ABSTRACT:
A sheet beam x-ray source having energy components greater than 1.02 Mev is passed through an object under study. The emitted gamma rays due to pair production are measured using a positron-sensitive coincidence counting system on either side of the excited section. The location of each detected event is made using the positron information of each detector and the location of the excited section. An image is rapidly formed which is sensitive to the atomic number and density of materials in the cross section of the object.
