[Optimization of dynamic fuzziness and enhancement of image quality of an URI/230-Amethyst digital image intensifier].

In X-ray diagnostic units, digital image intensifiers with a SSD matrix have recently been used instead of vacuum vidicons. Along with the well-known advantage of SSD matrixes, they fail to reach the capacities of vidicons in transmitting movable images. The authors consider that the way out of this situation is to use recursive filters and arithmetic logic devices.

[The characteristics of digital electron optical systems for x-ray diagnosis].

The paper deals with the specific features of X-ray diagnostic units that have no screen-filming device for film X-ray study, with the requirements for hardware and software of these units. It gives data on specific systems for digital X-ray study.
