    摘要: A radiation planning system includes a predictor-corrector optimizer unit which computes a predicted dose based on a collection of control points with a current approximate dose, each control point with a corresponding set of leaf positions, and determines an additional control point with a corresponding set of leaf positions based on a difference of the predicted fluence and the current approximate fluence through a least cost or shortest path in a layered graph structure of realizable leaf positions. Tools are described to help a planner to evaluate the effect of parameter changes to the current plan based on an identified zone of influence. The planner interactively views the current plan based on a visualization of the plan objectives and correlations between the objectives.

    摘要: The present invention relates to a radiotherapy planning system (100) for determining a solution (101) corresponding to a fluence profile. The invention proposes to use a Pareto frontier navigator (140) to select the best plan from a set of various auto-planned solutions. An interactive graphical user interface (400) is provided to the planner to navigate among convex combinations of auto-planned solutions. This proposed Pareto plan navigation can be considered as a further optional refinement process, which can be applied to find the best plan in those cases where auto-generated solutions are not fully satisfying the planner's requirements. The navigation tool (400) moves locally through a set of auto-generated plans and can potentially simplify the planner's decision making process and reduce the whole planning time on complex clinical cases from several hours to minutes.

    摘要: The invention relates to a planning device 2 for positioning treatment applicators 8. The device 2 comprises a providing unit 4 configured for providing a distance r to be considered between applicator entry points 10 and a processor 6. It has been found that when utilizing treatment applicators, in particular ablation treatment applicators, placing two or more applicators closely together increases the risk of ablating and damaging more tissue than required for the therapy success. By configuring the processor 6 to inactivating all entry points within a distance r from a currently selected entry point such that these entry points are unavailable to further optimization iterations, and then conducting a further optimization iteration, an optimal applicator configuration can be provided that is effective with regard to the therapy success while the risk of ablating more tissue than required is reduced.
