Qality Inspection Method And Equipment Of Antiscatter Grid For Digital Radiography System Use X-ray Film And Film Digitizer

摘要

The subject innovation is got as relates to the quality inspection, the correction method and apparatus of the non-scatter grid for a digital radiographic system using a X-ray film and the film digitizer, and more specifically to checking, correcting the quality of the digital radiographic system only the non-scatter grid, digital a radiation system quality check method, using a conventional X-ray film and the film digitizer grid line frequency than the (grid line frequency), showing the degree (grid Visibility) of the grid and FIG grid inhomogeneous test the (grid non-uniformity), and the correction as one to be developed to obtain a saving significant cost effective to do, the alignment point 13 to the corner section in order to improve the regeneration of the position is formed, and arranged in front of both sides of support 12 is projected formed flange 10 and the through the imaging scan to the film digitizer for digital radiographic systems by computer-programmed algorithms It characterized in that it can check the non-scattering geurideuyi quality.
