ANBUG-ANSTO Town Hall events, lecutre on Neutron Imaging, presented by Dr Joseph Bevitt from the ACNS.

This lecture aims to provide an introduction to the principles of radiography and tomography, and celebrate 10 years of “Dingo” and neutron tomography collaborations at ANSTO.
Radiography and tomography (CT) are critical tools that traditionally employ the use of X-rays to reveal and evaluate 3-D internal and surface renderings in medicine, engineering, geology, palaeontology and cultural heritage. In many circumstance, X-rays fail to adequately penetrate through samples, and/or yield poor internal contrast. In these cases, Dingo and thermal-neutrons often provide complementary, or superior contrast alternative to X-rays, due to their different material interactions.
In palaeontology, Dingo has achieved unpreceded contrast and detailed-reconstructions of previously inaccessible fossilised soft tissues and stomach contents. In engineering, neutrons are being used to investigate porosity and mechanical properties of 3D-printed engine components and aerospace carbon-fibre composites. Dingo is being used to answer long-standing curatorial and conservation questions in cultural heritage, reveal hidden texts in ancient scrolls and investigate dental surgery in Ancient Egypt. It is increasingly being used for the evaluation of neutron capture therapy agents, and the instrument’s capabilities are being pushed toward high-throughput applications.
This presentation will use examples from recent and high profile studies to provide an overview of neutron imaging in Australia, directions for future research and the exciting opportunities for neutron imaging in Australia.
