Evaluation of ultrasonic obstetrical parameters by hand-held calculator.
One consequence of the development of the use of ultrasound in obstetrics is the multiplication of parameters studied by the ultrasonographer. This has prompted the development of expensive computerized systems to assist the person doing the examination in evaluating his results. A program designed to be used with a relatively inexpensive, hand-held calculator is described. It gives the gestational age corresponding to the most commonly measured dimensions, the estimation of fetal weight of the examined fetus, and numerous other parameters used in clinical interpretation of ultrasound examinations.
