The metrological structural resolution for dimensional x-ray CT: analysis of the comparability between the CEB and the PBS method

Autor: René Laquai, Jens Illemann, Markus Bartscher, Ulrich Neuschaefer-Rube

Publikováno v: Measurement Science and Technology. 34:084002

The metrological structural resolution (MSR) describes the size of the smallest surface feature that can be measured dimensionally with a given accuracy. Several methods to determine the MSR for dimensional x-ray CT (dXCT) have been proposed in the p

Case Study of Empirical Beam Hardening Correction Methods for Dimensional X-ray Computed Tomography Using a Dedicated Multi-material Reference Standard

Autor: Christian Gusenbauer, Markus Bartscher, Fabrício Borges de Oliveira, Johann Kastner, Michael Reiter

Publikováno v: Journal of Nondestructive Evaluation. 38

This paper presents a case study of two selected beam hardening correction methods and their effects on dimensional measurements of multi-material objects. The methods under test are empirical cupping correction (ECC) and empirical dual energy calibr
