathering, movement of fluids, crystallisation
All fields of geoscience:
- Oil and gas
- Sedimentology
- Structural geology
- Construction materials
- Geochemistry
- Paleontology
Scanning a sample with the Bruker SkyScan 2214
Select Complex Regions of Interest
ROIs are rarely regular, especially in rock samples. Bruker’s micro-CT software has powerful features for making selections and extracting the data you need.
Measure Grains Individually
With Bruker’s watershed separation algorithm, you can analyse grains and particles individually, even if they’re closely packed.
Observe Dynamic Processes
Image dynamic processes with step-by-step timelapse and in real time methods. This is known as 4D micro-CT.
Multiscale Analysis
Extract and combine information from various length scales to quantify and model the overall sample behaviour.
Complementary Technologies
The data acquired from X-Ray Microscopy adds value to other analytical techniques, including micro-XRF, XRD and optical / electron microscopy. Data can be overlaid to create 3D mineral maps and more.
