A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well.

Rotary anode for a rotary anode X-ray tube and method for manufacturing a rotary anode

The invention relates to a mounting device for mounting a beam manipulating device of an X-ray apparatus to a radiation source of the X-ray apparatus, said mounting device comprising a first mounting flange () associated with the radiation source, a second mounting flange () associated with the beam manipulating device, and fastening means () for fixing the first mounting flange () and the second mounting flange () to each other. It is an object of the invention to facilitate the alignment of the X-ray beam manipulating device with respect to an X-ray beam path or an X-ray beam focus of the radiation source. To achieve this, the alignment means () are adapted to be fastened to the first mounting flange (), the first mounting flange having a first reference surface () which is in a predetermined spaced relationship with respect to the X-ray beam path. The first reference surface () corresponds with a second reference surface () of the second mounting flange (). Furthermore, the invention provides a method for mounting a beam manipulating device to a radiation source of an X-ray apparatus.

Pre-adjustable mechanical collimator interface

The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing which is composed of an inner and an outer bearing segment, the outer bearing segment including intermediate pieces and a holder on which the intermediate pieces bear so as to transfer the bearing forces. Suitable shaping of the external surfaces of the intermediate pieces and the inner surfaces of the holder which contact these outer surfaces ensures that the intermediate pieces become aligned with the bearing surfaces on the inner bearing segment. This strongly reduces the complexity of manufacture.

Rotary-anode X-ray tube provided with a hydrodynamic sleeve bearing

The invention relates to an X-ray apparatus, including an apparatus section which is pivotable about a horizontal pivotal axis that does not extend through its center of gravity, and a spring assembly for compensation of the torque which is exerted by the weight of the apparatus section on a coupling member which moves in an orbit about the pivotal axis during pivoting of the apparatus section. Suitable counterbalancing is readily achieved in that the center of the orbit is situated outside the pivotal axis in a vertical plane containing the pivotal axis and that the coupling member is guided in a guide device which is connected to the apparatus section and which extends towards the pivotal axis.
