The use of imaging to maximize precision and accuracy throughout the entire process of radiation therapy (RT) delivery has been called "Image-guided RT" (IGRT). RT has long been image guided: in fact, historically, the portal films and later electronic megavoltage images represented an early form of IGRT. A broad range of IGRT modalities is now available and adopted. The target location may be defined for each treatment fraction by several methods by localizing surrogates, including implanted fiducial markers, external surface markers or anatomical features (through planar imaging, fluoroscopy, KV or MV computed tomography, magnetic resonance imaging, ultrasound and X-ray imaging, electromagnetic localization, optical surface imaging, etc.). The aim of the present review is to define practical recommendations for IGRT.
在放射治疗（RT）实施的整个过程中，利用成像技术以实现最高的精准度和准确性，这被称为“图像引导放射治疗”（IGRT）。放射治疗长期以来一直是图像引导的：事实上，从历史角度来看，射野片以及后来的电子兆伏级图像代表了IGRT的早期形式。现在有多种IGRT模式可供使用并已被采用。通过定位替代物（包括植入的基准标记、体表标记或解剖特征），可以通过几种方法为每个治疗分次定义靶区位置（通过平面成像、透视、千伏或兆伏计算机断层扫描、磁共振成像、超声和X射线成像、电磁定位、光学表面成像等）。本综述的目的是为IGRT确定实用的建议。
