The following table lists the measurements for each trimester. The label shows on the 2D
Image Display, and in the menu to select the measurement. When selecting a
measurement, if you do not see the needed measurement, check the Trimester value. You
may need to set the trimester to access the needed measurement.
If you make all four AFI measurements, the Terason application shows the AFI total.
