Tungsten alloy anti-scatter grids are anti-scatter devices used in X-ray imaging systems, and their working principle mainly relies on the X-ray absorption properties of tungsten alloy materials. During the X-ray imaging process, X-rays generate both direct rays and scattered rays after passing through an object, with the latter potentially causing image blurring. Tungsten alloy anti-scatter grids are composed of a series of parallel tungsten alloy strips, which have a high density and are capable of effectively absorbing scattered X-rays, while allowing the direct X-rays to pass through the gaps of the grid and reach the detector. This selective absorption helps improve the contrast and clarity of the image.
