Fetal biometry and estimated fetal weight Western versus Indian standards at 39 and 40 weeks (Figure 2). By the study, we have developed a chart of fetal biometry and estimated fetal weight for gestational age 32-40 weeks in Indian population. Our study correlates well with the study of Rajan et al.,6-81993 both in fetal biometry and

fetal biometry can always be reconstructed from a 3D volume taken at any orientation, whether this is possible throughout gestation and whether such reconstructed images yield the same measurement as an optimally acquired 2D image of the same structure. In this study we acquired fetal 3D volumes throughout gestation (14–41weeks).
