Subnanoradian X-ray phase-contrast imaging using a far-field interferometer of nanometric phase gratings
Hard X-ray phase-contrast imaging characterizes the electron density distribution in an object without the need for radiation absorption. The power of phase contrast to resolve subtle changes, such as those in soft tissue structures, lies in its ability to detect minute refractive bending of X-rays....
