Scanning head consist of • x-ray tube • Illumination beam collimator • Detectors to measure the backscatter signal 07/22/2010 | 8 • Low z materials typical to aircraft suited to backscatter • Many NDE inspections at known locations and depths • Ability to image through multiple layers • Continuous contact with nested layers not required as with other NDE techniques Conclusions 07/22/2010 | 15
