Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System

Summary
Radiation therapy is a highly effective cancer treatment with extremely high doses delivered using very complex treatment machines. Unfortunately errors have occurred resulting in cases of patient death and mistreatment. We have developed a novel method to assess the treatment delivery in real-time to prevent errors. The method uses imaging devices that are already present on the treatment machine meaning that this method could have a major impact on patient safety in modern radiation therapy.
Beyond The Connectome: Modelling Large-scale Brain Dynamics

Summary
Several very large international efforts are currently under way that aim to map brain anatomy and activity in unprecedented detail across the lifespan. But our understanding of how complex brain activity emerges from the anatomy has lagged far behind. We will address this problem using a novel combination of state-of-the-art structural connectivity data, cutting-edge modelling, and ultrafast high-resolution recordings of brain activity.
The Clinical Impact Of Event-based Motion Correction In Paediatric PET-CT Brain Imaging

Funding Amount
$276,104.00
Summary
Movement of the head during PET-CT brain imaging can prevent accurate diagnosis by blurring and distorting the image. The problem is perhaps most acute in paediatric patients, many of whom must be anaesthetized or sedated to avoid motion. This work will establish whether a recently developed motion correction method can improve the clinical utility of PET-CT brain images in young patients, and reduce the need for sedation and anaesthesia during the PET scan.
Non-invasive Near-infrared Optical Imaging Of Neurodegeneration

Summary
Dementia currently affects over 240,000 Australians with an increasing health cost. A common cause of dementia occurs when proteins in the brain form deposits and brain cells degenerate and die. This project will develop a novel medical imaging method that will facilitate the detection of dying brain cells. This will enable a better understanding of the causes of cell death and the opportunity to identify the best time for meaningful therapeutic intervention.
Micro-elastography - A New Tool For Microscopic Intraoperative Tumour Margin Assessment In Breast Cancer

Summary
In breast cancer surgery, it is vital to completely remove the entire tumour. Unfortunately, in 30% of breast-conserving surgeries, re-excision is required because microscopic analysis after the surgery indicated some tumour had been missed. This has traumatic consequences for the patient and places a huge economic burden on the healthcare system. Using micro-elastography, we will enable the surgeon to detect small regions of tumour during the initial surgery. This probe may significantly reduce ....In breast cancer surgery, it is vital to completely remove the entire tumour.

We have previously made the most widely used animal brain atlas in the world. This atlas based on stained histological sections of the rat brain. In recent years, advances in MRI have made it possible to generate images of the rat brain at very high resolution. We have obtained a very high quality MRI image set from colleagues in Duke University in the USA, and we have begun to map these images in great detail, using our histological atlas as a guide.
Optimising Radiation Therapy Delivery For Cancer Patients Using Daily Image Guidance To Maximize Cure And Reduce Normal Tissue Side Effects

Funding Amount
$510,968.00
Summary
When using radiotherapy to kill tumours, the radiation beams need to be targeted at the tumour, plus a margin of error around it to ensure that it receives sufficient dose despite uncertainties in its exact location relative to reference points used for beam alignment. Advanced statistical modelling techniques applied to data collected from patients will be used to determine the optimal margin width for individual patients to maximise cancer cure while minimising normal tissue side effects.
Novel Nanomaterial Solutions Based On Metal And Metal Oxide For Advanced Diagnosis Of Cardiovascular Diseases

Funding Amount

Summary
Cardiovascular disease accounts of over one third of all deaths in Australia and is forecasted to become the leading cause of death in Australia and worldwide. Currently, atherosclerosis and thrombosis in coronary arteries are diagnosed by X-ray angiography, an invasive and risk-associated procedure. Our project will explore new contrast agents for the fast, reliable and safe diagnosis of cardiovascular diseases and thrombotic events, which is beneficial to many patients.
Brainstem And Hypothalamic Function And Anatomy In Migraine

Funding Amount
$652,828.00
Summary
Migraine is a disabling condition characterized by mostly unilateral throbbing head pain and a range of associated neurological symptoms. The underlying mechanisms responsible for the initiation of migraine remains unknown. We aim to determine brain anatomy and activity patterns in migraineurs throughout the migraine cycle. An understanding of the mechanisms responsible for migraine will aid in better treatment development.
EXTEND-IA Randomized Trial Of Intra-arterial Clot Retrieval In Ischemic Stroke
Funder

Funding Amount
$764,534.00
Summary
Most strokes are caused by a blocked blood vessel in the brain. Current treatments to dissolve the blockage improve recovery for many patients but often fail to unblock larger brain arteries. The EXTEND-IA trial will use advanced brain imaging to identify patients who have the most to gain if the blocked artery can be re-opened. The trial will test whether a new minimally invasive clot removal procedure performed after standard clot-dissolving treatment improves recovery after stroke.
