Automatic Calculation
Some items in the measurement menu are automatically calculated based on measurements of
other items.
NOTE: For reference, the Osaka University and Tokyo University methods are mainly used in Asia,
the Merz method in Europe, and the Shepard and Hadlock methods on the American continent.
AFI(Amniotic Fluid Index)
Measure the amniotic uid 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 specic 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.
