Development of new methods to measure in vivo properties of human body tissues. This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo.

These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo. These techniques may be useful in diagnosing soft tissue disease or injury which are currently difficult to detect using standard imaging techniques. It will also explain how the muscle-tendon unit moves during normal motion in live humans.Read moreRead less
Novel methods for detecting changes in soft tissue microstructure and biomechanical properties using multi-modality MR imaging. This project will lead to novel methods for studying the internal structure of the soft tissues of the body, such as muscles and brain tissue, and how this is affected by mechanical loading and disease states. The project will thoroughly validate these new methods. This will not only provide new techniques for research use, but lead to improved diagnostic techniques in ....Novel methods for detecting changes in soft tissue microstructure and biomechanical properties using multi-modality MR imaging.

Quantitative multi-modal optical imaging of deep tissue. This project aims to create new tools to quantify the structural and functional properties of tissue. Combining multiple optical imaging technologies (multi-modal) into a single, miniaturised probe, these tools could enable physiologists and biomedical researchers to obtain new insight into disease. Encasing the highly miniaturised probe within a medical needle is aimed to allow insertion of the 'needle probe' deep into tissue, extending o ....Quantitative multi-modal optical imaging of deep tissue.

Encasing the highly miniaturised probe within a medical needle is aimed to allow insertion of the 'needle probe' deep into tissue, extending optical imaging to areas not previously accessible. The project could develop novel quantification models to allow longitudinal assessment and comparison between subjects. Validating the tools with specific biomarkers, it could provide outcomes in breast and liver cancer, and a framework to explore other diseases.Read moreRead less
Quantifying cortical thickness and white matter hyperintensity volumes and determining their relationship on Magnetic Resonance Imaging in ageing brains. Australia's population is ageing, with a significant projected increase in the number of people aged over 65 and 85. Mental health and quality of life for this ageing population have become an increasingly important issue. This project directly addresses the National Research Priority 2 in the terms of ageing well, ageing productively.

Australia's population is ageing, with a significant projected increase in the number of people aged over 65 and 85. Mental health and quality of life for this ageing population have become an increasingly important issue. This project directly addresses the National Research Priority 2 in the terms of ageing well, ageing productively. Accurately measuring the distribution of brain structural changes is an effective way of differentiating normal ageing from various pathological conditions reflecting the underlying pathology. The project has access to an unprecedented large sample of longitudinal Magnetic Resonance Imaging and health/clinical data and will produce a set of algorithms to examine this issue and put Australia at the forefront of such research.Read moreRead less
Haemodynamic investigation of flow diverter stents for the treatment of intracranial aneurysms. This project will explore the engineering of a flow diverter, an endovascular device for the treatment of brain aneurysms. The project will determine the optimal design of new types of flow diverters, which in turn could improve the effectiveness of treatments, thus reducing the associated costs of cerebral haemorrhage and stroke.
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.
Development of electrical probes and advanced classification algorithms for early detection of cancer. The curable precursor of cervical cancer is cervical intra-epithelial neoplasia (CIN). Various cancer probes will be constructed for the identification of CIN based on electrical measurements on tissue. Through studies of the cellular structure and the junction between cells, a theoretical model of the electrode/mucus/tissue system will be developed at and below the surface of the tissue under ....Development of electrical probes and advanced classification algorithms for early detection of cancer.

Various cancer probes will be constructed for the identification of CIN based on electrical measurements on tissue. Through studies of the cellular structure and the junction between cells, a theoretical model of the electrode/mucus/tissue system will be developed at and below the surface of the tissue under examination. Theoretical modelling, probe development and detection algorithms will be used to identify CIN in real-time with concurrently high sensitivity and specificity. Effective electrical probes for early detection of cancer (cervical, lung and breast) will be of enormous national and international benefit.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
