X-ray diagnostic installation with an image intensifier TV chain and a dose rate control device

Patent:

Abstract

The person performing the examination can key up the dose rate briefly via the X-ray tube current, e.g., if the movement of a contrast medium is to be observed on the video screen and only certain phases in this movement, which are of diagnostic significance, are to be viewed more closely. The upward change necessary to reduce quantum noise by a certain factor is made by means of a switch. This at the same time results in a reduction of brightness (over-exposure) of the X-ray image on the video screen by actuating an aperture system between the image intensifier, and the TV camera. To prevent the X-ray tube from being overloaded during key-up of the dose rate, a time limit switch is installed in the control system.
