Increasing Penetrating Power of Digital Radiography Systems Based on Analysis of Low-Intensity Signals

A mathematical model of the formation of high-energy digital radiographic images in conditions of low levels of digital signals has been developed. The model is designed to increase the efficiency of the analyzed systems in relation to the testing of large-sized objects by virtue of digital summation of images. Based on the model, an algorithm and a MathCad program designed to simulate digital images of test objects have been developed. Based on the analysis of the results of computational and field experiments, the principal possibility of increasing the efficiency of high-energy digital radiography systems based on accounting for rare events is illustrated.
