Abstract

Ein Konturenkollimator (1) weist eine Mehrzahl von in einem Führungsblock (10) vorgesehenen, relativ zueinander verschiebbar angeordneten plattenförmigen Blendenelementen (101, 102, 103, ...) zur Bildung einer konturierten Blende für ein von einer Strahlenquelle (12) ausgehendes, auf den Kollimator gerichtetes Strahlenbündel (13) mit zumindest einem Antriebsorgan zur Verschiebung der Blendenelemente auf. Jedem Blendenelement (101, 102, 103, ...) ist ein Antriebsorgan (111, 112, 113, ...) zugeordnet, wobei die Antriebsorgane einer Gruppe von Blendenelementen im wesentlichen einander benachbart angeordnet sind. Zwischen jedem Antriebsorgan (111, 112, 113, ...) und dem zugeordneten Blendenelement (101, 102, 103, ...) ist eine Antriebsübertragungseinrichtung vorgesehen.
