company news about History of Ultrasonic

From the end of the 19th century to the beginning of the 20th century, after the piezoelectric effect and the inverse piezoelectric effect were discovered in physics, people solved the method of using electronics to generate ultrasonic waves. Since then, the historical chapter of the development and promotion of ultrasonic technology has been quickly opened.

In 1922, the first invention patent for ultrasound therapy appeared in Germany;

In 1939, a literature report on the clinical effects of ultrasound therapy was published.

Ultrasonic therapy emerged in Europe and the United States in the late 1940s. It was not until the first international medical ultrasound conference held in 1949 that there was an exchange of papers on ultrasound therapy, which laid the foundation for the development of ultrasound therapy.

In 1956, many papers were published at the Second International Conference on Ultrasound Medicine, and ultrasound therapy entered the stage of practical maturity.
