Multi-Material Blind Beam Hardening Correction Based on Non-Linearity Adjustment of Projections
Ammar Alsaffar, Kaicong Sun, Sven Simon
Beam hardening (BH) is one of the major artifacts that severely reduces the quality of Computed Tomography (CT) imaging. In a polychromatic X-ray beam, since low-energy photons are…
Computational Scatter Correction for High-Resolution Flat-Panel CT Based on a Fast Monte Carlo Photon Transport Model
Ammar Alsaffar, Steffen Kieß, Kaicong Sun +1
In computed tomography (CT) reconstruction, scattering causes server quality degradation of the reconstructed CT images by introducing streaks and cupping artifacts which reduce th…
FL-MISR: Fast Large-Scale Multi-Image Super-Resolution for Computed Tomography Based on Multi-GPU Acceleration
Kaicong Sun, Trung-Hieu Tran, Jajnabalkya Guhathakurta +1
Multi-image super-resolution (MISR) usually outperforms single-image super-resolution (SISR) under a proper inter-image alignment by explicitly exploiting the inter-image correlati…
