FIELD: medicine.
SUBSTANCE: mounting structure for a device of interferometric image formation contains a curved surface for placing an interferometric grid on it, wherein the curved surface is characterized by the presence of holes forming the grid, while the grid after its placement closes the specified holes. An assembly for the device of interferometric image formation contains a mounting structure and an interferometric grid. The assembly also contains a detector for interferometric image formation, containing radiation-sensitive detector pixels. The specified radiation-sensitive detector pixels are arranged in a pattern. The specified pattern can be aligned with holes located in the mounting structure after installation in the device of image formation. The device of interferometric image formation contains: an X-ray detector; an X-ray source characterized by the presence of a focal spot; and an interferometric node. The curved grid is focused on the focal spot. The interferometric node is located on or opposite the detector.
EFFECT: use of this group of inventions will improve the quality of obtained images.
