A novel magnetic resonance imaging (MRI) technique to characterise white matter microstructure in the brain. Integrity of the cellular architecture of brain white matter (WM) is vital to normal signal conduction and is disrupted in diseases such as multiple sclerosis. Due to their characteristic molecular arrangements, WM microstructures have distinct magnetic susceptibility characteristics that can be detected with high-field and ultra high-field magnetic resonance imaging (MRI). The objective ....A novel magnetic resonance imaging (MRI) technique to characterise white matter microstructure in the brain. Integrity of the cellular architecture of brain white matter (WM) is vital to normal signal conduction and is disrupted in diseases such as multiple sclerosis. Due to their characteristic molecular arrangements, WM microstructures have distinct magnetic susceptibility characteristics that can be detected with high-field and ultra high-field magnetic resonance imaging (MRI). The objective of this project is to develop and validate a novel method of mapping susceptibility effects at high (sub-voxel) resolution with MRI. The outcomes will be a more comprehensive understanding of the relationship between changes in MRI signal and WM microarchitecture and improved susceptibility mapping that may lead to earlier diagnosis and more effective therapeutic monitoring.Read moreRead less
A hybrid magnetic resonance imaging: linear accelerator (Magnetic resonance imaging-Linac) for highly accurate radiotherapy cancer treatment. Radiotherapy is often used to treat cancer, however it is very difficult to ensure the radiation doses the tumour properly as the tumour moves during treatment due to breathing. This project will produce an image-guidance system that will allow much better targeting of the treatment and thus produce better outcomes.
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index ....Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index in turbid media, including biological tissue in vivo. We propose to apply our novel technique to study tissue calcification, a serious problem in cardiology, by making use of the refractive index contrast mechanism. Calcification of smooth muscle cells and aorta subdermal implant models will be studied aiming for prevention of calcification-associated pathologies.Read moreRead less
Modelling and characterisation of radiation beams used in radiotherapy. The purpose of this project is to use computer modelling of radiation fields in radiotherapy to investigate and improve their precision. It is expected that this will result in improved outcomes and fewer side-effects for radiotherapy patients.

Fluorescence Applications in Biotechnology and Life Sciences. The Network in Fluorescence applications in biotechnology and life sciences will coordinate a research program relating to applications of fluorescence whose proper resolution requires a high degree of interaction between biology, physics, chemistry, bioengineering and medicine.

The Network in Fluorescence applications in biotechnology and life sciences will coordinate a research program relating to applications of fluorescence whose proper resolution requires a high degree of interaction between biology, physics, chemistry, bioengineering and medicine. These would be applied to industrially relevant problems in areas such as public health, biotechnology, safety of foods, chemical biology and environmental monitoring. Approaches such as highly selective fluorescent labelling of targets using appropriate immunological and molecular techniques and purpose-engineered fluorochromes accompanied by the development of specialised instrumentation will capitalise on the multi-disciplinary research strengths in Australia and lead towards tangible industrial outcomes.
