Abstract:
An apparatus having an x-ray head adjustable in at least three mutually transverse axes for directing x-ray energy from different positions toward a part and sensing the energy from the part, the apparatus comprising:at least one detector for sensing the x-ray energy; a frame for supporting the x-ray head and the detector; an x-axis adjustment mount of the frame operably connected to the head and detector for adjusting the head and detector in an x-axis fore and aft direction; a y-axis adjustment mount of the frame operably connected to the head and detector for adjusting the head and detector in a y-axis lateral direction; a z-axis adjustment mount of the frame operably connected to the head and detector for adjusting the head and detector in a z-axis vertical direction; and at least one fine adjustment mount of the frame operably connected to the head and detector for providing finer adjustments of the head and detector in one of the x, y and z directions than the corresponding one of the x, y and z-axis adjustment mounts to allow the head and detector to be moved rapidly via rough adjustments provided by the one adjustment mount, and to move more precisely via fine adjustments provided by the one fine adjustment mount.
