  • Patent number: 9312040
    Abstract: An adaptive x-ray filter for changing a local intensity of x-rays includes an x-ray absorbing first fluid and electrically deformable control elements. The electrically deformable control elements change a layer thickness of the first fluid at a site of a respective electrically deformable control element by at least partially displacing the x-ray absorbing first fluid.
    Type: Grant
    Filed: May 21, 2013
    Date of Patent: April 12, 2016
    Assignee: Siemens Aktiengesellschaft
    Inventors: Hans Liegl, Reiner Franz Schulz
  • Patent number: 9263163
    Abstract: An adaptive X-ray filter for varying a local intensity of X-ray radiation includes a first chamber containing a magnetorheological or electrorheological first liquid, a second chamber containing a second liquid that absorbs X-ray radiation, and a flexible membrane that separates the first chamber from the second chamber. Using the flexible membrane, a layer thickness ratio of the first liquid and the second liquid may be varied. A heating apparatus that heats the second liquid is arranged in the adaptive X-ray filter. The second liquid is a liquid metal.

  • Patent number: 9183961
    Abstract: An adaptive x-ray filter and an associated method for changing a local intensity of x-ray radiation are provided. The adaptive x-ray filter includes a first fluid absorbing x-ray radiation and hydraulically moveable positioning elements that change the layer thickness of the first fluid at a location of the respective positioning element by being able to at least partly displace the first fluid.

  • Patent number: 6874934
    Abstract: A modular X-ray diagnostic appliance has as a first module, a base support, as second module, at least one support for the base support, as a third module, at least one component of an X-ray imaging device, as a fourth module, a support device for an object to be examined, and, as a fifth module, a longitudinal carriage which is arranged above the base support and on which the component is mounted. The base support has support-device coupling elements for coupling the support device thereto, support-coupling elements for coupling the support thereto and component-coupling elements for coupling the component thereto. The component-coupling elements have a fixed and/or floating bearing arranged on the base support and connected to the longitudinal carriage. In a method for producing different series of X-ray diagnostic appliances, in which a structurally identical modular base support and a structurally identical modular support device are used for all series.

  • Publication number: 20040091082
    Abstract: A modular x-ray diagnostic appliance is described, having, as first module, a base support (1), as second module, at least one support for the base support (1), as third module, at least one component of an x-ray imaging device, as fourth module, a bearing device (33) for an object to be examined, and, as fifth module, a longitudinal carriage (20) which is arranged above the base support (1) and on which the component is mounted. On the base support, bearing-device coupling elements (31, 32) for coupling the bearing device (33) thereto, support-coupling elements (6) for coupling the support thereto and component-coupling elements for coupling the component thereto are formed, the component-coupling elements comprising a fixed and/or floating bearing (22, 23) arranged on the base support (1) and connected to the longitudinal carriage (20).

  • Publication number: 20040086083
    Abstract: An imaging medical examination apparatus, particularly an X-ray apparatus, has an electric motor for the drive of a movable component. The rotor of the motor is blocked when no drive current is supplied into the electric motor. The electric motor is a sliding rotor motor. The use of a self-inhibiting gearing can be foregone.
