Resonant neutron attenuation has been shown to be usable for assaying elements which constitute explosives, cocaine, and heroin. By careful analysis of attenuation measurements, the determination of the presentce or absence of explosives can be determined. Simple two dimensional radiographic techniques only given results for areal density and consequently will be limited in their effectiveness. Classical tomographic techiniques are both computationally very intensive and place strict requirements on the quality and amount of data acquired. These equirements and computations take time and are likely to be very difficult to perform in real time. Simulation studies described in this article have shown that laminographic image reconstruction can be used effectively with resonant neutron attenuation measurments to interrogate luggage for explosives or drugs. The design of the system described in this article is capable of pseudo-three dimensional image reconstruction of all of the elemental densities perinent to explosive and drug detection.
