Radiation therapy is a mainstream treatment method that can significantly prolong life, but the damage it causes to healthy tissue is problematic. “Research into the area of radiotherapy dosimetry has, to date, focused on external beam radiotherapy, delivered by linear accelerator machines [LINACs],” says Dr Sinéad O’Keeffe of the University of Limerick (UL). “Here, the sensor is placed externally on the patient’s skin, in order to monitor the actual dose delivered, in comparison to that planned.
We are now looking to test a groundbreaking sensor [called a dosimeter] which allows for real-time checks on prescribed versus delivered radiation doses. We are hoping to significantly improve quality assurance standards in clinical applications without extending treatment delivery times. “Crucially, our device is smaller than current dosimeters, making it suitable for minimally invasive in…
