Abstract
We propose a new tomographic imaging method based on the multiple Coulomb scattering processes of electrons in the GeV-range. Particle tracking devices are used for a position-resolved measurement of the distribution of scattering angles at a sample. From this, an estimate of the two-dimensional material budget distribution of the sample is extracted. Repeating this measurement for different particle incidence angles enables a reconstruction of the three-dimensional material budget distribution.
To demonstrate the feasibility of this technique, simulations have been performed including the underlying physical processes of charged particles traversing matter, as well as the electronic response of the tracking detectors. We compare two data reconstruction models and discuss the simulation results in terms of the reconstructed image contrast.
