AFI (Amniotic Fluid Index)
Measure the amniotic fluid index. Measurements are performed by dividing the pregnant woman’s
abdomen into four parts. The distance between the fetus and the farthest point of each area is
measured. To obtain a specific image from each quadrant plane, press the Freeze button to go
to the diagnosis mode. After obtaining the image, press the Freeze button again to return to the
measurement mode.
