ABSTRACT:
An x-ray examination apparatus has an x-ray image intensifier and an x-ray film changer mounted so that the x-ray film changer can be moved to an exposure position, in front of the x-ray image intensifier, for producing x-ray pictures of an examination subject. The x-ray image intensifier has a holder on which the x-ray film changer is movably mounted so that, when in the exposure position, the film changer has the same image axis as that of the x-ray image intensifier. The film changer is pivotable out of the exposure position by approximately 90.degree. to a standby position. To avoid having the x-ray film changer in the standby position prevent access to a patient on an examination table, and to permit the x-ray image intensifier to be adjusted to any arbitrary position without being impeded by the film changer in the standby position, the examination apparatus has a holder for the film changer in the form of a bearing which at least partially surrounds the x-ray image intensifier. The bearing is disposed in a plane which is substantially perpendicular to the image access, and the film changer is displaceable along the bearing.
