Device to Prevent Radiotherapy Errors

Scientists at the University of Bristol, Swansea University and the Bristol Haematology and Oncology Centre are developing a device to reduce the risk of radiotherapy mistreatment.   The device will detect changes to the radiation beam and immediately identify inaccurate treatments, allowing errors to be corrected before the patient suffers any adverse consequences. This device will be based on a thin silicon camera system that will not interfere with the radiation beam but will provide the radiographer with a real-time image of the beam as it is delivered. Radiation therapy uses various components to vary radiation intensity, so that the tumour is accurately targeted and damage to the surrounding tissue reduced. Changes to radiation beam, however, cannot be detected. If fault occurs, it may not be immediately spotted, which can result in mistreatment.
