Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer t ....Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.Read moreRead less
Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currentl ....Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.Read moreRead less
Development of a prime-boost anti-cancer vaccine. New vaccination strategies are urgently needed for a variety of diseases, including cancer. The problem with cancer vaccines is that it is difficult to trigger a response to a self protein. We propose that a prime-boost vaccination, using yellow fever virus and modified vaccinia virus ankara, could create very strong responses against tumor antigens. This approach can be patented and can revive that field of tumor vaccination, which is currently ....Development of a prime-boost anti-cancer vaccine. New vaccination strategies are urgently needed for a variety of diseases, including cancer. The problem with cancer vaccines is that it is difficult to trigger a response to a self protein. We propose that a prime-boost vaccination, using yellow fever virus and modified vaccinia virus ankara, could create very strong responses against tumor antigens. This approach can be patented and can revive that field of tumor vaccination, which is currently restrained by the difficulty of breaking immunological tolerance. We envisage the construction of a anti-cancer vaccine vector with obvious market potential. An exciting prospect is that this approach could be used as a prophylactic vaccine and possibly also as a therapeutic vaccine.Read moreRead less
Techniques for probing biological media with holographic angular scattering spectroscopy. Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples. If depth selectivity can be added, we could perform non-invasive measurements on animals, making a huge re ....Techniques for probing biological media with holographic angular scattering spectroscopy. Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples. If depth selectivity can be added, we could perform non-invasive measurements on animals, making a huge reduction in their usage. We could assess thick tissues enabling early noninvasive diagnosis of malignancy in tumours in situ or muscle characterization for meat quality or muscular dystrophy. These benefits impact on research, animal ethics, and on health, and have commercial potential in life and medical sciences, and the meat industry.Read moreRead less

This project brings together an international, multi-disciplinary team to develop innovative, high-resolution techniques to identify diseased tissue. Success will result in a new medical imaging technique allowing clinicians to quantify the mechanical properties of tissue, effectively creating a high-resolution image of what the tissue 'feels' like. This may help them to more accurately identify cancerous tissue during surgery and reduce rates of recurrence. It could aid in tissue engineering and regeneration and will provide a new database of tissue mechanical properties. The project will position Australia as a leader in this newly developing medical imaging technology, with significant potential for commercialisation.Read moreRead less
