Figure 8.

Reconstructions of a cadaveric knee obtained on the CBCT test-bench emulating the proposed extremities scanner and on a conventional CT system. CBCT images are shown for protocols corresponding to high-contrast bone visualization (0.1 mAs per projection and 2 × 2 detector binning) and soft-tissue visualization (0.25 mAs per projection and 2 × 2 detector binning). Axial, coronal, and sagittal slices through the reconstructions are presented (top to bottom row); in each case several slices perpendicular to the display direction were averaged to reduce noise. Voxel dimensions are listed beneath each image, with x, y, and z directions indicated by the axes at left.
