Our overall objective is to significantly improve the efficacy and efficiency of image-guided neurosurgery for brain tumours by including realistic computation of brain deformations, based on a biomechanical model, in a system to improve intra-operative visualisation, navigation and monitoring. The system will create an augmented reality visualisation of the intra-operative configuration of the patient’s brain merged with high resolution pre-operative imaging data.
Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System

Funding Amount
$593,742.00
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.
Improving Global Tuberculosis Control With The AuTuMN Platform

Funding Amount
$655,059.00
Summary
Tuberculosis (TB) is the world’s leading infectious killer, with the failure of global control responsible for the vast majority of Australia’s cases. Using our robustly developed software platform, we have performed several country-level studies to predict the future burden of disease and compare the impact of alternative responses to controlling the epidemic. In this project, we will extend our platform to perform simulations at the global level and answer key questions in TB control.
Biofocussed Prostate Cancer RadioTherapy (BiRT): A Personalised Approach To Delivering The Right Dose To The Right Place
Funder

Funding Amount
$753,565.00
Summary
We propose a new approach to treating prostate cancer with radiotherapy to move from the standard whole prostate treatment to a personalised treatment that varies radiation intensity throughout the prostate. We will mathematically combine features that influence radiotherapy effect from advanced imaging, clinical and biopsy information. This model will map out the radiotherapy dose required at each part of the prostate, to maximise killing of the cancer whilst minimising harm to normal tissue
Neural Computations For Predictive Coding In Visual Cortex

$479,832.00
Summary
The project aims to use the principle of "predictive coding" - a theory that promises to be a unified theory of the brain - to understand how the visual cortex makes predictions about future events, at cellular level. This basic knowledge will not only shed light on how the cerebral cortex functions at the cellular level, but may also clarify the neuronal basis of mental conditions such as schizophrenia and autism.
Elucidating Immune Responses By Single Cell Pedigree And Tracing Analysis

Summary
To develop vaccines and to combat autoimmunity, we need to understand how initial immune activation influences the fate of immune cells and their progeny. To achieve this, we have developed microscopic techniques and analytical software with which to observe how initial signalling processes in the parent immune cell influence the death, proliferation and differentiation of its daughters, granddaughters and further progeny. We will use these approaches to determine how immune cell fate is control
Dendritic cells (DCs) are the body’s sentinels, with three specialized subtypes. They monitor for infections and cancer and then activate immune T cells to clear it. Interestingly, they can all arise from a single cell, but the precise steps are unknown. By literally filming this process and analyzing the movie, we hope to draw the ‘family trees’ that lead to their generation. This knowledge will offer crucial clues as to how to boost or reduce their numbers for medical applications.
Improved Risk Assessment For Drugs Causing Cardiac Arrhythmias

Funding Amount
$638,166.00
Summary
Fatal heart rhythm disturbances are an all too common side effect of many drugs. Tests that are in place to guard against this are effective, but widely considered too stringent, meaning the development of potentially useful new therapeutics has been hampered. This study will characterise the precise mechanisms by which drugs cause arrhythmias and identify specific patterns on patient ECGs associated with the risk of rhythm disturbances that can be used in more effective clinical testing.
Reducing The Greatest Uncertainty In Radiotherapy.
Funder
National Health and Medical Research Council
Funding Amount
$594,197.00
Summary
The weakest link in radiotherapy is defining treatment volumes (contouring). Lack of accuracy and consistency in clinical trial contouring has been shown to result in reduced patient outcomes. Manual review of contouring is resource intensive, expensive and for advanced treatments unachievable in a timely fashion. We will assess an automated approach to contouring assessment using 4 clinical trial datasets, changing practice for future studies and enabling consistent assessment in the clinic.
How Are Axons Guided To Their Targets In The Developing Nervous System?

National Health and Medical Research Council
Funding Amount
$329,644.00
Summary
Many neurodevelopmental disorders are probably the result of wiring defects. In this project we will use new technologies to study how growing nerve fibres are steered to their targets during development, and use this data to create new mathematical models which can predict which way nerve fibres should grow in different situations. This will advance our understanding of the mechanisms underlying both normal and abnormal brain development.
