X-ray technique can image nano-properties in real time

Manchester University researchers, working with colleagues in the UK, Europe and the US, claim the technique could have a wide range of applications across many disciplines, such as materials science, geology, environmental science and medical research.

‘This new imaging method – termed Pair Distribution Function-Computed Tomography – represents one of the most significant developments in X-ray micro tomography for almost 30 years,’ said Prof Robert Cernik in Manchester’s School of Materials.

‘Using this method we are able to image objects in a non-invasive manner to reveal their physical and chemical nano-properties and relate these to their distribution in three-dimensional space at the micron scale.

‘Such relationships are key to understanding the properties of materials and so could be used to look at in-situ chemical reactions, probe stress-strain gradients in manufactured components, distinguish between healthy and diseased tissue, identify minerals and oil-bearing rocks or identify illicit substances or contraband in luggage.’

The research, published in the journal Nature Communications, explains how the new imaging technique uses scattered X-rays to form a three-dimensional reconstruction of the image.
