FIELD: physics.
SUBSTANCE: diffraction grating for shaping the X-ray differential phase-contrast images is provided with the first subarea including, at least, one section of the first grating structure and at least one section of the second grating structure. The first grating structure comprises intermitting multiple bands and intervals with the first grating orientation GO1. Note here that said bands are located to change the X-ray radiation phase and/or amplitude. Note here that intervals can transmit the X-ray beams. The second grating structure comprises intermitting multiple bands and intervals with the second grating orientation GO2. Note here that said bands are located to change the X-ray radiation phase and/or amplitude. Note here that intervals can transmit the X-ray beams. The first grating orientation differs from the second one.
EFFECT: higher image quality.
