Abstract
A rotating x-ray anode has an annular focal track. The surface of the focal track has a directed ground structure. Over the circumference of the annular focal track and over the radial extent of the focal track, the alignment of the ground structure is inclined relative to a tangential reference direction in the respective surface portion in each case by an angle that lies in the range from 15°, including, up to and including 90°. A corresponding method for producing a rotating x-ray anode is described.

A rotating x-ray anode, comprising:
- an annular focal track having a surface formed with a directed ground structure;
- an alignment of the directed ground structure, over a circumference of said focal track and over a radial extent of said focal track, being inclined in relation to a tangential reference direction at a respective surface portion by an angle in a range from 15° to 90°, wherein the range includes 15° and 90°;
- and
- wherein the directed ground structure is a surface structuring that is formed by a uniformly distributed array of individual striae or individual grooves that are aligned along a preferential direction, and wherein the individual striae or individual grooves have a randomly distributed arrangement and randomly distributed dimensions.
A method of producing a rotating x-ray anode, the method comprising:
- introducing a directed ground structure into at least a region of an annular focal track of the rotating x-ray anode such that, over a circumference of the annular focal track and over a radial extent of the focal track, an alignment of the ground structure is inclined in relation to a tangential reference direction in the respective surface portion in each case by an angle in a range from 15° to 90°, wherein the range includes 15° and 90°;
- and
- wherein the directed ground structure is a surface structuring that is formed by a uniformly distributed array of individual striae or individual grooves that are aligned along a preferential direction, and wherein the individual striae or individual grooves have a randomly distributed arrangement and randomly distributed dimensions.
