Automatic Selection / Adjustment of Dwell Times T

It requires that user somehow defines “wishes”
-
User defines/selects rules for the dwell times T

(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.
