Observable analysis for proton computed tomography

Abstract : Proton CT (pCT) nowadays aims at improving hadron therapy treatment planning by mapping the electron density of materials. The main information used is the energy of the protons. However, during a pCT acquisition, the spatial and angular deviation of each particle is recorded and the information about its transmission or not is implicitly available. The potential use of those observables in order to get information about the materials is being investigated. Monte Carlo simulations of protons in an homogeneous cube of material and of a pCT acquisition have been performed. Preliminary results indicate that information of interest could be found in the transmission and deviation of the particles.
