Tumours could be found sooner with advance in x-ray imaging

The technique, known as phase-contrast X-ray imaging, has been developed in a five-year, EPSRC-funded project, led by University College London (UCL).

Rather than measuring the extent to which tissue or materials absorb radiation - as in conventional X-ray imaging – the technique measures the physical effect that passing through different types of tissue or material has on the speed of the X-ray itself.

The technique can also spot smaller cracks and defects in materials than conventional X-rays, as it is excellent at determining different shapes and types of matter – something conventional X-rays could only match by using prohibitively high doses of radiation.

The technique has previously been limited to large-scale synchrotron facilities such as Oxfordshire's Diamond Light Source, according to UCL’s Professor Alessandro Olivo, who led the project.

“We've now advanced this embryonic technology to make it viable for day-to-day use in medicine, security applications, industrial production lines, materials science, non-destructive testing, the archaeology and heritage sector, and a whole range of other fields,” he said.
