Abstract

A filter system is for the local attenuation of X-radiation. In an embodiment, the filter system includes a filter device, arranged in a beam path of an X-ray apparatus and including a channel arrangement, the channel arrangement including a multiplicity of channel sections extending in parallel on a plane; a supply device to provide a 2-phase fluid flow containing drops of an absorber liquid, to absorb X-radiation and a carrier liquid transparent to X-radiation; and a sorting section, including an input connected to the supply device, a first output connected to the channel arrangement, a second output, and a deflection device to direct individual drops of the absorber liquid to the first output or the second output.
