Summary:The embodiment of the invention provides a method for optimizing a radiotherapy plan. The method comprises the following steps: acquiring a medical image, wherein the medical image comprises a region of interest of an object; inputting the medical image into a prediction model to determine dose distribution corresponding to the region of interest and uncertainty corresponding to the dose distribution; obtaining a plurality of optimization targets related to the region of interest; based on the dose distribution and the uncertainty, determining a probability result related to a probability that each optimization objective in the plurality of optimization objectives can reach; and based on the probability result and the plurality of optimization targets, optimizing the radiotherapy plan to obtain a target radiotherapy plan. 本申请实施例提供了一种用于优化放疗计划的方法。所述方法包括：获取医学影像，所述医学影像包括对象的感兴趣区域；将所述医学影像输入预测模型以确定与所述感兴趣区域对应的剂量分布以及所述剂量分布所对应的不确定度；获取与所述感兴趣区域相关的多个优化目标；基于所述剂量分布以及所述不确定度，确定与所述多个优化目标中每个优化目标能够达成的概率相关的概率结果；基于所述概率结果和所述多个优化目标，
