Evaluation of CsI(Na) rod scintillator application in industrial gamma-ray computed tomography

摘要

The objective of this paper was to investigate a detection system based on a CsI(Na) rod scintillator for the use in industrial gamma-ray computed tomography. For this goal to be achieved, a CsI(Na) rod scintillator was first grown using the Czochralski method. The scintillation response of the rod scintillator was then assessed. Furthermore, the detection system was employed to determine the positions and energies of incident gamma-rays in a tomography system. Two different phantoms were also constructed to assess the basic characteristics of the system. Results showed that the proposed tomography system has a good performance in industrial applications.
