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.
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.

Clinical Research Translation In Fluorescence-guided Surgery Of Brain Cancer: Developing A Surgical Endoscope With Enhanced Contrast

Funding Amount
$318,768.00
Summary
This proposal aims to improve the life expectancy of brain cancer patients by developing a new neurosurgical optical imaging device. The technology will transform the recently developed fluorescence-guided surgery procedure, where the tumour is endowed with artificial fluorescence. Our state-of-the art technology will enhance the fluorescence detection beyond visual perception to help remove hard-to-detect small cancer cell clusters, resulting in more accurate surgical removal of tumours.
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.
Non-invasive Near-infrared Optical Imaging Of Neurodegeneration

Funding Amount
$312,033.00
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.
Understanding The Roles Of Dendritic Domains In Neuronal Function

Funding Amount
$491,509.00
Summary
We aim to find cellular basis to cognitive function and dysfunction by understanding the input/output characterstics of individual neurons. Since neurons are fundamental computational units in the brain, we aim to understand how synaptic inputs to different dendritic regions are processed prompting the neuron to fire an output. We also aim to seek distinct roles of certain dendritic branches in gating sensory inputs onto the neuron.
Evaluating Coronary Stents Using High-resolution Optical Coherence Tomography Imaging In Patients With Coronary Artery Disease

Summary
A stent is a device made of metal that is placed inside an artery to prop it. Recently, the applicant introduced into Australia a novel technology to examine these stents once inside the body. This information may help make stents safer for patients
Is The Eye A Window To The Brain In Sanfilippo Syndrome?
Funder
National Health and Medical Research Council
Funding Amount
$852,967.00
Summary
Study of the retina and optic nerve permits evaluation of central nervous system – these structures contain both neurons and glia and are outgrowths of the developing brain. Therefore, eye examination may allow us to study the brain and monitor brain disease and the effect of therapy. This project will determine whether brain disease in a childhood-onset disorder (Sanfilippo syndrome) and treatment of it, can be monitored in this way.

Summary
Short-sightedness (myopia) is one of our most common eye problems, affecting approximately 20% of people. It is usually due to the eye becoming too long for its power. While we can correct short-sight with contact lenses, spectacles and more recently refractive surgery, recent evidence shows that the vision of corrected myopes is poorer than that of people who have good distance vision without the need for an optical correction. This reduction is present even when the optical minification of spe ....Short-sightedness (myopia) is one of our most common eye problems, affecting approximately 20% of people. It is usually due to the eye becoming too long for its power. While we can correct short-sight with contact lenses, spectacles and more recently refractive surgery, recent evidence shows that the vision of corrected myopes is poorer than that of people who have good distance vision without the need for an optical correction. This reduction is present even when the optical minification of spectacle lenses is taken into account (the lenses used to correct short-sightedness make objects look smaller). It is possible that the anatomical changes to the eye that occur in short-sightedness are the cause of the reduced vision. Even if the optics can be fully corrected with refractive surgery, as is now being proposed, this may not result in excellent vision. The anatomical changes may occur in different parts of the eye and depending on where they occur the nature of the visual reduction will vary. The location of the retinal changes may also be important in terms of eventual pharmacological treatments for short-sightedness. In addition, the significance of the visual reduction, in terms of its effect on the functioning of short-sighted people, e.g. ability to perform under less than optimal visual conditions such as in the presence of glare or reduced light levels, is not known. We plan to investigate this by identifying the optical and neural contributions to visual performance in short-sighted people.Read moreRead less
