Summary
Prostate cancer is one of the most commonly diagnosed cancers in men over 55 years of age. Approximately 30% of all diagnosed cancers in this age group are prostate carcinomas. Low and high dose rate brachytherapy are newly established treatment options for early-stage, low-risk, prostate cancer and are an alternative to curative prostatectomy in most patients. Local control and cure of prostate cancer is greatly influenced by the dose distribution generated by both the treatment techniques.

Low and high dose rate brachytherapy are newly established treatment options for early-stage, low-risk, prostate cancer and are an alternative to curative prostatectomy in most patients. Local control and cure of prostate cancer is greatly influenced by the dose distribution generated by both the treatment techniques. Treatment plans must be able to deliver a prescribed dose in the tumour, with adequate margins, while minimising the dose delivered to the surrounding normal tissue and critical organs. It is well recognised that, however skilful the radiation oncologist, an ideal dose distribution according to a treatment plan plan does not guarantee a well delivered dose. Complications such as impotence, severe radiation urethritis and severe rectal bleeding will arise if overdosing of the neuro-vascular bundle, urethra and rectum occurs respectively. This project is based on newly developed instrumentation that will allow continuous, realtime, in vivo, monitoring of the radiation dose levels in the urethra and rectum during brachytherapy treatment of prostate cancer. Such monitoring of the treatment procedure, has been identified as a high priority by the American Brachytherapy Society. The technique will allow extensive in vivo and post treatment studies to be performed by clinicians so as to measure the dose levels currently received and identify the optimum acceptable dose levels for future procedures. The outcomes of this project may well be able to be utilised in other forms of brachytherapy treament (e.g. breast, cervical cancer) and other radiation treatment modailities (e.g. conventional radiotherapy and intensity modulated radiotherapy) to also reduce complications associated with these treatment modalities.Read moreRead less
X-RATE: A Novel Radiation Detector Platform To Realize New Opportunities In Radiotherapy At The Australian Synchrotron

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.
3D-BrachyView: A 3D Real-time Virtual Reality Intra-operative Quality Assurance System For Brachytherapy

Summary
Radiation therapy is a major oncology modality for cancer treatment and more than 50% of cancer patients can benefit from radiotherapy at some stage of management. This project will develop two real-time, high spatial resolution dosimetry systems for quality assurance of contemporary radiation treatments of static and movable targets. It will be possible to minimize human and robotic system error so as to guarantee accurate cancer treatment delivery and improve the clinical outcomes of radiother ....Radiation therapy is a major oncology modality for cancer treatment and more than 50% of cancer patients can benefit from radiotherapy at some stage of management.
