This study presents a two‐laser alignment approach for facilitating the precise alignment of various imaging and measuring components with respect to the x‐ray beam. The first laser constantly pointed to the output window of the source, in a direction parallel to the path along which the components are placed. The second laser beam, originating from the opposite direction, was calibrated to coincide with the first laser beam. Thus, a visible indicator of the direction of the incident x‐ray beam was established, and the various components could then be aligned conveniently and accurately with its help.
