Gravida and Para: These fields are identical to the US
report page as described on page 176.
Pregnancy Origin: The pregnancy origin field is similar

EFBW: The Estimated Fetal Body Weight is computed
using two distance calculations (BPD & FL) and one area
calculation (FTA).
Estimated Fetal Body Weight is automatically computed if
the above measurements have been made. Calculations
are made from the last measurement entered or averaged
using the formula:
EFBW[g] = 1.25647 x BPD[cm]
3
+ 3.50655 x FTA[cm
2
]
x FL[cm] + 6.3
GA (EFBW): The Gestational Age by Estimated Fetal
Body Weight is automatically computed if measurements
for EFBW are already made (BPD, FL and FTA). Please
refer to the EFBW (Osaka) table on page 342 for details.
EFBW (IU): If the standard deviation value for EFBW is
greater than 1.5, the EFBW (IU) is computed using the
formula: ;
EFBW(IUGR)[g] = 1.229 x BPD[cm]
3
+ 3.063 x FTA[cm
2
]
x FL[cm] – 24.6
GA (EFBW IU): Based on the calculations made for
EFBW(IU), the GA by EFBW (IU) is automatically
computed. Please refer to the EFBW (Osaka) table on
page 342 for details.
