图像制导技术在过去的几十年里得到了发展和广泛的应用。诊断成像领域的进步已经在放射肿瘤学中找到了新的应用，并促进了具有先进成像能力的治疗设备的发展。最近的一个例子是线性加速器的发展，它提供了磁共振成像的实时成像和在线自适应规划。特别是体积成像，可以更精确地定位软组织目标和关键器官，从而降低设置不确定性并允许使用更小的设置边缘。我们提出了一个审查的现状，目前的成像模式可用于放射肿瘤学和它的影响，对目标的利润和使用的适应性治疗。(C)2018爱思唯尔公司All rights reserved.
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. (C) 2018 Elsevier Inc.
