NanoXCT Project Description

Within the past decades, advances in miniaturization from micro to nano-scale have had dramatic impacts on our lives. Consumer electronics, which once occupied large volumes, now fit in the palm of a hand. But nanotechnology does not only improve in electronics. Also material sciences, chemical engineering, or biology are strongly profiting from nanotechnology. The tremendous achievements in all of these areas would not have been possible without the material analytics in behind. Material analytics for nano-scale characterization currently covers destructive methods, surface inspection methods, or 2D methods.
To date it is not possible to get a comprehensive representation of a specimen including internal and external 3D-structure analysis as well as a chemical analysis without destroying the probe. In this respect, nano-scale material analytics is currently on the edge of a new era, which is targeted in the NanoXCT project. The project addresses the limitations of conventional techniques using 3D X-ray computed tomography, which allows for a non-destructive and fully three dimensional characterizations of specimens. In order to facilitate X-ray computed tomography at the nanometer scale, NanoXCT comprises a novel concept of an ultra-bright X-ray source in combination with a high precision focusing and emission system. Furthermore, a highly sensitive, photon counting wide field of view small pitch X-ray detector concept will be included. The concept is perfected by a high precision manipulation system, which allows for alternative scanning geometries as helical CT, and a suitable software environment for data processing and analysis.
NanoXCT links the activities of 10 partners from 7 European countries to design, develop and implement a compact X-ray computed tomography system for non-destructive characterization of nano materials and components.

Topic Description

Together with our company and research partners you will work on the creating and implementing the NanoXCT software demonstrator. This demonstrator will be based on an existing commercial visualization framework, which will be adapted and extended for NanoXCT. The methods and techniques to be developed for analysis and visualization of the NanoXCT data are found in the following domains (which your topic will also come from).

Multi-modal Data Visualization

For multi-modal data visualization the software demonstrator will merge in the same display frame the data generated by XCT for structural analysis, the information calculated by multi energy XCT and the data generated by XRF for chemical analysis. Elemental information will be color-coded in the renderings. Furthermore individual concepts, e.g. magic lenses for XRF data, grey value profiles as well as blending techniques will be used for visualization.
