Adaptive X-ray filter for varying intensity of local x-ray used for examining organs, has position elements to displace liquid partly and caps that are connected together in the shape of honeycomb proximate to position elements

The filter (1) has position elements that change the layer thickness of liquid at specific position. The position elements are arranged in the shape of mushroom with cap and stem. The caps are connected together in the shape of honeycomb proximate to the position elements. The liquid is displaced pa...

More Information
Summary:The filter (1) has position elements that change the layer thickness of liquid at specific position. The position elements are arranged in the shape of mushroom with cap and stem. The caps are connected together in the shape of honeycomb proximate to the position elements. The liquid is displaced partly with the movement of the position elements. An independent claim is included for method for varying intensity of local x-ray. Die Erfindung gibt ein adaptives Röntgenfilter (1) und ein zugehöriges Verfahren zur Veränderung der lokalen Intensität einer Röntgenstrahlung (2) an. Das Röntgenfilter (1) umfasst eine erste, Röntgenstrahlung (2) absorbierende Flüssigkeit (3) und hydraulisch bewegbare Stellelemente (8), die die Schichtdicke (9) der ersten Flüssigkeit (3) am Ort des jeweiligen Stellelements (8) verändern, indem sie die erste Flüssigkeit (3) zumindest teilweise verdrängen können. Die Erfindung bietet den Vorteil, dass das Strahlungsfeld einer Röntgenstrahlung einfach, präzise und schnell in zwei Dimensionen moduliert werden kann.
