In this review article we describe the development of grating-based X-ray phase-contrast imaging, with particular emphasis on potential biomedical applications of the technology. We review the basics of image formation in grating-based phase-contrast and dark-field radiography and present some exemplary multimodal radiography results obtained with laboratory X-ray sources. Furthermore, we discuss the theoretical concepts to extend grating-based multimodal radiography to quantitative transmission, phase-contrast, and dark-field scattering computed tomography.
在这篇综述文章中，我们描述了基于光栅的 X 射线相衬成像的发展，特别强调了该技术在潜在的生物医学应用方面的潜力。我们回顾了基于光栅的相衬和暗场射线照相术的成象基本原理，并给出了一些用实验室 X 射线源获得的示例多模态射线照相术结果。此外，我们还讨论了将基于光栅的多模态射线照相术扩展到定量透射、相衬和暗场散射计算机断层成像的理论概念。
