This project aims to achieve safer, faster, and cheaper 3D X-ray imaging through a technique known as ghost imaging. X-ray imaging provides valuable information about internal structures, however, X-rays are carcinogenic and exposure (or dose) should be limited. Ghost imaging is an unconventional technique developed with visible light that has many potential benefits over conventional imaging. This research group are world leaders in ghost imaging and expect to develop software and hardware techniques to realise its potential and extend it to ghost tomography. The focus of this project is on reducing cancer risk in medical imaging, and allowing real-time quality control for 3D printing in safety-critical industries such as aerospace.Read moreRead less
Electron Tomography of Electromagnetic Fields, Potentials and Sources. The proliferation of technologies incorporating magnetic materials with exquisitely fine structure demands precise characterization methods, which are able to keep pace with magnetic miniaturization.

The proliferation of technologies incorporating magnetic materials with exquisitely fine structure demands precise characterization methods, which are able to keep pace with magnetic miniaturization. However, existing techniques are unable to directly image magnetic materials at high resolution in three dimensions. We will overcome this deficiency, by combining an exciting new methodology for the three-dimensional visualisation of electromagnetic fields, with the latest cutting-edge electron-microscopes, thereby facilitating advances in magnetic nano-manufacturing. The anticipated applications are vast, from patterned nanomagnets and magnetic proteins, through to semiconductors and superconductors.Read moreRead less
Development of Novel Two-dimensional Techniques for Magnetic Resonance In-vivo Spectroscopy. Body chemistry alters with functionality, pain, ageing and disease. These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis. This is curre ....Development of Novel Two-dimensional Techniques for Magnetic Resonance In-vivo Spectroscopy. Body chemistry alters with functionality, pain, ageing and disease. These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis. This is currently hampered by our inability to separate the composite resonances in a one dimensional MR spectrum. Research will allow two dimensional MRS to be implemented and provide detailed chemical information on human organs in vivo. Read moreRead less
