Abstract: A portable battery powered tool for aligning equipment in an X-ray room includes two spaced apart channel engaging connectors carried by a reference surface of the tool for engaging the usual recessed channels in the ceiling of the X-ray room, a laser carried by the tool for projecting a line in a projection plane parallel to the reference surface and an electronic sensor and indicator carried by the tool for indicating with an array of LEDs whether the projection plane deviates from level along each of two orthogonal axes. The tool also includes adjustment screws for finely adjusting the orientation of the reference surface relative to the ceiling. When mounted to the ceiling and leveled, the tool projects a line on a surface of the rail which projected line is used as a reference for leveling the rail. A stand is provided for the tool to establish a vertical projection plane so as to produce corresponding projected lines on the floor and ceiling.
