Francis Galton in 1893 invented the Galton whistle, an adjustable whistle that 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.
Many ask, who invented the ultrasound? Italian biologist, Lazzaro Spallanzani is most often credited person for discovering ultrasonography. Lazzaro Spallanzani (1729-1799) was a physiologist, professor and priest who carried out numerous experiments that led to great insights in human and animal biology.
Ultrasound was first used for clinical purposes in 1956 in Glasgow. Obstetrician Ian Donald and engineer Tom Brown developed the first prototype systems based on an instrument used to detect...
Ian Donald introduced the ultrasound in diagnostic and medicine in 1956, when he used the one-dimensional A-mode (amplitude mode) to measure the parietal diameter of the fetal head. Two years later, Donald and Brown presented the ultrasound image of a female genital tumor.
Diagnostic ultrasonography has evolved to become an indispensable imaging tool that permits non-invasive evaluation of the whole body. In this narrative review, we present a historical timeline of the invention, development, and evolution of diagnostic medical ultrasound.
Tom Fitzgerald, formerly a general practitioner, began using ultrasound in 1982 at the Victoria Hospital in Glasgow before applying to train in radiology, a growing specialty at the time.
1876 – Francis Galton, an English polymath, invents the Galton Whistle which produces a high frequency sound (ultrasound) inaudible to human ears. 1877 – John William Strutt, an English physicist, first describes sound waves as mathematical equations in his textbook The Theory of Sound.
The use of ultrasound in medicine began during and shortly after the 2nd World War in various centres around the world. The work of Dr.Karl Theodore Dussik in Austria in 1942 on transmission ultrasound investigation of the brain provides the first published work on medical ultrasonics.
Over the past 40 years, ultrasound has become an important diagnostic modality. Its potential as a leader in medical diagnostic imaging was recognized in the 1930s and 1940s, when Theodore Dussik and his brother Friederich attempted to use ultrasound to diagnose brain tumors.
The history of sonography in Obstetrics and Gynaecology dates from the classic 1958 Lancet paper of Ian Donald and his team from Glasgow. Fifty years on it is impossible to conceive of practising Obstetrics and Gynaecology without one of the many forms of ultrasound available today.
