Automatic Detection and Measurement of Fetal Biparietal Diameter and Femur Length—Feasibility on a Portable Ultrasound Device
An automatic method able to recognize a presented section through the biparietal plane of the fetal head and a section through the fetal femur in ultrasound images is developed. Once the correct anatomical section for measurement is identified by the machine, the placement of the measurement calipers is automatically determined by fitting an active contour model to the structure of interest. Th...

متن کاملUltrasound assessment of fetal biparietal diameter and femur length during normal pregnancy in Iranian women.
OBJECTIVES To determine the pattern of intrauterine growth and predicted biparietal diameter (BPD) and femur length (FL) at point in gestation of Iranian fetuses. METHODS In an extensive and long-standing prospective study in Tehran, Iran 15693 BPD and 15594 FL measurements were obtained from the fetuses of 1324 normal pregnant women.

متن کاملIntrauterine Fetal Growth Retardation: A Comparison of Human Placental Lactogen Urinary Oestriol and Biparietal Diameter Measurements
In a previous communication, Robinson et al. (1973) compared the value of five methods of fetal monitoring in respect of their ability to differentiate between normal and growth-retarded pregnancies in a small series of patients. These tests included sonar biparietal cephalometry, 24 h urinary oestriol assays and determination of serum oxytocinase, total alkaline phosphatase and heat-stable alk...
