✦ Synopsis

Three different mathematical models were fitted to ultrasonic measurements of the biparietal diameter, head circumference, and abdomen circumference obtained from 1,426 healthy fetuses. The linear cubic function gives coefficients comparable with most previous studies, but it does not thoroughly explain fetal growth throughout pregnancy. Both the exponential-power function and the logistic-logarithmic function fit the raw data well and theoretically reflect the biological phenomena of human fetal growth. The characteristics of each model are discussed.

With the increasing use of ionizing radiations in diagnosis and therapy, one may predict that more and more human embryos and fetuses will be exposed to x-radiation. It is important, therefore, that data be accumulated relative to the radiosensitivities of specific organ primordia. It is apparent th
