Improving the homogeneity of brachytherapy treatment plans generated by BRIGHT using a hotspot registration method based on connected component analysis

Abstract

In this thesis BRIGHT, a multi-objective evolutionary algorithm for the creation of treatment plans for high-dose rate brachytherapy for prostate cancer, is extended with a new objective to mitigate the formation of high dose contiguous volumes, i.e. hotspots. Multiple new objectives are tested on their performance to reduce hotspots, while minimally impacting existing objectives
