| Summary: | Specialised treatment modalities in radiation therapy demand for radiation sensors with high spatial resolution and fast response. More than 60% of cancer patients receive a form of radiation therapy for cure and control of tumours. Scintillation dosimetry utilising fibre optic coupling arrangement has emerged as one of the most promising candidates for small-field ionising radiation dose measurements. Recent advances have also explored the possibilities of in vivo dose measurements using similar apparatus. In this study, phosphorus-doped silica optical fibre scintillators, fabricated inhouse using Modified Chemical Vapour Deposition (MCVD) technique, have been developed in conjunction with a fibre optic coupled radioluminescence (RL) signal acquisition system. Together, they make a real-time, remote dosimetry system for use in megavoltage X-ray environment (radiotherapy range). |
