Abstract

An adaptive x-ray filter for changing a local intensity of x-rays includes an x-ray absorbing first fluid and electrically deformable control elements. The electrically deformable control elements change a layer thickness of the first fluid at a site of a respective electrically deformable control element by at least partially displacing the x-ray absorbing first fluid.
