[An original method of echographic fetal measurements]

The authors have tried to look at the graphs of ultrasound growth in their population in order to establish a base pattern. The infants were divided into groups according to their frame and a study of each diameter was made for each group. The authors show that all babies that start off from the same point arrive at their final stature which is different from all others because of their own rates of growth. The curve which is suggested fits in with this spread. The way it is built up has been explained as well as the follow-up studies that show that it is valid. The discussion points out that the rates of growth can be measured; and the value of the diameter of the thorax.
