Radiographic imaging and tomography (RadIT) come in many types such as x-ray imaging and tomography (IT), proton IT, neutron IT, muon IT, and more. We identify five RadIT themes: physics, sources, detectors, methods, and data science, which are integral parts of image interpretation and 3D tomographic reconstruction. Traditionally, RadIT has been driven by medicine, non-destructive testing, material sciences, and security applications. The latest thrusts of growth come from automation, machine vision, additive manufacturing, and virtual reality (the "metaverse"). The five RadIT themes parallel their counterparts in optical IT. Synergies among different forms of RadIT and with optical IT motivate further advances towards multi-modal IT and quantum IT.
放射成像和层析成像（RadIT）有多种类型，例如 X 射线成像和层析成像（IT）、质子 IT、中子 IT、μ子 IT 等等。我们确定了 RadIT 的五个主题：物理、源、探测器、方法和数据科学，这些都是图像解释和 3D 层析重建的组成部分。传统上，RadIT 一直受到医学、无损检测、材料科学和安全应用的推动。最新的增长动力来自自动化、机器视觉、增材制造和虚拟现实（“元宇宙”）。RadIT 的这五个主题与光学 IT 的对应主题平行。不同形式的 RadIT 之间以及与光学 IT 的协同作用，推动了向多模态 IT 和量子 IT 的进一步发展。
