CSIRO’s X-factor

(CSIRO) have developed a powerful X-ray capable of giving detailed 3D images, even from inside previously opaque materials.

Until recently, X-ray technology was unable to achieve high-resolution imaging results at the microscopic level, particularly on objects with very weak X-ray absorption characteristics.

However, using powerful X-ray microscopes and experimenting with a variety of X-ray phase-contrast imaging techniques, scientists have been able to use the penetrating power of X-rays to directly image the internal microstructures of even opaque and multi-layer objects.

It is now possible to use X-rays to see inside objects such as micro-electronic components, structural materials used in aerospace, ceramics, metal foams and even minerals.

“The uses are quite varied,” said Dr Steve Wilkins from CSIRO Manufacturing & Infrastructure Technology. “We have been looking at tissue scaffolds for growing new tissue, mineral samples and micro-electronic devices for major companies.

“We are also working on the study of bone properties, aerospace materials and intergalactic cosmic dust, and there is interest from the oil exploration sector looking at the porous structure of rocks.”
