Figure 1 Different kinds of artifacts caused by the coaxial needle in the originally reconstructed cone-beam computed tomography images. A: Radial artifacts; B: Streak artifacts; C: Thickening artifacts; D: Dark streak; E-H: After streak metal artifact reduction technique reconstruction, all kinds of artifacts can be significantly suppressed. SMART: Streak metal artifact reduction technique.

Figure 2 In the original cone-beam computed tomography images, the metal artifacts interfere with the visualization of the vessels around the target lesions. A and B: Original cone-beam computed tomography images; C and D: After streak metal artifact reduction technique reconstruction, the vessels can be clearly visualized as indicated by the arrows. SMART: Streak metal artifact reduction technique.
