Abstract

Scintillation-based fiber dosimeters are a powerful tool for minimally invasive localized real-time monitoring of the dose rate during brachytherapy (BT). We present a fabrication method for mass manufacturing of scintillating sensor tips which are to be attached to polymer optical fiber (POF) to enable fiber-optic dosimetry. The scintillating sensor tips consist of inorganic scintillators, dispersed in a polymer host. The manufacturing is done by means of a custom compression and transfer moulding process implemented on a commercially available hot embossing machine. We show the manufacturing of 237 sensor tips, which are subsequently attached to the end of the POF using UV-curable adhesive. Finally, we perform dosimetry experiments in water phantoms which show a great potential for in-vivo dosimetry for brachytherapy, both for Low Dose Rate (LDR) and High Dose Rate (HDR) BT.
