X-ray dark-field imaging (XDFI), which we have developed using synchrotron radiation light sources, can image soft tissues in three dimensions with high contrast comparable to that of stained pathological images. In this lecture, we introduce the imaging principle of XDFI (Part 1), the CT reconstruction method based on XDFI (Part 2), and the application of XDFI to medical research (Part 3), with the aim of familiarizing many readers with XDFI in an easy-to- understand manner. In this first article, an overview of XDFI and the imaging principle of XDFI are introduced, and then the mechanism of obtaining projection and tomographic images is described.
