摘要
In the illustrated embodiment an electronic transmission channel for converting an X-ray image into a television signal has an illumination device arranged in the optical path leading to the television pickup tube for providing a weak diffuse illumination of the target of the television pickup tube. It is found that such illumination enables the use of a television pickup tube having an cadmium-selenide layer, for example, without the buildup of negative potentials during scanning of the target in the absence of an X-ray image. The illumination device may be formed by one or more luminescent diodes.
