Abstract: An x-ray examination installation includes an imaging system having components disposed on opposite sides of a patient on a patient support table. Positioning of the imaging system is coordinated with positioning of the patient support system in that the components of the imaging system are automatically moved, upon positioning of the patient support system, in a direction opposite to the movement of the patient support table. The range of adjustment of the patient support table can be sub-divided into ranges to which separate switching stages are allocated, so that the movement of the imaging system in a direction opposite to movement of the patient support table occurs only within predetermined ranges, so that such movement is not effected when the patient support table is adjusted within a central range.

Abstract: An x-ray diagnostics installation includes an x-ray source, an x-ray image intensifier with a following video chain, a sheet film changer, and a support table for an examination subject. The sheet film changer is mounted on a carriage moveable beneath the patient support table. The x-ray source and the x-ray image intensifier are displaceable together along the support table, and the sheet film changer is positionable by means of the undercarriage in the beam path in front of the x-ray image intensifier, and is couplable thereto so that it follows the movements of the x-ray image intensifier along the support table on its carriage. The installation can thus be optionally used for transillumination or exposure of an examination subject on the table.
