- X-ray_filter abstract "An X-ray filter is a device to block or filter out some or all wavelengths in the X-ray spectrum.X-ray filters are used to selectively attenuate (block) low-energy X-rays during medical x-ray imaging (radiography). Low energy x-rays (less than 30 keV) contribute little to the image as they are so heavily absorbed by the patient's soft tissues, particularly the skin. This absorption add to the risk of stochastic (e.g. cancer) or non stochastic radiation effects (e.g. tissue reactions). X-ray filtration may be inherent (due to the x-ray tube and housing material itself) or added (additional sheets of filter material). The total filtration must be at least 2.5 mm Aluminium (Al) equivalent, although there is an increasing trend to use greater filtration. Manufacturers of modern fluoroscopy equipment utilise a system of adding a variable thickness of copper (Cu) filtration according to patient thickness. This typically ranges from 0.1 to 0.9 mm Cu.X-ray filters are also used in X-ray crystallography, where crystalline lattice spacings can be determined using Bragg diffraction. The filters allow only a single X-ray wavelength to penetrate through to a target crystal, allowing the resulting scattering to determine the diffraction distance.".
