Abstract：
In recent years, proton therapy centres have begun to shift from conventional 2D-kV imaging to volumetric imaging systems for image guided proton therapy (IGPT). This is likely due to the increased commercial interest and availability of volumetric imaging systems, as well as the shift from passively scattered proton therapy to intensity modulated proton therapy. Currently, there is no standard modality for volumetric IGPT, leading to variation between different proton therapy centres. This article reviews the reported clinical use of volumetric IGPT, as available in published literature, and summarises their utilisation and workflow where possible. In addition, novel volumetric imaging systems are also briefly summarised highlighting their potential benefits for IGPT and the challenges that need to be overcome before they can be used clinically.
摘要：
近年来,质子治疗中心已经开始从传统的2D-kV成像转移到用于图像引导质子治疗（IGPT）的体积成像系统。这可能是由于增加的商业兴趣和体积成像系统的可用性，以及从被动散射质子疗法到强度调节质子疗法的转变。目前,没有容积式IGPT的标准模式，导致不同质子治疗中心之间的差异。本文回顾了已报道的容量IGPT的临床应用，如已出版文献中所述，并在可能的情况下总结其利用率和工作流程。此外,本文还简要总结了新型容积成像系统,强调了它们对IGPT的潜在益处以及在临床使用前需要克服的挑战.
