Atomic number estimation of dual energy cargo radiographs using a semiempirical transparency model
Peter Lalor, Areg Danagoulian
Dual energy cargo inspection systems are sensitive to both the area density and the atomic number of an imaged container due to the dependence of photon attenuation. The abilit…
