X-ray installation has two contours of control (of anode voltage and filament voltage), screen, source of X-ray radiation, collimator, transportation device, block of indicators, crystal, protection screen, photo-sensitive element, block for transformation of current to voltage, switch, analog-digital transformer, device of electronic-calculation processing. Additionally there is includes digital-analog transformer input of which is connected to second output of device of electronic-calculation processing, and the output is connected to the second input of comparison device of circuit for control of anode voltage. |
