Summary on inverse optimisation

• Inverse planning means DVH or biological optimisation according to clinically motivated constraints

• Constraints are expressed by the objective function

• Optimisation is achieved with fast gradient algorithms if beam directions are pre-selected

Knowledge based solutions

• Practical problem: Planning is time consuming • Knowledge based planning: Use your previous planning expereince and start with a very good initial plan • Based on achieved DVH from a library of plans (already done)
