   Abstract:
   Simulation is a valuable tool for designing and evaluating the performance of x-ray imaging systems. In previous work,1, 2 a hybrid computed tomography(CT) and x-ray diffraction(XRD) imaging system was developed for improved identification of threat objects in checked baggage. Through large-scale simulations of this hybrid CT+XRD system, we can investigate the impact of various parameters on system performance. These parameters include multi-energy acquisitions, varying energy resolution, and additional system views. We will report on our findings and evaluate the system performance resulting from these variations of the simulated system as well as discuss how these findings may influence future system design.
