| 摘要 |
The invention describes an X-ray source in which a cooling plate ( 36 ) for water-cooling the anode ( 28 ) of an X-ray tube ( 26 ) is firmly mounted on a radiation protection casing ( 20 ) and the X-ray tube ( 26 ) is rotatably borne relative to the cooling plate ( 36 ) in the radiation protection casing ( 20 ). The cooling plate ( 36 ) and X-ray tube ( 26 ) have small axial play with respect to each other, which allows for rotation. Radial seals (R 1, R 2 ) ensure adequate sealing of the cooling water throughout the entire axial play. Advantageously, a sealing plate ( 27 ) for adaptation to the cooling plate ( 36 ) is attached to the X-ray tube ( 25 ). With the X-ray source in accordance with the invention, it is easy to switch between various focus types in one casing structure.
