Model-based estimation methods for improved classification of electroencephalographic data: application to monitoring depth of anaesthesia. This project will use advanced computing methods applied to electrical brain wave recordings to track how the brain changes as a person undergoes general anaesthesia during surgery. This will lead to better anaesthesia monitoring devices and reduce the chances of people experiencing pain during surgery or IQ deficits after the anaesthesia.
Portable three-dimensional ultra-low field MRI. This project aims to address low signal-to-noise ratio in ultra-low-field (ULF) MRI, using dynamic, mechanically-operated small permanent magnet arrays to generate magnetic fields needed for pre-polarisation and spatial encoding. Superconducting magnets make conventional MRI scanners too heavy and expensive for much of the world’s population. ULF MRI instruments offer image contrast mechanisms, are less costly and potentially portable, so can be us ....Portable three-dimensional ultra-low field MRI. This project aims to address low signal-to-noise ratio in ultra-low-field (ULF) MRI, using dynamic, mechanically-operated small permanent magnet arrays to generate magnetic fields needed for pre-polarisation and spatial encoding. Superconducting magnets make conventional MRI scanners too heavy and expensive for much of the world’s population. ULF MRI instruments offer image contrast mechanisms, are less costly and potentially portable, so can be used in unconventional situations. This project will design, construct and evaluate an instrument capable of three-dimensional 3D ULF-MRI. This technology is expected to be useable in field hospitals and emergency settings, and to benefit fields including magnetic refrigeration and remote sensing.Read moreRead less
Chip-scale implantable bionics for next generation therapeutic neural prostheses. Australia has an unmatched reputation as a world leader in neuroprostheses.

Australia has an unmatched reputation as a world leader in neuroprostheses. Most notable of these is the bionic ear and, more recently, leading edge research towards a bionic eye. This project will combine the research strengths and experiences from both the hearing and visual bionics fields to address the main obstacles that prevent the number of electrical stimulation channels (equating to the number of frequencies heard by the deaf, and the number of spots of light seen by the blind) from increasing. The study will improve our understanding of the electrode-tissue interface, the life-long implantablity, and electrical circuitry that will allow future bionic devices to significantly improve their performance.Read moreRead less

Rotating Radiofrequency Phased-array for 7 Tesla Magnetic Resonance Imaging. This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications.

This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequency coils, an essential component of MRI systems, can distort images and induce potentially harmful tissue heating. The aim is to design and develop a rotating multi-channel radiofrequency coil array, with dedicated image reconstruction software, to overcome these limitations. This would facilitate detailed images that can be obtained quickly and safely.Read moreRead less

Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity. Signal-to-noise ratio is at the limits of detectability using current imaging systems and nc-MRI is yet to be convincingly demonstrated.
