Latest Advancements in Bi-Objective Treatment Planning for HDR Brachytherapy

In our bi-objective treatment planning method for HDR brachytherapy, we use a model-based multi-objective evolutionary algorithm to find a large set of treatment plans with different trade-offs between the two optimization objectives: coverage of the tumor and sparing of the organs at risk. I will present some of the latest advancements and some work in progress for this treatment planning method. This includes adaptations to the optimization model to be robust against varying clinical protocols, the application of a Graphics Processing Unit (GPU) to substantially reduce optimization time through large-scale parallelization, and some of the steps required to introduce bi-objective treatment planning in clinical practice.
