Comparison of simulation-computed tomography (CT) and HyperSight cone beam (CB) CT on patients with dental filling. (A) The top figures were fan-beam Siemens simulation-CT with metal artifact reduction, and the bottom figures were HyperSight CBCT with iCBCT MAR reconstruction. (B) The top figures were fan-beam GE simulation-CT (without metal artifact reduction), and the bottom figures were HyperSight CBCT with iCBCT MAR reconstruction. For each set of images, the first 3 images were displayed at a window width of 800/-400 HU, and the fourth image at 225/-125 HU.
