System for optimizing conformity of dose line

The invention provides a dose line conformity optimization system, which comprises a processor, and is characterized in that the processor is configured to execute the following steps: obtaining an index function used for representing the conformity of a target area and a specified dose line; and establishing a loss function according to the index function and performing optimization to obtain an optimal specified dose line corresponding to the target area. According to the invention, the conformity of the target area and the specified dose line can be directly and conveniently controlled, and the problems of trouble of manual ring drawing and unobvious conformity control effect by setting a drop function are avoided. 本发明提供了一种剂量线的适形度的优化系统，包括处理器，所述处理器被配置为执行如下步骤：获取用于表征目标区域与其指定剂量线的适形度的指标函数；根据所述指标函数建立损失函数并进行优化，以得到对应于所述目标区域的最优指定剂量线。本发明可以直接、便捷地控制目标区域与其指定剂量线的适形度，避免了手工画环的麻烦和设置跌落函数控制适形度效果不明显的问题。
