  • Publication number: 20220005238
    Abstract: The present invention relates to an apparatus (10) for alveoli based visualization in dark-field or phase-contrast X-ray imaging. It is described to provide (210) a dark-field or phase-contrast X-ray image of a region of interest of an object, wherein image data are represented in units of a dark-field or a phase-contrast signal. A calibration is provided (220) relating dark-field or phase-contrast signal to an alveoli index in a lung. The calibration is utilized (230) to convert the dark-field or phase-contrast X-ray image of the region of interest of the object into an alveoli based image of the region of interest of the object, wherein the image data are represented in units of the alveoli index. The alveoli based image is outputted (240).

  • Patent number: 11189391
    Abstract: The invention relates to a method of manufacturing a structured grating, a corresponding structured grating component (1) and an imaging system. The method comprising the steps of: providing (110, 120, 130) a catalyst (30) on a substrate (20), the catalyst (20) having a grating pattern; growing (140) nanostructures (50) on the catalyst (30) so as to form walls (52) and trenches (54) based on the grating pattern; and filling (160) the trenches (54) between the walls (52) of nanostructures (50) using an X-ray absorbing material (70). The invention provides an improved method for manufacturing a structured grating and such structured grating component (1), which is particularly suitable for dark-field X-ray imaging or phase-contrast imaging.
