Adaptive planning strategies for MR-guided HDR prostate brachytherapy using a single needle MR-compatible robotic system

Abstract

In this thesis, we developed new methodologies which aim to tackle two issues that are likely to occur during MR-guided HDR prostate brachytherapy: needle positioning errors and changes of anatomy. We also developed a MR compatible needle tracking system based on FBG sensors which can measure the position of a needle with performance comparable or superior to current MR-based methods.
