A method analysing the local variations of a series of CT measurements to determine the single point noise is presented. Using a realistic simulation model of the CT system, the mean local offset and the single point uncertainty can additionally be estimated. The method is tested on a measurement series of a micropart. It is shown that the method is capable of identifying areas of increased uncertainty caused by artefacts and of quantifying the value of the single point uncertainty. Additionally, the method is validated using an existing method that is capable of assessing the local quality of a CT measurement.
