Abstract
An x-ray and/or gamma radiation absorbing slat, for use in an anti-scatter grid having a layer configuration, includes a film-shaped substrate of a metallic material on the basis of at least one heavy metal and at least one coating layer of a material on the basis of at least one metal from the group tin, antimony, tantalum, tungsten, rhenium, iridium, platinum, gold or bismuth. The material of the coating layer differs from the material of the film-shaped substrate. An anti-scatter grid for x-ray and/or gamma radiation, a method for producing an x-ray and/or gamma radiation absorbing slat and a method of producing an anti-scatter grid, are also provided.
Claims11
A slat for absorbing at least one of x-ray or gamma radiation in an anti-scatter grid having a layer configuration, the slat comprising:
- a film-shaped substrate of a molybdenum-based material;
- and
- at least one coating layer of a tungsten-based material.
A method for producing a slat for absorbing at least one of x-ray or gamma radiation, the method comprising the following steps:
- producing a film from a molybdenum-based material;
- coating the film with a tungsten-based material;
- and
- cutting the film to size in strip shape.
A method of producing an anti-scatter grid, the method comprising the following steps:
- producing slats in a layer configuration for absorbing at least one of x-ray or gamma radiation;
- providing each slat with a film-shaped substrate of a molybdenum-based material;
- and
- providing each slat with at least one coating layer of a tungsten-based material.
