About Our Research

Based on decades of experience, Bruker-microCT is continually improving the quality of its micro-CT instruments and methods, while at the same time creating new methods and techniques to be applied in future micro-CT scanners.


Resolution Improvements

Bruker microCT has invented a new type of X-ray emitters for high-resolution X-ray imaging and tomography in laboratory systems. Without any zone plates or other X-ray optics it allows spatial resolution down to 50nm at any place in a big or thick object. It is based on a new concept which takes into account acquisition geometry and allows a significant flux without compromising spatial resolution in the direction targeted to the X-ray detector.


Phase Contrast Tomography

A phase contrast and darkfield images often give a better contrast for studies of soft tissues biological materials or small animals as a whole compared to X-ray absorption images. Bruker-microCT developed a prototype laboratory system dedicated to biological objects and small animal studies that allows visualization and 3D reconstruction of traditional attenuation information with simultaneous extraction of phase contrast and darkfield images during a single tomographic scan. The system is based on a grating interferometer and uses a phase stepping procedure to separate phase, absorption and darkfield information for following tomographic reconstruction.

Micro-CT / NANO-CT End-Station for Synchrotrons

Bruker microCT designed, produced and installed micro-CT end-station at the Canadian Light Source (CLS) in Saskatoon. The end-station contains precision 7-axis micro-CT scanner with 11Mp cooled CCD-camera optically coupled to high-resolution single crystal scintillator on the amorphous silicon window. The system supplied with a powerful multi-computer workstation for data acquisition, processing and archiving. The system can scan objects up to 6mm in diameter using an isotropic 750nm voxel size and can reconstruct virtual slices with up to 8000x8000 pixels using GPU-accelerated reconstruction. Data archiving can be done with an internal network-attached 10...30TB disk array and a massive tape library, which is also used for scheduled software back-up by a separate server. The system is equipped with full software package including scanner control and acquisition program, GPU/CPU reconstruction program, 2D / 3D image processing and analysis package and software for visualization by surface and volume 3D rendering.

CLS - Canadian Light Source

CLS - Canada’s national synchrotron research facility - located at Saskatoon, capital of Saskatchewan region of Canada. It is the third generation synchrotron with 14 specialized beam lines available for research and scientific experiments. For details - visit CLS website: www.lightsource.ca.

The micro-CT end-station, installed at the BMIT synchrotron beam line dedicated to biomedical imaging, was designed and produced by Bruker microCT.

The installation includes micro-CT scanner with 7-axis precision manipulator and 11Mp/14bit cooled CCD camera and powerful computer set-up with control workstation, mass disk storage, tape library archive, back-up server and networking.

Acquisition pixel size can be chosen down to 750nm. The system can provide reconstruction with up to 8000x8000 pixels in every of 2600 slices after single scan. Fast volumetric reconstruction is based on GPU-accelerated reconstruction engine.
