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.
Low Cost High Precision Radiotherapy: A Synergistic Framework For Tumour Tracking During Treatment

Summary
Advances in technology have enabled radiotherapy to become more sophisticated and more efficient at treating cancer. Yet, despite its sophistication, today radiotherapy suffers from a major problem: whilst we routinely image patients prior to treatment, no anatomical information is available during treatment. This project aims to solve this problem by making use of a number of sensors that are already available in a radiotherapy to track the tumours positions during treatment, when it counts.
Through this Australia Fellowship, Prof Keall and his tream will substantially improve the accuracy and effectiveness of radiation therapy for cancer by developing new techniques that will be able to ‘target’ a tumour in real-time and ‘concentrate fire’ on the most resistant and aggressive parts of it. Success in physiological targeting will create a paradigm shift in radiation therapy and could literally be a lifesaver. It’s a big challenge, but if this five-year research program succeeds, it w ....Through this Australia Fellowship, Prof Keall and his tream will substantially improve the accuracy and effectiveness of radiation therapy for cancer by developing new techniques that will be able to ‘target’ a tumour in real-time and ‘concentrate fire’ on the most resistant and aggressive parts of it.

Summary
In external beam radiotherapy highly complex radiation fields are used to deliver high doses of radiation to the tumour while sparing normal tissues. Inaccurate treatment could result in poor patient outcome or damage to normal tissues. We aim to investigate a novel imaging device to measure the dose accuracy of these fields. This work has the potential to make a significant and fundamental difference to existing verification techniques for radiotherapy treatments to ensure patient outcomes.

The recent development of the world's first prototype combined MR-PET scanner for human use has prompted immense interest. MR-PET is likely to revolutionize clinical diagnosis and basic research, by providing exquisite structural images co-registered with simultaneous functional PET images. We will exploit the as yet unexplored potential for motion information derived from the MR system to be used to correct the simultaneously acquired PET data for patient motion. This research is an excellent opportunity for Australian researchers to make important contributions to an emerging technology with high economic potential, and will strengthen Australia's international position in engineering and biomedical systems development.Read moreRead less

Advances in detector technologies have led to the development and commercialisation of small animal imaging systems such as microPET which provide high resolution images of radioactive compounds in live animals, but the images can only be interpreted qualitatively. Our aim is to develop quantitative technologies for these new imaging systems. Major outcomes will include novel methods of measuring and correcting for signal loss due to photon interactions in the body and integrated image reconstruction algorithms. This will lead to a new generation of quantitative imaging devices; the new technologies will be directly translatable to clinical imaging systems and will broaden the range of microPET applications in the life sciences.Read moreRead less
Synchrotrons, wavelet analysis and novel imaging techniques - applying physics tools to the war against breast cancer. Breast cancer leads to the second highest number of person-years of life lost due to cancer in Australia, with little known about its transport around the body.

Breast cancer leads to the second highest number of person-years of life lost due to cancer in Australia, with little known about its transport around the body. Current screening methods for breast cancer are neither 100% sensitive or specific and are heavily dependent upon expert training. This project will contribute by yielding valuable information on the transport of breast cancer and contribute to the development of an automated diagnostic method, with the possibility of its application to other diseases. The project will also involve members of the regional community, train regional scientists and provide synchrotron experience for Australian scientists in time for Australia's first synchrotron.Read moreRead less

However, the requirement for the animal to be anaesthetised precludes the study of behavioural changes in response to sensory or drug stimulus during the imaging study. In this research, we will develop novel motion tracking and computational algorithms that enable microPET to non-invasively image the brains of conscious, freely moving animals while simultaneously observing their behaviour. These new technologies will, for the first time, allow neuroscientists to study the genetic, behavioural and neurochemical correlates of brain disease.Read moreRead less
