X-ray micro-computed tomography (XμCT)
X-ray Micro-Computed Tomography (XµCT) is a form of Tomography which uses x-rays to create 3-D visualizations of a sample. This allows for a visualization of the specimen’s volumetric nature, which in turn allows for an analysis of the sample in greater detail, or the ability to quantify certain aspects of the sample.
Technique
The XµCT system is configured with a fixed X-ray source that passes a cone of X-rays through the specimen. The transmitted X-rays are then captured by an imaging detector. Projections through the sample are collected by rotating the specimen from -90° to +90°. These projected images are later combined and reconstructed using algorithms to build a 3D image of the sample.
Instrument
Xradia x-ray micro computed tomography XCT200 system
- 1µm (best resolution)
- X-ray source up to 150keV
- Rotations: -90° to +90°
- Sample dependent 2D exposure time of 1 second - 5 minutes
- Samples can be created from any material, including multiple materials provided the density of each material is not similar
