ABSTRACT
A pocket computer program is currently being used to perform complicated obstetric ultrasound calculations at the Medical Center Hospital of Vermont. The program calculates decimal weeks between dates, gestational age from biparietal diameter, crown-rump length or femur length, total intrauterine volume, head-abdominal circumference ratios, projected gestational age from previous measurements, and estimated fetal weight. Calculations can be printed for a permanent record. The pocket computer program provides a convenient, accurate, and affordable method of obstetric ultrasound analysis.
