“…Depending on the application, an industrial tomography system can be designed in such a way that it can detect micrometer-sized defects in mechanical parts [16], and also it can be designed to recognize a hole with a diameter of several centimeters in the trunk of a tree [17]. Each of these tomography systems needs a compatible detector.…”

Industrial gamma-ray computed tomography systems have found different applications and have become an important tool for non-destructive testing. In this work, high aspect ratio rod plastic scintillators were assessed for use in this type of tomography system. All analyses were performed using Monte Carlo simulation by geant4 toolkit. Validation of the results was done using a 50 cm rod plastic scintillator with a diameter of 5 cm. The results showed that the rod plastic scintillators can be employed in industrial tomography systems for scanning large objects. The spatial resolution of the detection system was estimated more than 1 cm. Finally, the simulated parameters of the selected rod plastic scintillator were compared with an identical NaI(Tl) rod scintillator to find a better understanding about its performance.

“…We also suggested an entirely new industrial tomography system in 2019 [17,22,23] based on using rod shaped scintillators. It was shown that this type of scintillator is inherently positionsensitive and can be employed as linear detectors for gamma/x-ray imaging and tomography purposes.…”
