Progress in Nuclear Scattering Radiography

using conventional techniques of high energy physics, density distributions inside thick bodies can be mapped reconstructing the interaction vertex of charged particles in the GeV region. As compared to X-ray computer assisted tomography, nuclear scattering radiography offers the advantages of being fully three-dimensional and of reducing the overall radiation dose for a comparable image quality; furthermore, a subset of the data that corresponds to elastic interactions allows to measure the hydrogen density distribution in the object which is a unique feature of this method. Preliminary results obtained on a preserved human head are here presented.
