The choice of a plan for radiotherapy treatment for an individual cancer patient requires the careful trade-off between the goals of delivering a sufficiently high radiation dose to the tumour and avoiding irradiation of critical organs and normal tissue. To support the treatment planner in this task it is necessary to visualize these trade-offs. The treatment planning problem can be formulated as a multi-objective optimization problem. We present a method to compute the optimal trade-offs for this problem and plot them in three dimensions. Furthermore, by computing a finite set of treatment plans that are well distributed across the entire trade-off surface, we support the treatment planner in identifying the best available plan for the patient under consideration.
