Simulation Study on X-Ray Radiographic Testing of Welds

Despite the acknowledged advantages that computer simulations can offer to Radiographic Testing, simulation solutions are uncommon in the industry. This paper presents an effective strategy for the simulation of Radiographic Testing techniques using Geant4 Application for Tomographic Emission (GATE), which is a medical imaging software toolkit. Models for X-ray emission, test specimen geometry, radiation interaction with the test specimen, and image receptors were created in GATE. Single Wall Single Image and Double Wall Single Image techniques were set up to evaluate the simulation models. The results showed that GATE can afford a reliable and cost-effective solution in the simulation of radiographic Non-Destructive Testing procedures.
