Professor Michael Lerch and Dr Enbang Li from the Centre of Medical Radiation Physics were recently featured on Vox FM and 2ser radio.

The devastating impact of cancer is only too well known and the incidence of cancer unfortunately continues to grow. External beam radiation therapy is one of the most important modalities for the treatment of cancers. Synchrotron microbeam radiation therapy (MRT) is a novel pre-clinical radiotherapy that uses very fine x-ray beams (thinner than the width of a human hair) to treat cancer, allowing treatment doses much higher than conventional radiotherapies to be delivered to the target. In this work we have developed and successfully tested a plastic scintillator fibre optic senor with a one-dimensional spatial resolution of 50 micrometres (0.05 mm). We have shown that this sensor is able to measure the radiation treatment dose in MRT which is essential for ensuring the quality assurance of this exciting new radiation oncology modality.
