Sažetak
Period of use of computed tomography (CT) for purposes of dimensional measurements started about 10 years ago and it is still on its beginning. It is a method that has a lot of advantages and can be used for many purposes, e.g. for material inspection, dimensional inspection, in quality control etc. at the same time and with only one scanning of the product. In order to ensure metrological traceability of the method, measurement uncertainty needs to be assessed. Since the CT method has a lot of infl uencing factors, assessment of measurement uncertainty is a very complicated process. In order to evaluate measurement uncertainty of results according to GUM (Guide to the expression of the uncertainty in measurement), infl uences of all factors need to be identifi ed and each individual in- fl uence on results needs to be specifi ed. Since the CT dimensional measurement is achieved through several stages, infl uence parameters can be divided according to that criterion into: parameters infl uencing scanning process, parameters infl uencing reconstruction process and parameters infl uencing measurement process. In this research combination of diff erent parameters on measurement results will be investigated and analyzed.
