ABSTRACT:
The invention relates to an x-ray image converter for use with an x-ray phosphorescent screen which includes means for scanning the screen with a radiation source, as well as detectors for converting light from the exposed phosphorescent screen into a video signal sequence and a further device for the conversion of this signal sequence thus obtained into a visible picture. For such a converter it is desirable to obtain a simple arrangement which permits an interference-free signal which requires a short processing time (less than 10 sec). The invention provides that the phosphorescent screen is subdivided into a plurality of partial areas and to each of them a detector is allocated, which is interfaced to a memory and means for analyzing the image parts and for generating a composite visible picture. An x-ray image converter according to the invention is usable in particular in medical radiodiagnostics.
