Abstract
A bridge plate mounted on the top of an x-ray spot filmer has an opening for passing an x-ray beam and several pads adjacent the opening. Each pad has a threaded hole. A ring member which supports an x-ray image intensifier on its top side has a plurality of planar areas on its bottom side which interface with the respective pads. Each planar area is under a recess on the top side of the ring member. When cylindrical washers are placed in the recesses and machine screws are passed through the washers and turned into the threaded holes of the pads, the centers of the spot filmer and the image intensifier and the focal spot of the x-ray tube are established on a common axis. Locators cooperate with the ring member to remember its location. The washers are supplanted with cam elements which can be rotated manually to shift the ring member multilaterally for reestablishing its position relative to the locators when the ring member is being restored to the bridge plate following disassembly of the intensifier from the spot filmer.
