4 On the control box, press the Start key.
Radiation starts. The topogram is displayed in the upper-left
segment (topo segment) of the Examination task card. The
topogram is used to plan the ranges for scanning and
reconstructing tomograms.
Subsequent examination ranges are graphically marked on the
topogram:
• Magenta: the active (selected) range
• White: all other (unselected) ranges
• Yellow: an invalid range
The topogram is displayed in real-time to indicate the scan progress.
As soon as the desired portion of the topogram appears, you can
suspend the topo scan, thereby reducing the patient’s exposure to
radiation.
