The imaging means () are arranged movable within the O-arm (). A positioning support () is arranged in connection with said examination opening () whose location with respect to the O-arm () is arranged adjustable. Preferably the apparatus comprises a control system comprising a control function for moving the positioning support () in a first direction at a first speed within the area of the examination opening () and for simultaneously moving the O-arm () with respect to its support construction () substantially at said first speed in substantially opposite direction than said first direction.
