Abstract

Abstract Translated from German Die Erfindung betrifft eine Röntgendiagnostikgerät mit Stellmitteln (19, 20) zum Verstellen jeweils eines einer Mehrzahl von Strahlenfiltern (19a) in den Strahlengang (18). Es sind Mittel (7, 10, 11) zur Bildung eines elektrischen Dichtesignales vorhanden, das von der Dichte des Untersuchungsobjektes (3) abhängt. Die Stellmittel (19, 20) enthalten einen von einer Steuerschaltung (16, 22) angesteuerten Elektromotor (20), der das Dichtesignal zugeführt wird und die den Motor (20) dem jeweiligen Dichtesignal entsprechend zur Auswahl des zugehörigen Filters (19a) ansteuert. The invention relates to an X-ray diagnostic device with adjusting means (19, 20) for adjusting one of a plurality of radiation filters (19a) into the beam path (18). Means (7, 10, 11) are provided for forming an electrical density signal, which depends on the density of the examination object (3). The adjusting means (19, 20) contain an electric motor (20) controlled by a control circuit (16, 22), to which the density signal is supplied and which controls the motor (20) according to the respective density signal for the selection of the associated filter (19a).
