Description

Scattering of the x-ray photons by the test object constitutes one of the most important physical mechanisms having a significant impact on radiographie image. Depending upon equipment setup, inspection parameters and material of the test object, contribution of scattering to the photon intensity may vary from a few percent of the overall beam incident upon the detector to more than half of the overall beam intensity. Therefore, a quantitative understanding of mechanics of scattering is an important issue in implementation of existing radiographie procedures and development of new ones. Development of computational models simulating scattering in radiographie studies provides the means for quantitative study of scattering phenomena. In addition to parametric studies enabled by such computational models, existence of such codes can also be utilized by the radiography simulators which have been gaining significant visibility in the last decade.
