Development of an industrial computed tomography designed with a plastic scintillator position sensitive detector

摘要

An industrial computed tomography (CT) using the plastic scintillator (PS) as a detector sensitive to the radiation interaction position was proposed. Firstly, a code using Monte Carlo method was developed to study the effects of the plastic scintillator geometry in its gamma ray detection. The software simulates the results system designed with two photomultiplier-tubes set up in coincidence. Four simulations sets were performed to foresee the effect of the diameter (5-50 cm) and length (1-128 cm) of the detectors. The plastic scintillator was designed to be used for the industrial tomography system application. The Monte Carlo developed code was validated for its use to foresee the suitable dimension of the scintillator detector and some geometrical aspects.
