Paper Abstract

In the United States, as well as in Germany, England, and Japan, a limited effort was devoted during the last twenty years to the development of solid state radiographic converters (Ref. 1), which could replace the fluoroscopic screen or the radiographic film. In spite of the fact that the developed converters had some very attractive characteristics, they did not find routine applications in radiographic work (Ref. 2). One reason for this was that some characteristics, as the resolution, the speed and the sensitivity were not satisfactory for a wide application.Another reason was that a vacuum type X-ray image intensifier, which was developed earlier (Ref. 3), gained a widespread application, principally in medical radiology. However, as the work on solid state converters continued, their characteristics were improved so that they can advantageously be used in special applications (Ref. 4 and 5). In the following the working principles and the present state of the radiographic converter screen will be described.
