    • Abstract
  • Computed Tomography(CT) can be used in the visualization on the anatomical vessel networks. Liquid metal angiography can enhance the vessel networks. Because the liquid metal contrast agent has high linear attenuation coefficient, the reconstructed images usually have radial metal artifacts, which will cause the inaccurate edges of the vessels. 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 in isolated pig kidney liquid metal angiography image and improve the image quality.
