X-RAY INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/224558
Kind Code:
A1
Abstract:
[Problem] To provide an X-ray inspection device comprising a processing means for taking in and processing X-ray images acquired by a two-dimensional X-ray detector disposed such that the two-dimensional X-ray detector and an X-ray generator sandwich a body under inspection, the X-ray inspection device being capable of generating a CT image for the entirety of a relatively large body under inspection even if the storage capacity of the memory of the processing means is reduced. [Solution] By alternatingly carrying out an image acquisition operation and a movement operation, an X-ray inspection device 1 causes a two-dimensional X-ray detector 4 to acquire, over 360° and at prescribed angular intervals in a relative rotation direction, X-ray images of a body 2 under inspection that are divided in the left-right direction and are of a prescribed position in the vertical direction. After taking in a prescribed number of X-ray images, a processing means for taking in and processing the X-ray images acquires, from the acquired X-ray images, CT image creation data including the coordinates of prescribed positions in the acquired X-ray images and the brightnesses at the coordinates, and starts prescribed computation for generating a CT image of the body under inspection using the CT image creation data.
