A Brief History of Ultrasound Technology

Ultrasound has had many uses over the years that reach far beyond the beauty industry. The 18th century is generally agreed to be the time when people discovered the principles of ultrasound. Lazzaro Spallanzani discovered that bats used the echoes of high-frequency sounds to navigate in dark surroundings.

In the late 19th century, the Curie brothers observed that crystals produce electrical energy after they applied pressure to them. This led to the creation and reception of ultrasound waves. When the Titanic sank in 1912, this triggered the invention of hydrophones, which converted sound waves into electrical energy. This detected objects at the bottom of the sea. Around this time, researchers developed sonar technology using sound waves. The first sonar device emitted low-frequency sound waves and then registered any echoes of the sound waves caused by a nearby object.

Ultrasound History

In the 1930s, the application of ultrasound waves continued to increase and become more diverse. One use of ultrasound was its ability to detect flaws in metal. The principle of reflection was used to detect flaws such as cracks. Flaw in the metal reflected the sound waves back to the transmitter, and altered the travel time of the sound wave. This allowed people to isolate the position of defects in the material.

Ultrasound technology was introduced into the medical industry around the 1930s and 1940s. However, it is important to note that during the 1920s, researchers used sonography in a therapeutic context. Football players received treatment using ultrasonic waves to relieve pain from arthritis and other conditions. It wasn’t until 1942 that Karl Dussik used ultrasound as a diagnosis tool. Using the principle of sonography, transmitters fired ultrasound waves into the skull to diagnose brain tumours. By tracking the path of the waves from one side of the head to the other, Karl Dussik believed this could pinpoint the location of tumours.

There were multiple developments in ultrasound technology in the medical industry throughout the 20th century. This includes the use of ultrasound to find gallstones, and the introduction of echocardiograms, which gives doctors an indication of the structure of the heart. Furthermore, ultrasound gave doctors the ability to examine patterns of blood flow.

Medical professionals used ultrasound technology for baby scans in 1958. Of course, this was not as advanced as modern-day ultrasound scans. However, it could identify tumours and abnormalities of the foetus and gave rough measurements of the baby. In 1986, researchers developed 3D ultrasound, resulting in realistic and real-time images of the foetus in the womb. Through the 21st century, 4D ultrasound and video technology have been created, meaning that doctors can easily monitor the health of babies before they are born. Ultrasound technology is certainly a beneficial addition to the medical industry, and will probably help the majority of us in the future.

As ultrasound technology has developed, so has its use in cosmetic treatments. It effectively reduces fat in difficult to target areas by using vibrations to break up the fat cells. In addition to this, types of ultrasound such as HIFU (High-Intensity Focused Ultrasound) have aesthetic benefits such as tightening the skin. Furthermore, HIFU, in particular, penetrates through multiple layers of the skin to improve the strength of the muscle layer. In the case of our NextGen HIFU and FemiWand machine, HIFU tightens both the face and the vagina.

The use of ultrasound to conduct Vaginal Tightening shows just how far ultrasound technology has come. Initially, it examined large areas such as the sea floor, whereas now it can treat tiny and focused areas. There is no doubt that more functions of ultrasound will come to light in the future. Invest in ultrasound technology and reap the benefits of this advanced and versatile technology.
