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. 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.

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
Understanding surface acoustic wave atomisation for pulmonary delivery of drug aerosols in personalised medicine. Delivering drugs via the lung is hampered by development costs and inadequate technology. This project will provide an understanding of atomisation in our unique respire system, enabling not only the delivery of new vaccines and drugs but also the rapid and cost effective development of new disease treatments personalised to the patient.
Acoustic trapping for life science applications. Force fields can be established to move suspended cells into predefined locations using high frequency vibration; randomly dispersed cells can be brought together into clusters. This project aims to develop such technologies and will have applications in drug discovery and cell to cell interaction studies and has the future potential to promote the health of Australians.

Summary
Miniaturised fibre-optic probes for biomedical image and sensor data fusion. The project aims to develop new types of tiny biomedical imaging devices based on optical fibres that can be inserted into the body via hypodermic needles or catheters. These devices will have the ability to generate a three-dimensional image of the tissue region. As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. ....Miniaturised fibre-optic probes for biomedical image and sensor data fusion. The project aims to develop new types of tiny biomedical imaging devices based on optical fibres that can be inserted into the body via hypodermic needles or catheters. These devices will have the ability to generate a three-dimensional image of the tissue region. As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. These minimally invasive devices will produce information-rich multidimensional fused image and sensor data, opening up new possibilities for biologists and medical researchers to study disease progression and treatment in living animals and humans, with great potential for scientific discovery.Read moreRead less
Towards direct imaging of neuronal currents with MRI. This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. 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.

This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. 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. An integrated framework for simulating nc-MRI in the visual cortex is expected to be developed.Read moreRead less
Combined optical and electrical stimulation of auditory neurons. The bionic ear, which has now helped to improve the hearing of over 200,000 people worldwide, is a great example of Australian innovation success. This project aims to develop the fundamental technology that will underpin the next generation of these devices using a combination of infrared light and electrical signals to stimulate auditory nerves.
Novel imaging technologies for continuous measurement of tracer kinetics in awake animals. The fates of biologically relevant molecules, such as proteins and antibodies, in the body are fundamentally important for understanding the mechanisms and treatment of disease. This project will enable for the first time continuous imaging of the location and time course of labelled molecules in conscious, freely moving animals.
Next generation positron imaging technologies for contemporaneous measurements of brain function and behaviour in freely moving mice. The mouse brain is an important target for Post Emission Tomography (PET) imaging studies that aim to elucidate the role of specific molecular pathways in determining normal and aberrant brain function. However, current imaging technology requires the animal to be unconscious which precludes the study of pathways involved in cognition, learning and behaviour.

The mouse brain is an important target for Post Emission Tomography (PET) imaging studies that aim to elucidate the role of specific molecular pathways in determining normal and aberrant brain function. However, current imaging technology requires the animal to be unconscious which precludes the study of pathways involved in cognition, learning and behaviour. To overcome this major limitation this project will: investigate tomograph designs capable of continuously imaging a moving animal; develop a PET detector with sub-millimetre spatial resolution and depth-of-interaction capability; and, develop a fully integrated motion tracking system. This research will lead to next generation PET technologies for contemporaneous brain imaging and behavioural analysis in freely moving mice.Read moreRead less
