Abstract

An arrangement for modifying the local intensity of x-ray radiation includes an x-ray filter with a plurality of absorption chambers, which may be filled by a ferrofluid. The absorption chambers are stacked in the x-ray beam direction. The x-ray filter includes a plurality of storage containers in which the ferrofluid may be stored. Each of the absorption chambers is connected to a respective one of the storage containers. The absorption of the x-ray radiation is achieved as a result of individual absorption chambers being filled with the ferrofluid. By filling a different number of absorption chambers, the local intensity of the x-ray radiation may be modified easily, precisely and quickly.
