Document Type and Number:
Japanese Patent JP6947473
Kind Code:
B2
Abstract:
To enable an X-ray beam to be scanned even by a relatively small-scale configuration and yet make X-ray imaging possible in which an effect of scattered rays is suppressed.SOLUTION: An X-ray imaging device pertaining to one embodiment of the present invention has a rotating collimator 20 arranged in front of a radiation opening of an X-ray source 10 and moves it narrowing down X-ray beams 501-503 so that a subject 30 is scanned by a fan-shaped X-ray beam (X-ray fan beam). At this time, a line of a detector 40 reached by the X-ray having passed through the subject 30 is identified by detecting a rotation phase angle of the collimator 20. Meanwhile, integration image processing is performed using only a line signal of the detector 40 that may have been reached by the penetrated X-ray (discarding all other than the identified line signal).SELECTED DRAWING: Figure 1
