Multi-criteria optimization in RayStation

Multi-criteria optimization/ rayNavigator

rayNavigator introduces the concept of multi-criteria optimization (MCO), which provides an alternative optimization workflow. Instead of the planner performing iterative optimization with adjustments to optimization functions and weights RayStation generates a set of Pareto plans.

These plans respect all constraints and no objectives can be improved without impairing another one. Based on these plans, the planner or physician can manipulate sliders in real time to balance between clinical trade-offs.

An interactive navigation tool for selecting the best clinical trade-off based on fluence-based anchor plans.

  • Automatic tool for generating a deliverable treatment plan from this selection.
  • rayNavigator is available for IMRT, VMAT and Proton PBS planning.
