Monte Carlo simulations for the development a clinical proton CT scanner

In support of developing the next phase of a proton computed tomography (pCT) scanner with features making it applicable to clinical situations, much insight can be gained through Monte Carlo simulation using Geant4. Careful simulation of energy/range detectors, as well as silicon strip detectors (SSDs), has offered insights into the physical limitations placed on a pCT scanner. Simulation also offers the opportunity to evaluate different detector design schemes and regimes for reconstructing CT images using protons.
