Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.
The blood vessels commonly interrogated include the umbilical artery , the aorta , the middle cerebral arteries , the uterine arcuate arteries , and the inferior vena cava. The use of color flow mapping can clearly depict the flow of blood in fetal blood vessels in a realtime scan, the direction of the flow being represented by different colors. Color doppler is particularly indispensible in the diagnosis of fetal cardiac and blood vessel defects , and in the assessment of the hemodynamic responses to fetal hypoxia and anemia.
A more recent development is the Power Doppler Doppler angiography.

History Galton whistle, one of the first devices to produce ultrasound Acoustics , the science of sound , starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. 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.
