1. A method for aligning a radiographic inspection system, comprising the steps of:

  • providing a radiation source capable of emitting a beam pattern;

    positioning a detector to receive radiation emitted from said radiation source;

    causing said radiation source to emit said beam pattern;

    using said detector to determine the distribution of flux intensity of said beam pattern;

    relatively positioning said radiation source and said detector, so that said detector is disposed at a predetermined location within said beam pattern; and

    moving the detector to a known location relative to the radiation source;

    recording the flux intensity at a plurality of points on the detector; and

    repeating the steps of moving the detector and recording the flux intensity until the recorded flux intensities can be used as a map of the beam pattern.
