MULTIDIRECTIONAL PHASE-CONTRAST X-RAY VISUALIZATION Russian patent published in 2017 - IPC A61B6/00 G21K1/00 

FIELD: physics.

SUBSTANCE: system includes an X-ray source, a detection circuit and a grating circuit. The detection circuit comprises, at least, eight linearly parallel units located in the first direction extending linearly in the perpendicular direction. The X-ray source, the detection circuit and the grating circuit are adapted to effect the object movement to the scanning direction, wherein the scanning direction is parallel to the first direction. The grating circuit comprises a phase grating structure mounted between the source and the detector, and an analyzer grating structure mounted between the phase grating structure and the detection circuit. The phase grating structure and the analyzer grating structure have a set of the corresponding linear gratings. The first parts of the phase gratings and the analyzer gratings have slits in the first direction, the second parts of the phase gratings and the analyzer gratings have slits in the second direction, different from the first one. At least, four adjacent lines of the linear detector units are connected to the first phase gratings and the analyzer gratings, and, at least, four adjacent lines of the linear detector blocks are connected to the second phase gratings and the analyzer gratings, and remain fixed relative to each other and to the detection circuit for moving the gratings. The method is carried out through the system. The computer-readable medium stores instructions for controlling the system by the method.

EFFECT: using the invention allows to expand the technical means range for X-ray phase-contrast object visualization.
