X-ray photograph system for phase contrast imaging of inspection object, has X-ray radiator with multitude field emission X-ray sources for transmitting quasi-coherent X-ray radiation

摘要

The X-ray photograph system has an X-ray detector (12) and an X-ray radiator (11) with multitude field emission X-ray sources (10) for transmitting of quasi-coherent X-ray radiation. A diffraction grating or phase grating (14) is arranged between an investigation object and the X-ray detector. An absorption grating or an amplitude grating (15) is arranged between the diffraction grating or phase grating and the X-ray detector.
