Abstract
A mechanism for mounting a detector head including a collimator which comprises a supporting structure having a single trunnion axis for the detector head. A shifting mechanism is provided for shifting the detector head and the supporting structure with respect to each other in a manner that the detector head including the collimator is balanced with respect to the single trunnion axis. For overall balancing purposes the supporting structure also comprises a counterweight for the detector head secured to a detector head support arm and a device for varying the position of the center of gravity of the counterweight with respect to a joint moveably supporting the arm.
