Echolocation in bats was discovered by Lazzaro Spallanzani in , when he demonstrated that bats hunted and navigated by inaudible sound and not vision.

Francis Galton in invented the Galton whistle , an adjustable whistle which produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans. The first technological application of ultrasound was an attempt to detect submarines by Paul Langevin in The piezoelectric effect , discovered by Jacques and Pierre Curie in , was useful in transducers to generate and detect ultrasonic waves in air and water.

Measuring[ edit ] Diagram showing crown-rump length by gestational age. The blue line is the mean and the green area delimits the 3rd versus the 97th percentile. The measurement can actually vary slightly if the fetus is temporarily stretching straightening its body. The measurement needs to be in the natural state with an unstretched body which is actually C shaped. The measurement of CRL is useful in determining the gestational age menstrual age starting from the first day of the last menstrual period and thus the expected date of delivery EDD.

Different babies do grow at different rates and thus the gestational age is an approximation. Recent evidence has indicated that CRL growth and thus the approximation of gestational age may be influenced by maternal factors such as age, smoking , and folic acid intake. In that situation, other parameters can be used in addition to CRL. The length of the umbilical cord is approximately equal to the CRL throughout pregnancy.

Ultrasound scans and tests

Some abnormalities detected by ultrasound can be addressed by medical treatment in utero or by perinatal care, though indications of other abnormalities can lead to a decision regarding abortion.

Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.

Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results.

This means that combined first trimester screening will not give us a definitive answer. Chorionic villus sampling and amniocentesis are invasive tests, involving putting needles into the placenta or amniotic sac, and they are associated with an increased risk of miscarriage.

Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
