Paper Summary:

A look at the history and uses of ultrasound technology. According to the paper, ultrasound is a medical technology that is used to diagnose various diseases and other disorders, as well as contribute to a healthy pregnancy, or diagnose fetal abnormalities.

From the Paper:

"Ultrasound technology's roots are in the development of SONAR technology in the mid-19th century. The concept of high-frequency sound waves, or "ultrasound," had been around since the late 18th century when an Italian scientist began exploring the natural navigational system used by bats. In 1876, Francis Galton developed the Galton whistle, which was capable of producing the high-frequency sounds, however, "The real breakthrough in the evolution of high frequency echo-sounding techniques came when the piezo-electric effect in certain crystals was discovered by Pierre Curie and his brother Jacques Curie in Paris, France in 1880" (Woo, 1). RADAR and radio technology developments during World War I also had a reasonable contribution to the early development of ultrasound."
