Abstract
In an exemplary embodiment, an x-ray tube is mounted on a tube support arm carried on a separate tube stand. A layer rod releasably couples with the tube support arm for the purpose of aligning the x-ray tube relative to a displaceable radiographic installation on the underside of the patient support platform. The tube need not always be aligned relative to such radiographic installation, but may be aligned, according to requirements, relative to a second radiographic installation. In order to facilitate such change of alignment, the disclosure provides that the layer rod may be placed in a loosely coupled state relative to the tube support arm, and that it bears coupling surfaces which are capable of being brought into positive locking engagement with the tube support arm to effect automatic reorientation of the x-ray tube (without prior manual alignment of the x-ray tube to the radiographic installation) during recoupling operation. The x-ray examination apparatus is particularly suited for utilization in the case of diagnostic x-ray examination apparatus.
