Technology measures radiation dose received during anticancer treatment

Device reduces excessive doses and has the potential to make radiotherapy safer and effective, particularly for children

With the latest figures from the World Health Organisation showing that Australia has the highest rate of cancer cases per capita in the world, ahead of New Zealand, North America and Western Europe, and nearly double the global average, researchers from the University of Wollongong (UOW) have invented a new technology that allows for a safer and more effective way of treating cancer, especially in children.

The novel device, known as 'MOSkin', detects how much radiation patients are exposed to during radiotherapy, in real time.

With nearly two-thirds of cancer patients receiving radiotherapy during their illness, inventor of the technology, Professor Anatoly Rozenfeld, said it is imperative to ensure its safety and success.

"While contemporary radiation therapy is very accurate, quality assurance during the treatment delivery is paramount because overdoses of radiation can induce chronic or acute side effects, such as skin erythema," Professor Rozenfeld said.

"MOSkin monitors the amount of radiation the skin receives and hence this side effects can be more closely controlled."

Professor Rozenfeld, who is the Director of the Centre for Medical Radiation Physics at UOW, said radiation overdoses could also increase the probability of secondary cancer.

By monitoring skin dose measurements in real time, Professor Rozenfeld said it would help improve techniques to minimise out-of-field doses, which are of particular concern in children.

Due to the novel design allowing non invasive skin dose measurements, 'MOSkin' recently won a highly competitive Commercialisation Australia Skills and Knowledge Grant to help commercialise the technology, which has already been developed into prototypes for a range of radiotherapy treatments, and has been trialled by over 20 international cancer centres, hospitals and research institutions around Australia and internationally.

"This technology has been developed over 10 years of research, and we have received very positive scientific and clinical testing results," Professor Rozenfeld said.

"We are pleased that both its technological value and commercial value have been acknowledged by a Chinese patent and the commercialisation grant."
