Abstract

U ovome radu je obrađivano područje računalne radiografije, koja je jedna od metoda nerazornih ispitivanja. Cilj samoga rada jest ustanoviti koje su prednosti i mane računalne radiografije u usporedbi s drugim relevantnim postupcima određivanja promatranih značajki. Nadalje bit će navedeni bitni parametri kvalitete slike (SR, SNR, CNR). Isti će također biti detaljnije opisani te izmjereni po aktualnim normama. Eksperimentalni dio rada sastoji se od snimanja predmeta postupkom računalne radiografije te provjere na koji način će se mijenjati parametri kvalitete slike s obzirom na mijenjanje ispitnih parametara i parametara skeniranja (tip slikovne ploče i veličina pixela (pixel size)).

Abstract (english)

This paper talks about computed radiography, which is one of the methods of non-destructive testing. The goal of this paper is to establish which are the advantages and drawbacks of computed radiography in comparison to other relevant methods of discovering flaws in the material. Furthermore the image quality parameters will be listed (SR, SNR, CNR). They will also be explained in more detail and measured in accordance to current norms. The experimental part of the paper consists of scanning an object and reviewing how the changes in test parameters and scan parameters (type of imaging plates and pixel size) affect image quality parameters.
