Summary:Title screen
A mathematical model has been developed for digital radiographic imaging of large-sized objects. The model takes account of scanning time, the parameters of source and recorder of bremsstrahlung due to the test object, and geometrical scanning scheme. A high-performance algorithm is proposed for the numerical modeling of digital radiographic images. The algorithm has allowed producing realistic images of large-sized stepped and wedge-shaped test objects and test objects typical of pipeline transport. The rationale for selecting the scanning time and the digit capacity of an analog-to-digital converter is demonstrated. Numerical simulation of radiographic images is shown to provide a basis for the correct choice of the parameters of digital radiography systems as applied to testing large objects.
