[Roentgenologic converters for medical radioscopy].
Peculiarities of use of luminescent and semiconductor converters of X-radiation in radioscopy are examined. Characteristic features of X-ray devices (electro-optical transducers, X-ray vidicons, gas discharge and luminescent converters), based on the use of luminescent and semiconductor converters are comparatively analyzed. Estimation of X-ray image quality is given. Use of gas discharge and luminescent converters is found to be the most prospective for medical radioscopy. The aforementioned converters are distinguished by high dose sensitivity, simplicity of the construction and greater size of working field.
Equipment Design↗
[Digital x-ray television unit with solid-state memory].
A digital memory and a control unit are described that along with the pulse X-ray TV diagnostic system enable reduction of the exposure dose in the course of X-ray examinations. Diagnostic capabilities of the system are improved due to possibility to view up four images at various examination angles at the display and to scale every image.

[Digital synthesis of x-ray diagnostic images].
Main features of digital processing of X-ray images are analysed. A preferable algorithm of the image synthesis is built. The contrast control of visual images has been shown to result in improved informativity of roentgenograms.
