Does dr need a filter?

After the X-ray passes through the human body, a continuous emission line with a longer wavelength and an indeterminate direction is generated, that is, the scattered line. The greater the energy of the original emission line, the thicker the penetrating limb and the higher the projection conditions, the more scattered lines will be generated. Scattered rays also have fluorescent and photographic effects, which can lighten the film and reduce the contrast and sharpness of the image. In order to reduce and eliminate the adverse effects of scattered rays in the projection, the most effective way is to use a filter. DR equipment is best to use a filter.
