ABSTRACT:
A contraband detection system using a cone beam computed tomography scanner. The cone beam scanner allows for rapid acquisition of data for computing three dimensional density maps of objects within items under inspection. Where greater resolution is desired, the image information obtained with the cone beam computed tomography scanner may be combined with higher resolution images formed with a single view scanner. A multi-energy single view scanner may be used to additionally provide information on the effective atomic number of objects contained within items under inspection. Additionally, information obtained with the cone beam computed tomography scanner may be used to increase the accuracy of the computation of the effective atomic number of objects within the item under inspection.
