The invention relates to
optical imaging equipment, and particularly relates to an X-
ray anti-scattering
grating based on an orthogonal structure. The X-
ray anti-scattering
grating is used for improving the quality of an X-
ray image and is applied to X-ray machines and CT detection equipment in the fields of
medical image diagnosis and treatment, industrial
nondestructive testing, security detection and the like. The X-ray anti-scattering
grating is used for filtering photons scattered by a researched detected
human body, organs and articles and only retaining photons emitted by a source to improve an X-ray photographic image. The X-ray anti-scattering grating based on the orthogonal structure not only reduces the influence of X-ray
scattering radiation on the resolution ratio of the quality of the detected image, but also can reduce the influence of X-ray
direct radiation on the quality degradation of the detected image, effectively solves the problems of
low resolution ratio, large error and the like of the X-ray detected image in the prior art, obviously improves the quality of the X-ray image detected image, or can reduce the
radiation damage to a detected patient or object exposed to a high
dose under the condition of obtaining the same quality of the detected image.
