  • Publication number: 20240397601
    Abstract: A two-phase cooling system for an X-ray high-voltage generator comprises a heat sink block and a heat sink. The heat sink block spatially surrounds a cooling duct loop, wherein the cooling duct loop is at least partially filled with a working medium and is configured to act as an oscillating heat pipe. The heat sink is configured to dissipate heat from a heat source. The heat sink block includes a material including a polymer.

  • Publication number: 20230411107
    Abstract: A brushless drive system includes a reluctance rotor and a stator for generating a magnetic flux. The stator has a cylindrical stator yoke, an annular permanent magnet and a coil unit. The reluctance rotor has a cylindrical rotor yoke that is made of a soft-magnetic material, is free from magnetic sources and is configured to be driven about an axis of rotation via the magnetic flux. The permanent magnet and the coil unit are axially spaced apart along the axis of rotation. The stator yoke, the permanent magnet, the rotor yoke and the coil unit form a magnetic circuit for guidance of the magnetic flux. The magnetic circuit is configured such that, between the permanent magnet and the coil unit, an axial direction of the magnetic circuit in the stator yoke and an axial direction of the magnetic circuit in the rotor yoke have opposite signs.

  • Publication number: 20230387744
    Abstract: A gantry drive includes a multiphase stator, a multiphase rotor, a tunnel-shaped cavity configured to receive a patient, and a controller. The multiphase rotor spatially surrounds the cavity. The multiphase stator and the multiphase rotor form a multiphase motor configured to produce a rotating-field power. A first portion of the rotating-field power provides a mechanical drive power to produce a rotational movement of the multiphase rotor, and a second portion of the rotating-field power provides an electrical supply power for a payload apparatus. The controller is configured to vary at least one of the first portion or the second portion.

  • Publication number: 20220338832
    Abstract: In a method for regulating a position of an X-ray focus on the anode of an X-ray source of a scan unit of an X-ray imaging system, a combined actual position of the X-ray focus is determined by a combination of a measured position of the X-ray focus and a model-based position of the X-ray focus, which is determined based on a measured value of a deflection current. On the basis of the combined actual position and a target position, a manipulated variable is determined. On the basis of the determined manipulated variable, a regulation is performed to correct a deviation of the position of the X-ray focus from the target position.

  • Publication number: 20180261420
    Abstract: An X-ray emitter includes an anode rotatably mounted arranged inside a vacuum housing. It can be set into rotation by an electric drive. In the region of a focal spot, the anode can be exposed to an electron beam emitted by a cathode. According to an embodiment of the invention, a control unit is configured to activate an electromagnetic deflection unit that deflects the electron beam as a function of at least one operating parameter of the electric drive such that a movement of the focal spot, caused by electromagnetic fields of the electric drive, can be at least partly compensated for. An embodiment of the invention further relates to a method for compensating for a focal spot movement when X-ray emitters in operation.

  • Publication number: 20130141182
    Abstract: A device for improving the filter effect of a filter connected up between an electrical energy source and a source of interference is provided. The filter is configured to feed back interference transients from ground to an input of the source of interference generating the interference transients. The device includes a measuring device for determining a leakage current flowing through the filter and a final control element configured to modify a limit frequency of the filter such that the leakage current through the filter is damped to below a predefined level if the measuring device detects the leakage current.
