Summary
Microbeam Radiation Therapy (MRT) is an emerging X-ray radiosurgery modality that offers new hope for the treatment of brain cancer and other human brain diseases. A tissue equivalent radiation dosimetry system is essential for upcoming MRT human trials to precisely verify treatment plans. We are recognized world leaders in real-time silicon detector instrumentation for radiation dosimetry. We plan to develop and demonstrate X-RATE, the X-ray Real-time Active Tissue Equivalent dosimeter.

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.

Summary
Over 50% of cancer patients receive radiotherapy (RT). Tumour control using RT is limited by adverse normal tissue reactions. Unlike conventional RT machines, the Australian synchrotron has the capability to deliver strong radiation in very thin slices, termed microbeam RT (MRT). Tumour control has been obtained in animal models with a remarkable sparing of normal tissue using MRT. We will optimize MRT as a crucial step towards a potentially revolutionary cancer treatment.

Summary
Radiotherapy remains an important non-surgical treatment for over 50 % of cancer patients. This project aims to develop methods that will enable the optimisation of the patients' treatment as it progresses by non-invasively measuring the radiation dose delivered each day. This will increase the likelihood of curing the patient as well as reducing the side effects experienced due to the treatment. This will improve the patients' quality of life post-treatment.

Summary
For pelvic cancer patients too much radiation causes rectal problems which are hard to avoid. To reduce the problem we have developed a tiny dosimeter, which we will network to measure the radiation in the rectum as it is being received. This will tell us the maximum safe dose of radiation we can give before causing rectal complications. This will be an effective quality assurance and radiation safety tool.

Summary
Irregular breathing causes anatomical errors in medical images and consequently cancer targeting accuracy, resulting in poorer clinical outcomes and increased health care costs. We have developed and patented the Breathe Well Audio Visual (AV) biofeedback device, to improve breathing regularity. Our goal is to gather critical scientific information and reach commercial proof-of-concept objectives that will allow us to attract investment to establish a viable medical device enterprise.

The prognosis for someone diagnosed with cancer is much better than commonly believed. If detected early, malignant tumours are generally well localised. During these early stages of tumour growth high doses of radiation therapy can with a high probability, eradicate a cancer but come with the cost of causing unacceptable damage to normal tissue.

During these early stages of tumour growth high doses of radiation therapy can with a high probability, eradicate a cancer but come with the cost of causing unacceptable damage to normal tissue. A specific goal of improving the technology of radiation therapy is to reduce the probability of damage to normal tissue. Achieving this goal may allow delivery of higher doses with an associated increase in the chance of controlling the tumour. One of the challenges in radiation therapy is that tumours do not come in shapes that are easy to treat. Tumours extend into cavities and push aside healthy organs growing into complex 3D shapes. The careful shaping of the radiation beams to deliver dose distributions that match the 3D shape of the target is known as 3D conformal radiotherapy (3DCRT). Intensity Modulated Radiotherapy (IMRT) is an advanced form of 3DCRT that allows the delivered dose to be closely tailored to the shape of complex tumour volumes while sparing neighbouring healthy tissues. One of the consequences of increasing the conformality of radiation therapy is an increased sensitivity to errors in the preparation and execution of the treatment. If the maximum gain in the treatment outcome using 3DCRT and IMRT techniques is to be achieved then it is crucial that the correct volume is treated to the correct dose on each day of the treatment. This requires new improved methods and techniques for verifying the daily delivery of the treatment. In this project we aim to develop the use of online digital imaging devices for measuring the delivered dose during treatment. This will increase the confidence with which these new conformal radiotherapy techniques can be delivered allowing their true potential for improving patient treatment outcomes to be realised.Read moreRead less
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.

We will create a new class of cancer radiotherapy system that solves the complex problem of how to target a tumour with precision and accuracy even as the patient’s anatomy changes during treatment. Our Nano-X system is built with real-time imaging guidance and treatment adaptation at the heart of the design process; and complex processing tasks have been moved from hardware to software, enabling radical changes to machine design. Together these innovations will ensure better treatment outcomes.
