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
Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobili ....Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobility of water molecules is a potent indicator of the microscopic structure of the cartilage scaffold. We will use this fundamental biophysical relationship to measure the internal architecture of collagen fibres; observe the changes effected by mechanical load; and distinguish between healthy and osteoarthritic cartilage.

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.
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

Medical Device technologies embrace a wide range of scientific, engineering and medical knowledge, with the goal of assisting a clinical professional (doctor or nurse) deliver a service to a patient in an efficacious, cost effective manner. Development of appropriate medical devices, whether for diagnosis, treatment or prevention of disease or disability, is critical to improving health care and reducing health care costs. To be successful, a device must include all relevant disciplines in the research, development and testing phases. This network will bring together these groups, promoting knowledge sharing and cross-disciplinary investigations that illuminate current device limitations and potential solutions.Read moreRead less

Part B: Slice Correction Due to Non-linear Gradient Fields. The primary aims of this project are to contribute to the new generation of MRI methodologies through technical innovation, with particular emphasis on NMR imaging under inhomogeneous magnetic fields. The new techniques will be of enormous benefit for superconducting magnet design, reducing material usage, and eliminating the need for the expensive post-production shimming process. The entailed project is extremely challenging, while preliminary calculations presented in this application show some progress towards demonstration of feasibility. The program is an ambitious one with a full R&D program over 3 years, which will provide leadership, and to both foster and focus research interest in Australian engineering and scientific endeavors in the field of Magnetic Resonance technology.Read moreRead less

This research is important to the whole Australian community as it will lead to improved equipment for measuring optics of the eye and their effects on spatial vision, better techniques for measuring vision, and obtaining a better understanding of the contribution of the optics to human vision. It will provide information about how correcting optical defects through customized refractive surgery and how inducing optical defects (eg with progressive addition lenses) affect vision, and will thus guide developments in refractive surgery and spectacle lenses.

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.
