Workflow Information
To define the reference image (topogram) to the active
segment, click on the Set Reference Segment button.
This defines the orientation of the reference image
which will be added to the result images.
Once you have finished the adjustment, start calcula-
tion of the result images by clicking on the Recon but-
ton. You can start a recon job at any time, indepen-
dently of other ongoing jobs (asynchronous
reconstruction). After starting the recon job the layout
of the Examination task card changes back to the
standard layout. If "auto recon" is selected, all defined
recon jobs start automatically after scanning.
The progress of reconstruction is displayed by the
slider in the tomo segment.
