Summary: | The adaptive X-ray filter (1) has an electrically deformable position element which changes the layer thickness of the X-ray radiation absorbing liquid at the location of the position element by displacing the X-ray radiation absorbing liquid. The position element is arranged in a plane vertical to X-ray radiation (2). A flexible diaphragm portion is provided to separate the radiation absorbing liquid from the position element. The position element is provided with an electro-active polymer portion. An independent claim is included for a method for altering local intensity of X-ray radiation with adaptive X-ray filter.
Die Erfindung beansprucht ein adaptives Röntgenfilter zur Veränderung der lokalen Intensität einer Röntgenstrahlung. Das adpative Röntgenfilter (1) umfasst eine erste eine Röntgenstrahlung (2) absorbierende Flüssigkeit (15), beispielsweise Galinstan, und elektrisch verformbare Stellelemente (17), die die Schichtdicke der ersten Flüssigkeit (15) am Ort des jeweiligen Stellelementes (17) verändern, indem sie die erste Flüssigkeit (15) zumindest teilweise verdrängen. Die Erfindung bietet den Vorteil, dass durch das adaptive Röntgenfilter (1) das Strahlungsfeld einer Röntgenstrahlung (2) einfach, präzise und schnell moduliert werden kann. |
