“…In our simulation, we focus on photonic properties of scintillation detector. It is essential to design the physics and mathematics model of X-ray detection at first, and then we utilize a Monte Carlo software (EGS) to analyze characteristics of interaction between X-ray photons and scintillation crystals [17][18][19][20][21][22][23][24][25][26]. In this paper, we study three scintillation crystals CsI(Tl), NaI(Tl), and CdWO 4 ; the physical properties of the three scintillation crystals are shown in Table 1.…”

“…In order to study how to keep enough X-ray energy deposition in CsI(Tl), NaI(Tl), and CdWO 4 scintillation crystals and transform more X-ray photons into visible light photons to obtain high spatial resolution of CT images in industrial X-CT system, it is a reasonable scheme to simulate the photonic properties of CsI(Tl), NaI(Tl), and CdWO 4 scintillation crystals using Monte Carlo (MC) method [17][18][19][20][21][22][23][24][25][26]. Monte Carlo (MC) methods are stochastic techniques, which can be used in nuclear physics to analyze interaction between X-ray photons and scintillation crystals.…”

Currently industrial X-CT system is designed according to characteristics of test objects, and test objects determine industrial X-CT system structure, X-ray detector/sensor property, scanning mode, and so forth. So there are no uniform standards for the geometry size of scintillation crystals of detector. Moreover, scintillation crystals are usually mixed with some highly toxic impurity elements, such as Tl and Cd. Thus, it is indispensable for establishing guidelines of engineering practice to simulate X-ray detection performances of different scintillation crystals. This paper focuses on how to achieve high efficient X-ray detection in industrial X-CT system which used Monte Carlo (MC) method to study X-ray energy straggling characteristics, full energy peak efficiency, and conversion efficiency of some scintillation crystals (e.g., CsI(Tl), NaI(Tl), and CdWO4) after X-ray interacted with these scintillation crystals. Our experimental results demonstrate that CsI(Tl) scintillation crystal has the advantages of conversion efficiency, spectral matching, manufacturing process, and full energy peak efficiency; it is an ideal choice for high efficient X-ray detection in industrial X-CT system.
