RadioGenes2: Modelling complex biomolecular interactions in radiated tumours: Towards understanding the genesis of therapeutic radioresistance. About 45% of bladder cancer patients require radiotherapy or surgery. Radiotherapy has a failure rate of ~50%. Surgery (bladder removal) diminishes quality of life considerably. Modelling complex gene interactions in radiated cancer cells will provide crucial knowledge on the molecular genesis of radiotherapy-resistance of tumours.

About 45% of bladder cancer patients require radiotherapy or surgery. Radiotherapy has a failure rate of ~50%. Surgery (bladder removal) diminishes quality of life considerably. Modelling complex gene interactions in radiated cancer cells will provide crucial knowledge on the molecular genesis of radiotherapy-resistance of tumours. Our findings will provide: (i) an accurate mathematical/computational model for diagnosing radiosensitivity; (ii) further insights to be applied in the pharmaceutical sector such as the discovery of novel molecular targets that have the potential to increase radiotherapy success ratios; (iii) a holistic modelling technique applicable to a larger diversity of tumours.Read moreRead less
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Automated 3-Dimensional Biomedical Registration for Whole-body Images from Combined PET/CT Scanners. This project will aid rapid assimilation of very large medical imaging datasets from different imaging devices, and will have clinical applications in diagnosis and treatment and improve patient care. The research, when extended to protein registration, will facilitate analysis of DNA and advance research in bioinformatics and biotechnology. The research could also be used for target recognition, ....Automated 3-Dimensional Biomedical Registration for Whole-body Images from Combined PET/CT Scanners. This project will aid rapid assimilation of very large medical imaging datasets from different imaging devices, and will have clinical applications in diagnosis and treatment and improve patient care. The research, when extended to protein registration, will facilitate analysis of DNA and advance research in bioinformatics and biotechnology. The research could also be used for target recognition, mosaic construction, content-based retrieval, in remote sensing and multimedia. Benefits to Australia include the provision of a readily adaptable image registration program for patient care (e.g., early detection of cancers, dementia), cutting-edge research, high-quality training for students, and encouraging international research collaboration.Read moreRead less

Fibre Optic Dosimeters for Medical and Environmental Applications. We will develop fibre optic dosimeters for environmental monitoring and radiation therapy. A novel approach using refractive index gradients will be used to capture scintillator light while rejecting noise. New knowledge will be gained of the mechanisms of radiation damage in scintillators and glasses. The small, flexible, accurate fibre optic dosimeters will be equivalent in absorbing characteristics to human tissue, making them ....Fibre Optic Dosimeters for Medical and Environmental Applications. We will develop fibre optic dosimeters for environmental monitoring and radiation therapy. A novel approach using refractive index gradients will be used to capture scintillator light while rejecting noise. New knowledge will be gained of the mechanisms of radiation damage in scintillators and glasses. The small, flexible, accurate fibre optic dosimeters will be equivalent in absorbing characteristics to human tissue, making them superior to all currently available dosimeters. Fibre optic dosimeters will enable new adaptive radiotherapy techniques and provide quality assurance of dose delivery in radiotherapy. Their multiplexing capability will lead to applications in monitoring of workplaces and aerospace environments.Read moreRead less
