Multi-Scale X-Ray Micro-CT: New Bruker SkyScan 2211
At Analytica 2014, Bruker launched the Bruker SkyScan 2211, a new high-resolution X-ray micro-CT (computed tomography) system with the widest available range of object sizes and spatial resolutions. For the first time, a single instrument is capable of non-destructive scanning and 3D reconstruction of internal micro-structures of large objects, as well as providing sub-micron resolution for small samples.
This multiscale X-ray nanotomograph opens unique possibilities for 3D imaging and exact modeling of materials in a number of applications, including:
- Oil and gas exploration
- Composite materials
- Fuel cells
- Electronic assemblies
Scan Large Objects
The Bruker SkyScan 2211 micro-CT system can scan large objects up to 200mm in diameter, where high accuracy of <50nm for samples up to 25kg is achieved by high-precision air-bearing rotation. Combining a 600nm X-ray source with two X-ray detectors — a 3Mp flat-panel and an 11Mp cooled CCD detector — 8000 x 8000 x 2300 pixels can be reconstructed after a single scan. The smallest detectable detail (smallest pixel size) is 100nm.
Fast Image Reconstruction
The SkyScan 2211 is supplied with one of the world’s fastest commercial software algorithms for 2D/3D morphological analysis and surface/volume rendering. Hierarchical 3D reconstruction speeds up reconstruction of the object’s internal microstructure 10 to 100 times compared to traditionally used algorithms, or to GPU-accelerated reconstruction. This brings the reconstruction time for a volume of 4000 x 4000 x 2300 pixels down to just 9 minutes.
