Problems solved by technology

The disadvantage of this approach to reducing the scattered radiation is that not only the scattered radiation is absorbed into the anti-scatter grid, but also a part of the direct radiation will be absorbed, which will degrade the quality of the X-ray inspection image or necessitate the removal of the patient or object under examination. Exposure to a higher dose for the same image quality

Abstract

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.
