Abstract

An x-ray diagnostics installation has an x-ray source, an x-ray image intensifier connected to a video chain and a processing circuit which controls various components of the installation. The processing circuit includes a weighting circuit which allocates an individual weighting factor to different regions of the x-ray image. The processing circuit also includes an evaluation circuit, connected to the weighting circuit, which combines the signals from the weighted image regions to form an actual value signal, which is used to control certain of the components of the installation.
