Summary
Computed Tomography (CT) scanners produce three-dimensional images of vital organs that cannot be obtained by conventional two-dimensional (single projection) x-ray radiographs. However, the radiation exposure is hundreds of times higher than conventional radiography. We will develop the world’s first CT scanner that uses no more radiation than a single conventional x-ray image that will provide four-dimensional reconstructions of a patient’s moving internal organs.

Summary
The development of novel magnetic resonance imaging methods to investigate brain structure and function. Magnetic resonance imaging (MRI) is a non-invasive method that has revolutionised neuroscience. The goal of this project is to develop state-of-the-art MRI analysis methods that reveal new information about brain structure and function. These novel neuroimaging tools will be instrumental in furthering our understanding of how the brain works.
Advanced magnetic resonance imaging methods for the characterisation of brain structure and function. Magnetic resonance imaging (MRI) is a non-invasive method that has revolutionised the development of neuroscience and neurology. The goal of this project is to develop advanced MRI methods for the study of brain structure and function which will be applied to the investigation of epilepsy and stroke.
In-vivo detection of airway injury and disease using phase contrast X-ray velocimetry. Currently diagnosis of lung disease, a major cause of death in humans, is based on clinical symptoms that do not usually manifest until the disease is well advanced. This project will develop a novel imaging technique, X-ray velocimetry, to detect changes in tissue before symptoms arise, potentially leading to strategies for managing lung diseases.
Low dose methods for detecting early lung disease using x-ray phase contrast imaging. This project will develop a highly sensitive, low-dose x-ray imaging technique for the early detection of diseases of the respiratory system. This technology will have the potential to be used as a diagnostic screening tool to reduce the incidence of respiratory related deaths from diseases such as lung cancer and emphysema.
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
Determination of lung morphology from X-ray phase contrast radiographs. Current methods of imaging the lung rely heavily on low contrast images obtained with chest radiography or computed tomography. This research will develop new X-ray phase contrast imaging techniques capable of providing a tenfold contrast increase over conventional chest radiography at a fraction of the X-ray dose of computed tomography. Methods of extracting quantitative information on lung morphology and pathology from pha ....Determination of lung morphology from X-ray phase contrast radiographs.

This research will develop new X-ray phase contrast imaging techniques capable of providing a tenfold contrast increase over conventional chest radiography at a fraction of the X-ray dose of computed tomography. Methods of extracting quantitative information on lung morphology and pathology from phase contrast chest radiographs will be developed during this research. Eventual outcomes are likely to lead to improved methods of detecting lung disease and injury for both biomedical and clinical studies.Read moreRead less
Detection and Quantification of General Fetal Movements from Accelerometer Measurements using Nonstationary Signal Processing Techniques. There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome. This will, in turn, allow early intervention by the clinicia ....Detection and Quantification of General Fetal Movements from Accelerometer Measurements using Nonstationary Signal Processing Techniques. There are approximately 1,750 fetal deaths per year in Australian with about one-third occurring late in gestation and without an apparent cause. The development of an automated system capable of long-term monitoring of fetal health will result in accurate diagnoses and prediction of future outcome. This will, in turn, allow early intervention by the clinician to reduce fetal deaths and enhance the chances of good outcomes with resultant savings in social and financial costs to the community. The development of such equipment would spawn future research into intervention treatments and contribute to Australia's position as a world leader in computerised health monitoring systems.Read moreRead less

It will assist with health care management of PD (Parkinson's disease) patients by providing a cost-effective diagnostic tool and the possibility of predicting the clinical course of disease. This information will provide the basis for tailoring treatment to a patients needs. It is anticipated that marketing of the PD GeneChip within Australia and overseas may produce revenue of at least $40 million annually.Read moreRead less
A high throughput Grid based environment for real time bio-medical imaging. Together with Leica, we will build a virtual microscope facility that will provide substantial functionality not currently available in Australia.

Together with Leica, we will build a virtual microscope facility that will provide substantial functionality not currently available in Australia. This facility will have major national and international impact on bio-medical imaging. The software solutions and infrastructure, developed as part of this program will have considerable commercial and strategic value in their own right. One guaranteed avenue for exploitation of the software will clearly be through our industry partner, Leica. Importantly, our proposal consolidates a critical mass of expertise connecting biomedical with computer science, thereby addressing a well-recognised constraint that to date has limited their national and international impact.Read moreRead less
