Automatic dose power regulator for an X-ray apparatus with an image intensifier
Creators
Description
The invention relates to an automatic dose power regulator for an X-ray radiographic instrument with an image intensifier. In existing versions, it is very difficult to amplify the photocathode signal because of the attending zero shift. Moveover, the time constant of the circuit is not compatible to the variation rate of the mean direct current level. The aim of the invention is to provide such a regulator that by-passes these disadvantages. For that purpose the regulator is equipped with a synchronisation output, that gives a signal proportional to the alternating voltage and that is connected with the control input of a gate circuit.
