  • Patent number: 5412707
    Abstract: Information on positioning of a patient during x-ray examination is provided by imaging a marker, notably a lead-letter, simultaneously with imaging a patient. Remote-controlled markers are provided attached to separate moveable flat frames. The use of a flat frame makes possible to incorporate an arrangement for remote-controlled position and/or orientation, within the serial film changer without increasing required vertical space. Thus comfortable and easy access for a patient onto the patient table is provided. The motion of relevant frames along guide rails is performed by means of a system of motors, belts or chains and pulleys. The motors are controlled by means of potentiometers and a micro-processor that supplies signals in correspondence with a required motion of a relevant frame. The motors are positioned within the serial film changer and aside of the patient support table. As a consequence restriction of the longitudinal motion of the patient support table is avoided.

  • Patent number: 5014968
    Abstract: A patient table has round surface edges for coupling between a troley and a patient table for the transfer of a table top from the trolley to the patient table. When the patient table is lifted by a table lifting mechanism, the table top is decoupled from the trolley after which the trolley can be decoupled from the patient table so as to be removed. The lifting construction of the patient table enables a large stroke to be made in a vertical direction without giving rise to longitudinal displacement of the table includes top. The patient table a hydraulic displacement mechanism for a longitudinal displacement of the table top; this mechanism can also be operated by hand in the case of emergencies.
