The 3D Imaging Center collaborates with commercial consortiums on x-ray based technology. We have contributed to the development of both x-ray based instruments, methods and algorithms. 

Through experience of X-ray imaging in a broad range of applications, we can lead the effective development of new technology. We have access to versatile instruments that accelerate the developments and enables proof of principle measurements. 

Much of the projects stems from exploratory work on energy dispersive X-ray detectors.

Examples of innovation projects

Airport scanner

An enhanced Airport scanner for Secure checkpoints in collaboration with Exruptive ( and Detection Technology ( )

We help develop a scanning solution that take full advantage of novel energy dispersive detectors for a more accurate threat detection. At the same time the scanner provide an efficient 3D reconstruction of the luggage even as the cross section is increased due to the innovative trolley solution.

The solution is now being marketed for Airports globally. 

Scanner for in-line detection

A scanner for in-line detection of flaws in the production of composite polymers for e.g. space applications. The project is in collaboration with Space Composite Structures Denmark ( and Radalytica (  

We combine the flexibility of a multi-axis robotic scanner with the contrast enhancing capability of energy resolving detectors and phase imaging provide manufacturers of high performance components with information about the product as it is being made.  We can furthermore extract the scatter signal to reconstruct information about voids and cracks below the conventional resolution limit of a radiographic scanner. 

System for diffraction-based imaging

A laboratory system for diffraction-based imaging in collaboration with Xnovo ( and Advacam (
We have increased the accuracy and resolution of single photon counting planar detector for use in a computational phase retrieval algorithm. The method depends heavily on precise knowledge of spatial and spectral information of the instrument components.  The technique is currently being developed as an add-on capability for commercial CT instruments.

An X-ray based system for fibre reinforced materials in collaboration with Xnovotech and PSI ( This technique takes advantage of the intrinsic photon interactions to obtain sensitivity to resolve structures in the materials. We are pushing the technique from use in synchrotrons to be an effective and robust technique in laboratory-based scanners. The technique is still being developed but will have huge impact for composite production of high-performance components in all industries.
