[PDF][PDF] Statistical image reconstruction with sample-based beam-hardening compensation for X-ray CT
Abstract—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 …

[PDF][PDF] Segmentation-free statistical method for polyenergetic X-ray computed tomography with a calibration step
The polyenergetic nature of the spectra in X-ray sources can cause artifacts and non-
quantitative values in the reconstructed image because of the beam-hardening effect. There …

[PDF][PDF] New method for correcting beam-hardening artifacts in CT images via deep learning
Beam-hardening is the increase of the mean energy of an X-ray beam as it traverses a
material. This effect produces two artifacts in the reconstructed image: cupping in …
