Abstract

Die Erfindung betrifft eine Mikrofocus-Röntgeneinrichtung (2), die eine Röntgenröhre (4), die ein Target (6) aufweist, Mittel zur Beaufschlagung des Targets (6) mit einem Targetstrom und Mittel zur Regelung der Intensität (Dosisrate) der erzeugten Röntgenstrahlung aufweist. Erfindungsgemäß weisen die Mittel zur Regelung der Intensität der Röntgenstrahlung (20) Mittel zur Regelung eines Parameters des Targetstromes, insbesondere der Stromstärke des Targetstromes, auf. Auf diese Weise ist die Intensität der erzeugten Röntgenstrahlung mit hoher Zuverlässigkeit und Genauigkeit regelbar.

The invention relates to a microfocus X-ray device (2) having an X-ray tube (4) having a target (6), means for applying a target current to the target (6) and means for controlling the intensity (dose rate) of the generated X-radiation , According to the invention, the means for controlling the intensity of the X-radiation (20) comprise means for controlling a parameter of the target current, in particular the current intensity of the target current. In this way, the intensity of the generated X-radiation can be regulated with high reliability and accuracy.
