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.
