Abstract: The invention relates to a drive unit (12) for vertical or horizontal movement of a component (7) of a diagnostic X-ray device (1), comprising a motor and gear unit (14), a pulley (10) mounted on a drive shaft (13) of the motor and gear unit (14), and traction means (9), e.g. a rope or a drive belt, wound around the pulley (10), the component (7) to be moved being either attached to the traction means (9) or connected with the drive unit (12).

Abstract: The invention relates to a ceiling support system for a movable component (7) of a diagnostic X-ray device (1). The system comprises a horizontally movable carriage (8), a crane (9) attached to the carriage (8), which crane (9) is vertically extensible and contractible by means of telescoping sections (10), and at least one flexible electrical cable (17) for the power supply and/or for the control of the movable component (7). In order to provide such a ceiling support system with improved movability of the X-ray tube and/or the X-ray image detector, the invention suggests that the electrical cable (17) is led from the carriage (8) through the telescoping sections (10) of the crane (9), wherein a cable drum (18) is arranged at the top end of the crane (9) for winding the electrical cable (17) during vertical movement of the component (7).

Abstract: The invention relates to an X-ray examination apparatus which includes a patient table (1), a fluoroscopy image intensifier (61) which is displaceable in the longitudinal direction of the table on a first carriage (6), an overtable X-ray source (2) which is aligned with respect thereto and is coupled to the first carriage, and an image recording means (71) which is displaceable on a second carriage (7). The second carriage can quickly move to a parking position and from this parking position to an exposure position in that the second carriage is displaceable in the longitudinal direction of the table, independently of the first carriage, and in that there is provided a drive system (8,9) which displaces the two carriages in synchronism in a first mode of operation and displaces the second carriage relative to the first carriage in a second mode of operation.

Abstract: An X-ray diagnostic apparatus, includes a table underframe and a base unit for supporting the table underframe which can be swiveled about a horizontal axis, and also includes a displacement device for displacing the table underframe relative to the base unit. The device for swiveling the table underframe is usually a complex construction which is expensive to manufacture. Moreover, the supporting therein is often problematic. Therefore, in a simple construction a first point of a guide rod is arranged at a hinge point on the base unit and a second point of the guide rod is arranged at a hinge point on the table underframe, so that a swiveling motion of the table underframe is imposed upon displacement of the table underframe with respect to the base unit.
