GRATING DEVICE FOR X-RAY VISUALIZATION DEVICE Russian patent published in 2018 - IPC G21K1/10 

FIELD: medicine.

SUBSTANCE: invention relates to grating device (1) for an X-ray imaging device, interferometric unit (2), X-ray imaging system (3), X-ray imaging method, and an element of a computer program for controlling such a device, and a computer-readable medium storing such an element of the computer program. Grating device (1) for the X-ray imaging device contains grating structure (10) and drive structure (20). Grating structure (10) contains a plurality of grating segments (11). Drive structure (20) is configured to move said plurality of grating segments (11) with at least the rotational component between the first position and the second position. In the first position, grating segments (11) are placed in the path of x-ray beam (30) so that grating segments (11) act on the parts of x-ray beam (30). In the second position, grating segments (11) are placed outside the paths of x-ray beam (30) so that the segments of grating (11) do not affect the parts of x-ray beam (30).

EFFECT: technical result is the choice to use differential phase-contrast imaging and/or dark field imaging in addition to or not in addition to the usual attenuation visualization, providing the flexibility for the clinician between phase-contrast and/or dark field examination and normal examination.
