  • System and method for phase-contrast X-ray imaging using a multi-sector source grating
    Patent number: 9632040
    Abstract: A differential phase contrast X-ray imaging system includes an X-ray illumination system, a beam splitter arranged in a radiation path of the X-ray illumination system, and a detection system arranged in a radiation path to detect X-rays after passing through the beam splitter.
    Type: Grant

  • Large field of view grating interferometers for X-ray phase contrast imaging and CT at high energy
    Patent number: 9329141
    Abstract: A device and method of the present disclosure provides large field-of-view Talbot-Lau phase contrast CT systems up to very high X-ray energy. The device includes microperiodic gratings tilted at glancing incidence and tiled on a single substrate to provide the large field-of-view phase contrast CT system. The present disclosure is a simple, economical, and accurate method for combining multiple GAIs into a larger FOV system, capable of performing phase-contrast tomography (PC-CT) on large objects. The device and method can be applied to medical X-ray imaging, industrial non-destructive testing, and security screening.
