Radiation exposure factors optimization of X-ray digital radiography for watermarked art pottery inspection

Abstract

Non-Destructive Testing (NDT) is a technique for detecting a defect in an object without causing damage. NDT technology can be utilized in the arts for inspection purposes. The NDT technique that can be used for the inspection of art pottery is digital X-ray radiography. It can inspect until the contents inside the art pottery without causing damage. To obtain a high quality of watermarked art pottery image using digital radiography, the radiation exposure factors should be optimized. In this work, optimization was done by varying the voltage, current, and exposure distance. Then, the radiography images were analysed using Contrast to Noise Ratio (CNR). From the analysis, it can be determined that the optimum exposure factors are 60 kV of voltage, 16 mA of current, and 100 cm of exposure distance.

“…Consequently, this results in an increase in the SNR of the resultant image. However, high levels of kV exposure could lead to a reduction in the differential attenuation of the X-ray photons by regions of the part under test with differing thicknesses, thus reducing the CNR between a feature and background [43]. 2.…”
