  • Patent number: 6382832
    Abstract: The invention relates to an X-ray examination apparatus which can be universally used for X-ray fluoroscopy and X-ray exposures. It includes a tiltable patient table, a horizontally displaceable stand on which an X-ray source is mounted so as to be vertically displaceable, and a coupling member which couples the stand or the X-ray source to the image converter arrangement provided in the patient table. Depending on the type of coupling, either X-ray fluoroscopy and Bucky exposures or slice exposures are possible. Furthermore, other exposure modes can be performed when the stand is decoupled from the coupling member.

  • Patent number: 5497408
    Abstract: An X-ray examination apparatus, including a patient table which is pivotable about a first axis, a spot film device which is arranged over the table top of the patient table and which is displaceable parallel to the table top by means of a transport device, and also an X-ray source which is coupled to the transport device in order to form an X-ray beam. The use of the X-ray source, either underneath the table top for use with the spot film device, or over the table top for overtable X-ray exposures, positioning is possible in that the X-ray source is pivotable about a second axis which is connected to the transport device and which extends parallel to the first axis.

  • Patent number: 4602157
    Abstract: The invention relates to an X-ray image recording device which comprises so-called latent image storage means which are capable of storing an image which, after stimulation can be sequentially read out in a read-out station, followed by erasure in an erasing station, so that the same image storage means can be used again. The image storage means is provided on the side surface of a preferably prismatic body which can be rotated to three different positions in which the image storage means can be exposed, read-out and erased, respectively.

  • Patent number: 4523420
    Abstract: The invention relates to an X-ray examination apparatus comprising a light-tight film processing section with one or more film storage magazines. A film sheet can be removed from the magazine in order to be transported to the exposure position. The apparatus also comprises a cassette loading and unloading station as well as a film guide device. A film sheet can be transported by the film guide device either into the beam path at the exposure position or into a cassette in the cassette loading and unloading station. Thus, cassette exposures can also be made without loading and unloading the cassette in a separate dark room or without a so-called daylight system being necessary.
