Abstract
An x-ray C-arm device has a C-arm rotatable around an orbital axis proceeding perpendicular to the plane of the C-arm. The C-arm carries an x-ray source and a radiation detector, and the overall center of gravity of the C-arm and the components carried thereby exerts a first torque on the C-arm. A counterbalancing device generates a second torque that at least partially compensates the first torque. The counterbalancing device includes a counterweight that is displaceably coupled to the C-arm by a gearing arrangement.
