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.

A scattered radiation grid for an x-ray imaging is disclosed. In an embodiment, the scattered radiation grid includes alternately arranged layers permeable to x-ray radiation and absorbing x-ray radiation. The layers absorbing the x-ray radiation are formed from an amorphous material. Further, a method is disclosed for using an amorphous metal for the layers of a scattered radiation grid absorbing the x-ray radiation.

The present disclosure relates to generating energy. The teachings thereof may be embodied in methods for burning a reaction gas with an electropositive metal. An method for generating energy may include: supplying a reaction gas and an electropositive metal separately to at least one nozzle; wherein the electropositive metal is selected from alkali metals, alkaline earth metals, aluminum, zinc, mixtures, and/or alloys thereof; burning the reaction gas with the electropositive metal; and coverting the reaction gas before or during burning at least temporarily into a plasma.

A method and an apparatus for filtering radio-frequency electromagnetic beams, in particular x-rays, include a fluid container containing a ferrofluid which at least partially absorbs the electromagnetic beams. A distribution of the ferrofluid within the fluid container can be varied by using an applied magnetic gradient field. An irradiation apparatus and a device for irradiating an object are also provided.
