Abstract:
1. An X-ray device, comprising: an X-ray tube configured to emit a beam of X-rays along an emission direction; an X-ray detector situated opposite the X-ray tube and in the emission direction; a C-shaped arm configured to enter into rotation around an axis of rotation, the arm assuring a displacement of the X-ray tube and the X-ray detector in space; a rotating lift connected to the C-shaped arm and having a rotating movement within the C-shaped arm, wherein the rotating lift has an end connected to the X-ray detector or to the X-ray tube, wherein the rotating movement of the rotating lift raises and lowers the X-ray detector or the X-ray tube in the emission direction; and a compensation system coupled to the rotating lift, the compensation system comprising a mechanical component configured to translate the rotating movement of the rotating lift into translational movement, wherein the translational movement keeps the X-ray tube or the X-ray detector aligned with an alignment line when the lift rotates within the C-shaped arm, and wherein the alignment line passes through a focal point of the tube, an isocentre of the device, and the middle of the detector.
