Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability. An alternative approach has emerged with the use of CT-MRI imaging and analysis. Novel techniques extract images of the endocardial surface from CT-MRI for use in electrophysiological mapping. This surface can be used as the chamber geometry instead of reconstruction based on expensive technology measuring spatial coordinates of the catheter tip inside heart. The proposed Anatomical Template Mapping System (ATMS) will generate maps of electrophysiological parameters derived from catheter recordings without the need for proprietary equipment. The physician will direct the virtual catheter position onto the 3D model of the chamber, obviating the need for equipment to map the spatial distribution of the catheters. The major advantage is that, without the need for specialized equipment, this method of mapping is substantially cheaper and can be used with any conventional electrophysiological mapping systems. Furthermore, it will provide the most important feature of the advanced mapping systems - an understanding of the arrhythmia mechanism.Read moreRead less
A Single Digital Handheld Imaging Device For Use In Both Ophthalmology And Dentistry
Funder

Funding Amount
$431,221.00
Summary
Our aim is to produce and validate a single digital imaging device which can be used in ophthalmology (both for retinal and anterior segment imaging) and dentistry. This device will be low-cost, easy-to-operate and portable. Our planned development of the novel screening tool should help in bringing high quality, lower cost health care to those without easy access to it, firstly to residents of rural areas in Australia and then in developing countries in our region.

This device will be low-cost, easy-to-operate and portable. Our planned development of the novel screening tool should help in bringing high quality, lower cost health care to those without easy access to it, firstly to residents of rural areas in Australia and then in developing countries in our region. This can be achieved by more efficient screening methods and redirecting resources to target those with treatable eye disease only. The detection process can be progressively transferred to less expensive health workers while ophthalmologist input can be redirected to monitoring the screening results and performing surgery. The dentists travel infrequently to rural and remote WA. If the dentist can pre plan their treatment then it will be more efficient and possible to treat more people at each visit to remote and rural WA. With the help of the proposed imaging device for dentistry, the nurses and other allied personnel should be able to send the digital images in advance to dentist over Internet and therefore help dentist pre-plan their treatment. As a result, improved dental care for rural, remote and underserved communities will occur.Read moreRead less

Taking humour seriously for online safety. Harmful humour impacts on women’s wellbeing online, but is poorly managed by social media platforms, and has not been integrated into online safety regulation and policy. This project aims to bring together sociocultural theory, social media analysis, and interviews to better understand the dynamics of harmful humour online in Australia.

Harmful humour impacts on women’s wellbeing online, but is poorly managed by social media platforms, and has not been integrated into online safety regulation and policy. This project aims to bring together sociocultural theory, social media analysis, and interviews to better understand the dynamics of harmful humour online in Australia. It will work with users, community leaders and industry stakeholders to evaluate current platform and policy responses and how they could be improved. The anticipated outcomes include theoretical advances, workable principles for better content moderation processes that reduce harm without restricting healthy expression, and evidence-based contributions to debates on online safety regulation.Read moreRead less
Making Crime Pay: Manufacturing Heritage Experiences in a Digital Age. This project aims to create digital tools to allow visitors to experience Australian convict sites and historical big data in new and novel ways.

This project aims to create digital tools to allow visitors to experience Australian convict sites and historical big data in new and novel ways. The project expects to forge a synergistic long-term relationship between archives, historical sites and research programs through pioneering thematic digital storytelling techniques, allowing audiences to access research data not previously curated for public consumption. Expected outcomes include enhanced international and disciplinary collaborations, generating standards for curating digital site, archival and collection data, and new means of communicating research results to a wider public, especially descendants. This should provide significant benefits to heritage site operators. Read moreRead less
Development Of A New Surgical-guidance Tool For Intra-operative Tumour Margin Assessment In Breast Cancer
Funder
National Health and Medical Research Council
Funding Amount
$557,982.00
Summary
One third of breast cancer patients undergoing breast conserving surgery have insufficient tissue removed, resulting in an increased risk of recurrence. We have developed a high resolution optical imaging probe with the potential to detect small areas of cancer. It could be used to help guide the surgeon to remove all cancerous tissue from the patient. This grant will allow us to develop the probe to a stage that it can be used during surgery, and perform the world’s first clinical scans.

Unpacking digital temporalities in networked Vietnam. This project aims to study how digital media shape ordinary people’s lived experience of time in Vietnam. It investigates the hidden costs of promoting a digital future without accounting for stagnating structural reforms on the ground. Using ethnographic research, the project examines the lives of online petty traders, rideshare Grab bikers, tech developers, and residents in designated high-tech neighbourhoods to reveal how fast-paced digital technologies, slow-moving infrastructural change, and indelible sociocultural histories intersect. Expected outcomes include vital new knowledge of Southeast Asian digital cultures that will benefit the sustainability of Australian aid in technological development in Southeast Asia.Read moreRead less
Development Of Microscope-in-a-needle Devices For Improved Clinical Diagnostics

Funding Amount
$327,746.00
Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
Advances in positron emission tomography now allow specific pathological features of many brain diseases such as Alzheimer's disease to be measured with a brain scan during life. This Fellowship will assist Professor Rowe and his team in their world leading work on new PET scanning techniques to improve diagnosis and assist the development of treatment for Alzheimer's and other degenerative diseases of the brain.
