Metal Artifacts Correction Method Research about Liquid Metal Angiography
Abstract：Computed Tomography (CT) can be used in the visualization on theanatomical vessel networks.Liquid metalangiographycanenhancethevessel networks. Because the liquidmetalcontrast agent hashighlinear attenuation coefficient, the reconstructed images usually have radial metal artifacts, which will cause the inaccurateedges of thevessels.To solve this problem, a new correction method based on bone beam-hardening correction is developed.The experiment results show that it can reduce the metal artifacts inisolatedpigkidney liquidmetalangiographyimageand improve the image quality.
