METHOD AND APPARATUS FOR INSPECTING QUALITY OF NON-SCATTERING GRID OF DIGITAL RADIATION SYSTEM USING X-RAY FILM AND FILM DIGITIZER

摘要

PURPOSE: A method and an apparatus for inspecting quality of a non-scattering grid of a digital radiation system using an X-ray film and a film digitizer are provided to convert an analog image of an X-ray film to a digital image by using the film digitizer. CONSTITUTION: A fixing frame(10) includes an alignment point and an alignment support unit. The alignment point(13) is formed at a corner part of the fixing frame in order to improve reproduction of an X-ray image. The alignment support unit is projected from both sides of a front side of the fixing frame. A film digitizer is used for scanning the image. The quality of a non-scattering grid of a digital radiation system is inspected by using a programmed algorithm of a computer.
