Industrial digital radiography is a system in which a detector is used as a photosensitive material, and a signal reaching the detector is processed to present a digitized image.
Industrial digital ray systems typically include a source of rays, a detector, a mobile platform, an image processing and display system. The ray source and the detector are generally of a U-shaped integrated structure, the distance and the position are relatively fixed, the plane of the detector is vertically placed during detection, and the test piece is placed on the moving platform and is placed between the ray source and the detector. Scattered radiation, which may be generated when the radiation reaches the edge of the specimen, causes a "side-etching effect" that interferes with normal signals. Conventional film processing equipment typically employs the following methods to avoid or eliminate the "edge erosion effect": the test piece and the film are horizontally placed on the ground or a platform, and the high-density substance is placed at the edge of the detection area to shield the test piece and the film. However, in the industrial digital ray system, the detector plane is vertically arranged, so that the high-density substance is difficult to directly place for shielding and is not easy to adjust.
