Beam hardening correction for X-ray computed tomography of heterogeneous natural materials
We introduce a new method for CT beam-hardening correction. We demonstrate how our correction can be optimized by an expert user. We show examples of CT beam-hardening artifacts in various geological specimens. We show how our correction can improve delineation of object boundaries. We discuss how beam-hardening and other effects combine to create complex artifacts.
