摘要多叶准直器是医用直线加速器中遮挡射线的装置，在放射治疗中调节射野形状和剂量分布，直接影响靶区与危及器官受量。目前，多叶准直器在结构上呈现出多样化，各类多叶准直器的剂量学对比也同步推进。本文按多叶准直器的基本构成将其分类，分别介绍各主流加速器厂商产品的硬件结构与设计特点（包括瓦里安Millennium MLC、HD120MLC、Halcyon；医科达MLCi/i2、Agility；安科瑞 InCise 2 MLC、TomoTherapy二元气动光栅）；在临床应用评价方面，以鼻咽癌放疗计划为主，综述多叶准直器剂量学表现的对比研究，以及相关条件设置对剂量分布的影响。本文综述的多叶准直器的设计与临床应用评价，为更具创新性设计方案的提出、临床个体化治疗中加速器的选择与参数设定提供参考。
