Figure 5

(a) The axial and cross-sectional images show the soft tissue of syCBCT with less noise, whereas more heterogeneity is observed in CBCT (dotted box). The scattering artifact (arrow) in the CBCT image is not evident in the syCBCT image. The margin of tooth structure is blurred in syCBCT. (b) Three-dimensional reconstruction of CBCT and syCBCT using the maximum intensity projection method. CBCT, cone-beam computed tomography; syCBCT, synthetic CBCT.
