Micro-CT users now have the best of both worlds: non-destructive in-situ imaging and material composition information of the entire sample, inside & out

Brno, Czech Republic ―TESCAN ORSAY HOLDING a.s. announces the first and only Spectral CT analytical capability for micro-CT systems. Spectral CT provides chemical information at any point inside a sample, complementing TESCAN’s state-of-the-art structural imaging capabilities. With Spectral CT materials scientists can now see the most subtle changes in material composition and purity, and low contrast materials, such as polymers, can be differentiated from each other, which is not possible using micro-CT alone.

“Spectral CT is TESCAN’s unique, cutting-edge technology that greatly expands the capabilities of our micro-CT product portfolio,” said Dr. Wesley De Boever, product marketing manager, TESCAN. “Micro-CT provides excellent structural information, and now, using Spectral CT, our customers can understand what is in their samples, identify and differentiate chemical compounds and understand their concentration and density. It is not possible to absolutely identify chemical composition with traditional, absorption-based micro-CT.”

Spectral CT is unique in that it not only measures how many x-rays are stopped by a sample, but it also counts the individual x-ray photons. By dividing these photons based on their energy in different bins, the spectrum can be analyzed, enabling the attenuation coefficient of the sample to be precisely calculated. This allows the user to calculate densities and see contrast between different materials that are invisible using traditional micro-CT. The user can also identify unknown minerals based on k-edge imaging, remove artefacts from traditional CT scans, or calculate concentrations of different substances in a sample.

Spectral CT is an option that is available with TESCAN’s UniTOM XL, a versatile, multi-scale micro-CT system for high-throughput experiments on a diverse range of samples, and CoreTOM, for multiscale micro-CT investigations in earth sciences. It can be added to existing TESCAN UniTOM XL or CoreTOM instruments without compromising any of the system’s features. It is a complete hardware/software solution that is integrated into the micro-CT system for extreme ease-of-use, with only one click needed to switch between structural and spectral information. A full software suite features acquisition, reconstruction and analysis of spectral data.
