Abstract

X-ray apparatus comprises a U-shaped support having two hollow, horizontal arms. On the end of one arm is mounted an X-ray tube and on the other an X-radiation receptor both guided for movement on a radiation axis. A counterweight within one hollow, horizontal arm is guided for movement parallel to the X-ray tube, transversely of the arm. To counterbalance the X-ray tube a lever attached to the tube has sliding pivots at a fulcrum and the counterweight allowing the lever arm to change its length without changing the leverage ratio.
