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

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
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.
