ABSTRACT:
A parallelogram arm adjustably supports the x-ray source and has one end in a rotary bearing at the carriage, the other end carrying an x-ray tube with a radiation diaphragm. The parallelogram arm can be turned about a vertical axis by means of the rotary bearing, and can be moved in a vertical direction, while the central ray of the x-ray tube retains its direction.In the parallelogram arm between the rotary bearing and the x-ray tube support-mounting, a guide mechanism is arranged which displaces the x-ray tube, pursuant to rotating the parallelogram arm about the vertical axis, such that the sides of the field collimated by means of the radiation diaphragm are parallel-displaced.
