  • Patent number: 10141081
    Abstract: A phase grating for a phase contrast X-ray imaging device has a transverse surface which is to be aligned substantially transversely with respect to a radiation incidence direction and which is spanned by an x-axis and a y-axis perpendicular thereto. The phase grating is formed from a multiplicity of grating webs composed of a basic material, which are arranged alternately with optically denser interspaces. The grating webs subdivide the transverse surface into grating strips which are in each case elongated in the y-direction and which are lined up parallel alongside one another in the x-direction. The phase grating has in each grating strip along a z-axis, which is perpendicular to the transverse plane, a homogeneous total thickness of the basic material which always differs between adjacent grating strips. At least one grating web extends within the transverse surface over a plurality of grating strips.

  • Patent number: 9763634
    Abstract: A phase-contrast x-ray imaging device is particularly suited for the medical field. The device includes an x-ray source for generating an x-radiation field and an x-ray detector having a one-dimensional or two-dimensional arrangement of pixels. A phase-contrast differential amplifier is positioned between the x-ray source and the x-ray detector. The phase-contrast differential amplifier amplifies spatial phase differences in the x-radiation field during operation.

  • Patent number: 9532760
    Abstract: An embodiment of the invention relates to an X-ray device, more particularly for phase-contrast imaging in the medical sector. In at least one embodiment, the X-ray device includes an X-ray radiation source, a coherence grid, a phase grid and an X-ray detector from a number of pixels arranged in a matrix, the pixels including a lens grid.
