Abstract

U ovome je radu, kao jedna od metoda nerazornih ispitivanja, obrađena računalna radiografija. Za potrebe teoretske razrade rada, opisani su fizikalni mehanizmi djelovanja olovnih folija na senzore ionizirajućih zračenja. Kako bi se odredio utjecaj olovnih folija na kvalitetu digitalnog radiografskog zapisa, provedena su laboratorijska ispitivanja kod kojih su varirane debljine olovnih folija, vrste slikovnih ploča i energije zračenja. Dobiveni digitalni radiografski zapisi analizirani su softwareom StarrPlot. Interpretacijom rezultata donesen je zaključak o isplativosti korištenja olovnih folija kod računalne radiografije.

Abstract (english)

The thesis deals with computed radiography, one of the non- destructive testing methods. The physical mechanisms of the effect lead screens have on the ionizing radiation sensors have been described in the theoretical part of the paper. Experiments were carried out to determine the influence of lead screens on the quality of digital raiographic images. In those experiments, different lead screen thicknesses, image plates and radiation energies were varied. Obtadined digital radiographic images were anlized using the StarrPlot software. The results interpretation provided the conclusion regarding the use of lead screens in computed radiography.
