【 摘 要 】

The complexity of dose distributions has increased with the advent of intensity modulated radiation therapy (IMRT). For that reason, experimental measurements using 3D dosimeters with high spatial resolution are required to check the delivered dose. In this study a new 3D solid polymer dosimeter with absorbance and fluorescence responses to radiation is presented. Measuring fluorescence instead of absorbance improves the spatial resolution and eases the read out of the dosimeter. The proposed dosimeter is tissue-equivalent and can be moulded in any shape by a controllable and fast photopolymerization process.
