X-Ray Metrology for Quality Assurance
There is considerable current interest in deriving accurate dimensional measurements of the internal ge ometry of complex manufactured parts particularly castings This paper describes an approach to the re construction of D part geometry from multiple dig ital X ray images A novel method for radiographic stereo is described which takes into account the spe cial imaging geometry of the digital X...
متن کاملQuality assessment of conventional X-ray diagnostic equipment by measuring X-ray exposure and tube output parameters in Great Khorasan Province, Iran
Introduction: Regular implementation of quality control (QC) program in diagnostic X-ray facilities may affect both image quality and patient radiation dose due to the changes in exposure parameters. Therefore, this study aimed to investigate the status of randomly selected conventional radiographic X-ray devices installed in radiology centers of Great Khorasan Province, Iran, to produce the da...
