Summary

This chapter describes treatment planning optimization in brachytherapy and the design of a clinical decision support system. Brachytherapy refers to the placement of radioactive sources (seeds) inside a tumor site. The fundamental problem in treatment planning for brachytherapy is to determine where to place sources so as to deliver a sufficient radiation dose to kill the cancer, while limiting exposure of healthy tissue. We first present the sequence of steps that are involved in brachytherapy treatment planning. State-of-the-art mixed integer programming models are then described and some algorithmic approaches are outlined. The automated clinical decision support system allows for real-time generation of optimal seed configurations using ultrasound images acquired prior to seed implantation, and dynamic dose correction during the implantation process.
