We present a new method for correcting beam hardening artifacts in polychromatic X-ray CT
data. On most industrial CT systems, software beam-hardening correction employs some …

X-ray Computed Tomography scanning is an innovative procedure that allows representing
the internal structure of samples. Among its several purposes, X-ray CT is widely used for …

Beam hardening is a well-known effect in X-ray CT scanning that is caused by the
interaction of a broad polychromatic source spectrum with energy-dependent material …

We propose a post-reconstruction correction procedure for the beam-hardening artifact that
neither requires knowledge of the X-ray spectrum nor of the attenuation coefficients in multi …

The polychromatic X-ray spectrum and the energy-dependent attenuation coefficient of
materials cause beam hardening artifacts in CT reconstructed volumes. These artifacts …

The aim of this paper is to develop a fast and accurate beam hardening correction method
by modeling physical interactions between X-ray photons and materials for computed …

Beam hardening in x-ray computed tomography (CT) is inevitable because of the
polychromatic x-ray spectrum and energy-dependent attenuation coefficients of materials …

Purpose: Due to x‐ray beam polychromaticity and scattered radiation, attenuation
measurements tend to be underestimated. Cupping and beam hardening artifacts become …

The polychromatic spectrum of X-ray beams causes beam hardening artifacts in
reconstructed computed tomography (CT) models. This leads to unwanted grey value …

CT images are often affected by beam-hardening artifacts due to the polychromatic nature of
the X-ray spectra. These artifacts appear in the image as cupping in homogeneous areas …
