Abstract: A sealed-off X-ray tube having a convex target surface facing an electron beam source and carried by a rigid support mounted for rotary pivotal motion about a fixed pivot point. A bellows is sealed vacuum tight to the target and to the wall of the tube around the pivot point so that the target, the bellows, and the envelope of the tube form a closed surface. Conduits extend through the pivotal bearing to direct the flow of cooling fluid against the back surface of the target and carry the fluid away. The target surface is spherically convex with a center of curvature at the pivot point. The axis of the target precesses about the axis of the tube but the target does not rotate on its own axis. The target may be moved manually or by motor and with a linear, circular or spiral motion. Because of the curvature of the target, the electron optical forces are substantially unaffected by the precessing motion, and virtually constant X-ray beams radiate through windows of the tube.

Thereby the anode (206) is movable along a z-axis in an oscillating manner, the surface of the anode (206) is oriented oblique with respect to the z-axis, and the control unit (257) is adapted to spatially control the focal spot (255 a) in such a manner that the focal spot moves essentially in a discrete manner between a first focal spot position (106a, 406a) having a first z-coordinate and a second focal spot position (106b, 406b) having a second z-coordinate being different from the first z-coordinate. It is further described a computed tomography system (100) being equipped with the X-ray tube (205) and a method for operating the X-ray tube (205).

Abstract: An X-ray generator is provided using a transmission type target having a long life span, where it is possible to change the point for generating X-rays on the surface of the target while maintaining the vacuum chamber in a high vacuum state. A portion of a vacuum chamber 1 that includes a target 2 is linked to a main body portion 1a of the chamber through a linking member 5 as a movable chamber portion 1b. A fixed anode 12 is provided between the target 2 and the electrode 10 at the final stage from among a group of electrodes 8, 9 and 10 for electrostatically accelerating and converging electrons from an electron source 7 and is fixed to the main body portion 1a of the chamber in order to prevent the form of the electrical field from changing when the movable chamber portion 1b is shifted.
