Medical physicists on the Australian Radiation Safety and Nuclear Security Company (ARPANSA) have labored with the Worldwide Atomic Vitality Company (IAEA) to develop a world radiotherapy audit methodology.
The undertaking was led by consultants at ARPANSA’s Australian Scientific Dosimetry Service—Dr. Sabeena Beveridge and Dr. Andrew Alves. The findings have been printed within the journal Medical Physics.
Dr. Alves says ARPANSA developed a high quality assurance methodology to precisely calculate the radiotherapy dose and therapy placement. He says this can make high quality radiation therapy accessible to all sufferers regardless of the place they dwell.
“The IAEA called upon ARPANSA’s expertise in radiotherapy dose auditing to publish a verification method that can be used around the world to test the accuracy of film dosimetry,” Dr. Alves mentioned.
“We recommended film dosimetry because when employed accurately it is inexpensive, easy to use, widely available and, crucially, can test that the radiation dose will be directed at the cancerous tumor and not at healthy organs in the body.”
Movie dosimetry works as a result of when uncovered to radiation doses, the specialised movie modifications coloration.
These movies are positioned inside fashions of the human physique, known as phantoms, that are uncovered to radiation. The movies are then taken out of the fashions and analyzed by scientists.
Roughly 80,000 Australians acquired radiotherapy therapy within the final yr, with numbers persevering with to extend over time.
Because the Australian Authorities’s main radiation safety authority, ARPANSA helps accuracy in most cancers care, making certain that radiotherapy is correct by our audit program.
