Radiation treatment planning for volumetric modulated arc therapy (VMAT): Optimization and heuristics

Coauthor: Vicky Mak-Hau


Volumetric-modulated arc therapy (VMAT) is a recent technological development in the area of cancer radiation treatment, where the aim is the generation of a treatment plan involving decisions of appropriate radiation dosages, angles and collimator shapes. The problem is computationally very challenging, in particular considering additional problem features such as time limitations. In this talk, we will discuss an integer programming formulation for this problem, and improvements on this formulation using some linearization techniques and valid inequalities. We will present some polyhedral results, and also discuss a branching and column generation framework specifically designed for this problem. We will discuss some computational results, as well as possible future extensions.
