摘　　要：自适应放疗(ART)技术可以在放疗过程中的某个或某些时间点调整治疗计划,以应对患者在治疗分次间和/或分次中的器官变化。ART策略是在ART实施过程中具体采用的计划调整方式、方法,合理选择ART策略对于平衡治疗时间与剂量获益至关重要。目前的策略选择主要依赖于医务人员的主观判断。近年来,国内外医疗机构利用人工智能方法建立预测模型,以期实现ART策略的自动、快速和准确选择。本文对在线ART的策略选择进行综述,先后介绍了ART商业系统当前提供的策略类型、医疗机构选择ART策略的现状及存在的问题,以及ART策略的自动选择研究现状及应用前景。Adaptive radiotherapy(ART)can adjust the treatment plan at one or certain time points during the process,thereby responding to inter-fractional and/or intra-fractional changes in the patient's organs.The ART strategy refers to the specific methods used to adjust the treatment plan in the ART process,proper selection of an ART strategy is crucial to balancing treatment time and dose benefits.Currently,the strategy selection relies mainly on the subjective judgment of medical professionals.In recent years,both domestic and international medical institutions have employed artificial intelligence methods to build prediction models for automatic,fast and accurate selection of ART strategies.This article reviews the strategy selection of online ART,and sequentially introduces the types of strategies currently provided by the ART commercial systems,the current status and existing problems of ART strategy selection by medical institutions,and the present research status and application prospects of automatic ART strategy selection.
