You can define the fetus growth by comparing the measured parameter value with the fetus
growth curve.
Operation procedure:
1. Measure one or more fetus growth parameter (GS, CRL, BPD, FL, AC, HC, APAD, TAD,
CER, FTA, HUM, OFD, or THD).
2. Enter LMP or BBT.

displayed. Then select Growth Curve and press Set, and the Fetus Growth Analysis dialog
box will be displayed in the middle of the screen.
4. The default tab is GS and the corresponding formula of the current growth curve. Move the
cursor to another formula in the pull-down menu, and press Set to display the normal growth
curve based on the selected formula, which can define how the fetus grows.
5. Move the cursor to another tab in the pull-down menu, and press Set to display the growth
curve of another measurement item and the phase of the growth corresponding to the
measured data.
The signification of the growth curves is shown below and the x-coordinate shows the phase of
the growth corresponding to the entered LMP or BBT, and the y-coordinate shows the measured
data.
Move the cursor to Close, and press Set to exit.
