Schaefer, M. Prokop, M. Truss, J. Oestmann, S. Reichelt, M. Galanski, U. Jonas] Summary: A digital-projection radiography system with potential applications in genitourinary imaging is presented. The system replaces the traditional film-screen combinations by storage phosphor screens but continues to use cassettes in conventional X-ray equipment. Technical features such as consistently optimal image brightness and contrast across an extremely wide exposure range and edge-enhancement capabilities overcome deficiencies seen with conventional film-screen systems, such as improper exposure and poor contrast discrimination. Images obtained with a dual-energy radiation spectrum selectively demonstrate soft-tissue- or bone-equivalent structures and diminish the obscuring effect of bowel gas. Problems resulting from the singular reliance on film as a display and storage medium in conventional radiography are resolved in digital radiography by fast and simultaneous electronic access to images that can be displayed on high-resolution monitors or laser-printed films. The basic technical features of storage-phosphor digital imaging as compared to conventional radiography are described. A summary of recently published results relevant to genitourinary examinations is given and radiographic examples are presented. Springer-Verlag, 1990 Schaefer C.
