Amniotic Fluid Index (AFI) (continued)
5. Perform a standard distance measurement for the second,
third, and fourth quadrants (see step 2).
When all four quadrants have been measured, the system
calculates the AFI and displays it in the Results Window.
HINTS
• If you unfreeze the image after doing an AFI measurement,
the system does not delete the previous measurements.
Unfreeze and change scan planes as necessary.
• To specify that an unassigned distance measurement be
used for an AFI measurement:
• Select AFI.
• Press Measure.
• Move the Trackball to highlight the unassigned
distance measurement in the Results Window.
• Select the AFI measurement on the Touch Panel.
• If the fluid in a pocket is zero, set the second caliper on top
of the first one to give it a zero value.
