Features of ultrasound
- When ultrasonic waves are propagated, the directionality is strong, and the energy is easily concentrated.
- Ultrasonic waves can propagate in various media, and can spread far enough.
- The interaction between ultrasound and sound medium is moderate, and it is easy to carry information about the state of the sound medium (diagnosis or effect on the sound medium. (Treatment)
Ultrasound is a form of fluctuation, which can be used as a carrier or medium for detection and load information (such as B-ultrasound etc.); ultrasound is also a form of energy. When its intensity exceeds a certain value, it can pass through The interaction of the medium that transmits the ultrasonic waves affects and changes the state, nature and structure of the latter (used as a treatment).
