An X-ray stand includes a fixture attached to the ceiling surface floor surface or side wall surface of a hospital room. A support is connected to the fixture with a rotary bearing connected to a circular track. An arcuate carriage sliding in the track has a radiation source and receptor respectively at its ends which are aligned on a radiation axis through a patient position. The rotational axis of the bearing is inclined at a substantial angle to the fixture and to the wall to which the fixture is attached so that, when the one end of the arcuate carriage is in a position near the ceiling or other wall, rotation around the bearing axis will rotate the radiation axis through substantially different angles through the patient position.
