Abstract: A rotating anode X-ray tube is provided which includes an anode disk having a central axis of rotation and a circumferential peripheral edge lying in a plane perpendicular to that axis of rotation. A ring-shaped target is mounted to the disk adjacent the peripheral edge and the disk includes a mechanism formed integrally solid with the disk and remote from the target for mounting the disk to a support shaft of a rotor within a vacuum housing to permit rotation of the disk about the axis of rotation of the disk. The disk is formed integrally solid along the aforementioned plane, including that portion of the disk coincident with the axis of rotation and the disk has a thickness which increases progressively in a radially inward direction from the peripheral edge, including that portion of the disk between the target and the mechanism for coupling, to counteract a radially inward increase in the disk upon high speed rotation of the disk. A cathode is provided for bombarding the target with thermions to generate X-rays which escape the vacuum housing through an appropriately placed X-ray penetrable window.

Abstract: An X-ray tube generally comprises an evacuated tube envelope fabricated primarily of metal and having first and second end walls and a cylindrical sidewall, and encloses a rotating anode with its target surface facing the second end wall. A heat transfer sleeve extends from the first end wall past the anode to receive heat from the anode and transfer it to the end wall for dispersal. A heat transfer cross plate at the end of the sleeve further encloses the anode to receive and transfer heat. The tube envelope is mounted in a cylindrical tube housing with the first end wall in contact with a finned mounting plate for dissipating heat. The surface of the tube envelope remains sufficiently cool to apply a layer of lead, whereby the tube is compact. The anode and cathode electrical feeds are through the second end wall. The electrical feeds have angled terminations with lead on them.

Abstract: Die Erfindung betrifft einen Antrieb für die Drehanode (151) einer Drehanoden-Röntgenröhre, welche in einem Wirkungsbereich eines Magnetresonanztomographen (MRT) verwendet wird. Der Antrieb arbeitet nach dem Prinzip eines Elektromotors, bspw. eines Gleichstrommotors, bei dem ein stromdurchflossener Leiter (155) in einem magnetischen Statorfeld eine Lorentzkraft erfährt, die in eine Drehbewegung umgesetzt wird. Der Antrieb der Drehanode weist keine eigenen Komponenten zur Erzeugung eines solchen magnetischen Statorfeldes auf, sondern es wird das Grundmagnetfeld BO des MRT als Statorfeld verwendet.

Abstract: PURPOSE:To make variable the distance of a filament from the target by a method in which a magnetic supply device able to keep a rotor magnetically free-rotatable and free-movable in the axial direction is provided inside the rotor in order to control a state of magnetism for moving in the axial direction. CONSTITUTION:When a control signal is dispatched from a control device 27, a power source of an electromagnet power source 28 changes while a current inside the electromagnet coils 13 and 14 for axial control changes. Accordingly, when magnetism of the magnetic paths S1 and S2 changes, the rotor 6 moves axially while the distance of a filament from an anode disc 5 changes. Said changed position is detected by an axial position detector 22. When the signal of said detector 22 is computed by a control device 27 to find the prescribed position, the current of the electromagnet power source 28 changes while the rotor 23 moves axially to set the desired distance of the filament from the target 5.
