Abstract：
Material discrimination by high-energy (1—10MeV) X-ray dual-energy imaging is investigated in this paper, and an approximately linear model is also proposed. The sensitivity of material discrimination is defined to evaluate the effect of material discrimination. The energy ranges of dual-energy X-ray are optimized by analyzing the X-ray attenuation coefficients after the X-ray penetrate the materials. The sensitivity of material discrimination can be improved by modulating the X-ray energy spectrum with filters. A prototype emitting alternating dual-energy X-ray with 9MeV {\&} 6MeV boundary energies is designed. It can present us the tinctorial images with the material discrimination information. Finally, the experimental results we made agree with the theoretical simulation.
