title: [Use of digital technology in x-ray television imaging].
abstract: The questions of decreasing radiation loads in X-ray TV units due to application of digital means of storing X-ray TV images are considered. On the basis of the theoretical analysis of the spatial frequency, time and noise parameters of the X-ray image amplifiers the authors derived expressions relating the input ratio signal/noise of the USSR manufactured URI to the intensity of the X-ray radiation dose of the transformer input. It was established that under the pulse mode of the X-ray unit and storage in the digital memory of the TV unit signal to get the needed ratio signal/noise of the output videosignal (37 dB) it is quite enough to secure on the transformer input the value of the X-ray radiation dose of 15 microR. The functional scheme of the digital unit operating in pulse and pseudodynamic modes of X-ray diagnostic units is outlined.
