Forward Planning / Optimization

Automatic Selection / Adjustment of Dwell Times T i ▪ It requires that user somehow defines “wishes” - User defines/selects rules for the dwell times T i (e.g. Geometrical Optimization) - User defines the dose level at some “representative” points (Dose Point Optimization, Graphical Optimization) ▪ Since both “rules” and “representative” points can not describe fully a 3D dose distribution, planner goes over several loops (changing rules, combining with dose points) as in the case of manual adjustment, until a clinical acceptable plan is created.
