Referenceless Beam Hardening Correction in 3D Computed Tomography Images of Multi-Material Objects

Abstract

We propose a new method to reduce the effects of non-linearities such as beam hardening in Computed Tomography (CT) images. Due to the polychromatic characteristics of X-ray sources the ratio of attenuated and incoming intensity is not exactly exponential with the material thickness. Within CT images this leads to artifacts like cupping, streaks and… (More)
