Image-guided radiotherapy (IGRT) aims to take into account the anatomical variations occurring during the course of radiotherapy, by direct or indirect visualization of the target volume followed by a corrective action. The movements of the target, or at least the set-up errors are corrected by moving the treatment table, corresponding to the simplest and most validated IGRT modality in a standard practice. The deformations of the target volume and organs at risk are however much more common, and unfortunately much more complicated to consider, requiring multiple planning before or during the treatment, corresponding to the adaptive radiotherapy strategies. The planning target volume must be carefully chosen according to these anatomic variations. This article reviews the modalities of IGRT, standard or under evaluation, according to the different tumour sites.
图像引导放射治疗（IGRT）旨在通过对靶区的直接或间接可视化，然后采取纠正措施，来考虑放射治疗过程中出现的解剖学变异。通过移动治疗床来校正靶区的移动，或者至少校正摆位误差，这在标准实践中对应于最简单且最有效的IGRT模式。然而，靶区体积和危及器官的变形更为常见，不幸的是，考虑起来要复杂得多，需要在治疗前或治疗期间进行多次规划，这对应于自适应放射治疗策略。必须根据这些解剖学变异仔细选择计划靶区体积。本文根据不同的肿瘤部位，综述了标准的或正在评估的IGRT模式。
