    Abstract: An x-ray generating device having an improved high efficiency motor is disclosed. The x-ray generating device comprises a cathode assembly and an anode assembly arranged opposite each other in a vacuum vessel. According to the invention, the anode assembly is coupled and rotated by the rotor of a high efficiency motor which has near traditional gaps by positioning the motor stator assembly in close proximity to the rotor of the motor and applying a same potential to both the stator core and the rotor. The stator assembly further includes poly-phase stator winding coils arranged on the stator core. The coils are electrically insulated from the stator core, and they are supplied with poly-phase AC signals from a motor controller to induce magnetic interactions and rotate the rotor and the anode assembly. Thus, the present invention provides for electrical isolation between the x-ray operating potential and the reference potential of the motor controller without the need for a separate isolation transformer which negatively impacts cost, efficiency and reliability.

    Abstract: The present invention relates to a rotor for an X-ray tube. In order to provide further possibilities for weight reduction in X-ray tubes for providing an increase of rotation frequency, a rotor (10) for an X-ray tube is provided, comprising a rotational structure (12) with a plurality of electrically conducting elements (14), the ends thereof connected to each other and provided such that an external stator magnetic field generated by a stator induces a current in the electrically conducting elements, which current generates a rotor magnetic field to interact with the stator magnetic field. At least the plurality of electrically conducting elements is made from carbon composite based material.

    Abstract: A cathode assembly including certain features designed to protect the integrity of a filament contained therein is disclosed. In particular, the cathode assembly is configured to prevent damage to the filament should it inadvertently contact another portion of the cathode assembly. In an example embodiment, an x-ray tube incorporating features of the present invention is disclosed. The x-ray tube includes an evacuated enclosure containing a cathode assembly and an anode. The cathode assembly includes a head portion having a head surface. A slot is defined on the head surface and an electron-emitting filament is included in the slot. A protective surface is defined on the head surface proximate to a central portion of the filament. The protective surface in one embodiment is composed of tungsten and is configure to prevent fusing of the filament to the protective surface should the filament inadvertently contact the protective surface.
