Optical Fibre Dose Imaging for Adaptive Brachytherapy

ORIGIN aims to deliver more effective, photonics-enabled, brachytherapy for cancer treatment through advanced real-time radiation dose imaging and source localisation. This will be achieved by the development of a new optical fibre based sensor system to support diagnostics-driven therapy through enhanced adaptive brachytherapy. A 16-point optical fibre sensors system will be developed, alongside a dedicated data acquisition system, providing a dose mapping system with a spatial resolution of 0.5mm for high dose-rate and 3mm for low dose-rate therapy and time resolutions of 0.1s and 0.5s, respectively, with 5% uncertainty. This is a 50% improvement in uncertainty over existing systems. Further interrogation of the optical signal will provide real-time monitoring of the radiation source location during treatment. The ORIGIN system will be integrated into existing clinical brachytherapy treatment planning and delivery systems to confirm that the dose prescribed to the tumour is achieved, whilst ensuring the dose to organs at risk (OARs) is within acceptable limits. This will provide for optimised dose-led, patient-oriented, personalised treatment plans leading to improved patient outcomes and prevention of treatment errors, with the potential to reduce the overall risk of treatment error by 55%.
