  • Title: A Plastic Optical Fibre (POF) Based Real-Time Dosimiter for Clinical Radiotherapy
  • Abstract: A novel extrinsic optical fibre X-Ray dosimeter for biomedical applications is presented. The scintillation material in the sensor tip emits visible light upon exposure to x-ray energy and the resultant low intensity light is coupled to a PMMA (poly methyl methacrylate) plastic optical fibre, which guides it towards a distal fluorescent optical spectrometer at 30m distance. Initial has shown the scintillating optical fibre X-ray dosimeter exhibits excellent sensitivity and repeatability upon excitation from a calibrated Clinical Linear Accelerator (LinAC) source. Recent results from extensive on-site testing at radiotherapy clinics at UCLA (USA), Belfast City Hospital (UK) and 1st Hospital Harbin (China) are presented and the performance of the sensor assessed.
  • Biography: Elfed Lewis graduated with BEng (Hons) in Electrical and Electronic Engineering from Liverpool University in 1978 and was awarded his PhD from the same institution in 1987. In 1996 he joined University of Limerick at which time he formed the Optical Fibre Sensors Research Centre. He is Associate Professor and Director of the Optical Fibre Sensors Research Centre, which he founded in 1996. He is Fellow of Institute of Physics, IET, BCS and Senior member IEEE. He has authored and co authored more than 70 journal papers and made in excess of 200 contributions to international conferences. He currently holds 5 patents on Optical Fibre Sensor Devices. The Optical Fibre Sensors Research Centre under the leadership of Professor Lewis is engaged in investigating sensors for environmental monitoring (e.g. water quality, vehicle exhaust emissions,), food quality assessment and parameters of high power microwave sources (e.g. Electric Field, Electron Beam proximity) and medical devices. In 2005 he was recipient of the University of Limerick Special Achievement in Research Award and was a Fulbright Scholar with CREOL (University of Central Florida) in 2008. He is currently Distinguished Lecturer for IEEE Sensors Council for the period July 2013-June 2015.
