Multi-materials beam hardening artifacts correction for computed tomography (CT) based on X-ray spectrum estimation
Wei Zhao, Dengwang Li, Kai Niu +3
Due to the energy-dependent nature of the attenuation coefficient and the polychromaticity of the X-ray source, beam hardening effect occurs when X-ray photons penetrate through an…
Image Domain Dual Material Decomposition for Dual-Energy CT using Butterfly Network
Wenkun Zhang, Hanming Zhang, Linyuan Wang +5
Dual-energy CT (DECT) has been increasingly used in imaging applications because of its capability for material differentiation. However, material decomposition suffers from magnif…
Segmentation-Free X-ray Energy Spectrum Estimation for Computed Tomography Using Dual-Energy Material Decomposition
Wei Zhao, Lei Xing, Qiude Zhang +2
X-ray energy spectrum plays an essential role in computed tomography (CT) imaging and related tasks. Due to the high photon flux of clinical CT scanners, most of spectrum estimatio…
Segmentation-free x-ray energy spectrum estimation for computed tomography
Wei Zhao, Qiude Zhang, Tianye Niu
X-ray energy spectrum plays an essential role in imaging and related tasks. Due to the high photon flux of clinical CT scanners, most of the spectrum estimation methods are indirec…
