Shielding mask for scattered ionizing radiation and method for production thereof

An imaging x-ray device, comprising

• an x-ray detector configured to detect x-radiation;
• an x-ray source;
• and
• a shielding mesh between the x-ray detector and the x-ray source, wherein the shielding mesh comprises:
• a plate having a first side and a second side opposite the first side;
• an arrangement of depressions in the plate that are open toward the second side;
• a mesh of trenches in the plate that are open toward the first side;
• and
• an x-ray-absorbing material in the mesh of trenches, wherein the mesh of trenches and arrangement of depressions are configured so that a wall of the plate remains between the arrangement of depressions and the mesh of trenches.

A method of producing a shielding mesh to counter scattered x-radiation, comprising:

• providing a plate having a first side and a second side opposite the first side;
• irradiating the plate with a laser beam, the material of the plate being is transparent to the laser beam such that the laser beam penetrates into the plate and causes a first group of filamentous damage on the first side;
• irradiating the plate with the laser beam such that the laser beam penetrates into the plate and causes a second group of filamentous damage on the second side;
• removing material of the plate in the region of the second group of filamentous damage by etching the plate with an etch medium so that an arrangement of depressions open toward the second side of the plate are formed;
• removing material of the plate in the region of the first group of filamentous damage by etching the plate with the etch medium so that a mesh of trenches open toward the first side is formed;
• and
• introducing an x-ray-absorbing material into the mesh of trenches.
