ABSTRACT:
A method for aligning a X-ray beam collimator to a linear array X-ray detector. The method computes a horizontal centerline on the detector and a horizontal centerline the collimator. The horizontal centerlines are then aligned. Vertical centerlines are computed for the detector and collimator. A thickness for a shim is computed from the difference in the vertical centerlines. The collimator is installed on vertical standoffs with the shims inserted between the collimator and standoffs. The shims align the collimator and detector in the vertical direction.
