The application of beam hardening correction for industrial X-ray computed tomography
The application of beam hardening correction for industrial X-ray computed tomography
X-ray computed tomography (CT) is a non-destructive, radiographic scanning technique that enables the visualisation of both the internal geometry and the composition of a workpiece; X-ray CT is therefore well suited for non-destructive inspection tasks. Several physical processes reduce the quality of CT images, and therefore influence both qualitative and quantitative analyses made from CT data-sets; one such physical process is beam hardening. In this work a simulation-based method is presented for correcting beam hardening, this method is applied to industrial X-ray CT measurement tasks and demonstrated to improve CT image quality.

Abstract
X-ray computed tomography (CT) is a non-destructive, radiographic scanning technique that enables the visualisation of both the internal geometry and the composition of a workpiece; X-ray CT is therefore well suited for non-destructive inspection tasks. Several physical processes reduce the quality of CT images, and therefore influence both qualitative and quantitative analyses made from CT data-sets; one such physical process is beam hardening. In this work a simulation-based method is presented for correcting beam hardening, this method is applied to industrial X-ray CT measurement tasks and demonstrated to improve CT image quality.
