Overlapped Axial Recon Mode; Secondary Recon Slice Thickness - GE Revolution CT User Manual

select which viewport a reconstruction will display in. Refer to the
details. Follow the primary reconstruction workflow to set the reconstruction parameters.
A reformat step can also be added on secondary reconstructions, as well as output and transfer
options. Refer to the

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.
