DETECTOR AND VISUALIZATION SYSTEM FOR X-RAY PHASE-CONTRAST IMAGING OF TOMOSYNTHESIS Russian patent published in 2019 - IPC A61B6/02 A61B6/04 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to X-ray phase contrast imaging tomosynthesis. X-ray detector device comprises linear detectors, wherein each linear detector is configured to detect a moire pattern in at least part of the X-ray beam incident on such a linear detector, wherein each linear detector has independent detector lines, and width W of each linear detector is equal to one period or multiple integer number of periods of moire pattern. Imaging system comprises an X-ray detector device, an X-ray source device, a grating device configured to generate a moire pattern in the X-ray beam, and a portal, wherein the X-ray source device, the grating device and the X-ray detector device are installed on the portal. X-ray phase contrast imaging tomosynthesis involves the following steps: a) providing an X-ray beam passing through the X-ray detector device, and b) detecting a moire pattern in at least a portion of the X-ray beam. Machine readable medium comprises a computer program for controlling a device or system.

EFFECT: use of inventions enables combining registration of tomosynthesis data with registration of phase contrast data, which reduces the dose of X-ray radiation.
