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…
