Fast And Efficient Assessment Of Dose In Small Targets In Radiotherapy: Effect Of Motion In Clinical Research And Implementation Of Dynamic Therapy
Funder

Funding Amount
$501,265.00
Summary
The continued progress of radiation therapy for cancer patients has been driven by technology developments that have increased the complexity of radiation delivery, but has come at the cost of increased potential for errors in radiation planning and delivery. The aim of this project is to implement an instrument for verification of treatment delivered to organs with large variation of shape and position due to respiration. This will enhance treatment outcome and patient quality of life.
Cancer Radiotherapy 2020: Accounting For Tumour Deformation In Real Time To Improve Treatment Outcome

Funding Amount
$371,616.00
Summary
Tumours in lung and prostate cancer change shape during radiotherapy treatment. This is not accounted for in current care, compromising the therapeutic efficacy. We will develop the first radiotherapy system that can adjust the radiation beam in real time to follow the changing tumour shape. We will assess the performance of the system and quantify the clinical benefit. It is expected that clinical implementation of this technique will improve the cure rates and decrease the treatment toxicity.
A Computerised Treatment Planning System For Synchrotron Radiotherapy Trials At The Australian Synchrotron’s Imaging & Medical Beamline.

Summary
Microbeam Radiotherapy (MRT) using synchrotron-generated X-rays has shown tremendous promise in pre-clinical trials in tumour-bearing rodents, with remarkable sparing of normal tissue. Synchrotron MRT has the potential to radically alter the way radiotherapy is performed for human cancers. Every radiotherapy patient undergoes some form of computerised treatment planning before their treatment starts.

Design And Application Of New Nanomaterials Theranostic Platforms For Targeted Treatment Of Cancer

Funding Amount
$530,626.00
Summary
The project aims to develop intelligent drugs that attract to malignant tumors like magnets. These powerful, next-generation chemotherapy drugs seek out cancerous cells, allowing physicians to see exactly where tumours lie. Nanoparticles inside the drugs then switch on upon contact with X-ray radiation beams. This new method, which can diagnose, deliver targeted therapy and monitor the response to therapy all at the same time, would reduce the amount of radiation needed to kill cancer cells.
Optimising Radiation Therapy Delivery For Cancer Patients Using Daily Image Guidance To Maximize Cure And Reduce Normal Tissue Side Effects
Funder
National Health and Medical Research Council
Funding Amount
$510,968.00
Summary
When using radiotherapy to kill tumours, the radiation beams need to be targeted at the tumour, plus a margin of error around it to ensure that it receives sufficient dose despite uncertainties in its exact location relative to reference points used for beam alignment. Advanced statistical modelling techniques applied to data collected from patients will be used to determine the optimal margin width for individual patients to maximise cancer cure while minimising normal tissue side effects.
First Ever System To Continuously And Directly Measure The Internal Anatomy To Guide Breast Cancer Radiation Treatment Under Deep Inspiration Breath Hold

Funding Amount
$409,766.00
Summary
We propose a first ever system to continuously and directly measure the internal anatomy of the patient during radiotherapy of left sided breast cancer to ensure correct position of patient and radiation beam. The proposed method involves no additional radiation dose to the patient. It relies on existing components of modern radiation treatment machines, requiring no additional equipment, which will make it easy to implement widely.

REVEALING MOLECULAR MECHANISMS OF THE SYNCHROTRON RADIATION-INDUCED BYSTANDER EFFECT
Funder

Funding Amount
$429,294.00
Summary
Radiotherapy, a major treatment for more than half of cancer patients, is based on the dogma that radiation kills targeted cells. The radiation-induced bystander effect, by which the neighbours of irradiated cells can also damaged, is a new paradigm. What is the "danger signal" which induces DNA damage in un-irradiated normal tissues, and what minimal volume of tissue needs to be irradiated to induce bystander damage? The answers could have a major impact on optimising radiotherapy treatment.
Very Fast, Accurate And Low Dose Imaging For Radiotherapy Treatments

Funding Amount
$650,651.00
Summary
This project will reduce scan times and imaging dose by an order of magnitude for an imaging modality that is the standard of care for lung cancer patients receiving radiotherapy. Specifically, scan times reduce from 4min to below 60sec, image quality will be improved and imaging dose will be reduced by 85%. These improvements not only improve treatment efficacy by improving the accuracy of radiotherapy delivery, they reduce treatment times and reduce discomfort to the patient.
