chapter for more details.
6.4.1 Overlapped Axial Recon mode
The system supports the reconstruction of overlapped data from Axial scan type 40, 80, 120,
140, 160 mm detector coverage. The reconstruction of overlapped Axial data can improve
reformatted data. The interval cannot be adjusted.
Images reconstructed with the 0.625 Z recon mode will be annotated with a Z in the upper-left
area of the images.
