Image guidance technology has evolved and seen widespread application in the past several decades. Advancements in the diagnostic imaging field have found new applications in radiation oncology and promoted the development of therapeutic devices with advanced imaging capabilities. A recent example is the development of linear accelerators that offer magnetic resonance imaging for real-time imaging and online adaptive planning. Volumetric imaging, in particular, offers more precise localization of soft tissue targets and critical organs which reduces setup uncertainty and permit the use of smaller setup margins. We present a review of the status of current imaging modalities available for radiation oncology and its impact on target margins and use for adaptive therapy.
图像引导技术在过去几十年中不断发展并得到广泛应用。诊断成像领域的进步在放射肿瘤学中找到了新的应用，并推动了具有先进成像功能的治疗设备的发展。最近的一个例子是开发了能够提供实时成像和在线自适应计划的磁共振成像功能的线性加速器。特别是容积成像，可以更精确地定位软组织靶区和关键器官，减少设置不确定性，并允许使用更小的设置边界。我们回顾了放射肿瘤学中当前可用的成像方式及其对靶区边界的影响以及自适应治疗的应用。
