What are the application fields of functional medicine

Ultrasound also has a good application in medicine. The application of ultrasound in medicine is mainly to diagnose diseases, which has become an indispensable diagnostic means in clinical medicine. The working principle of medical ultrasonic examination is similar to sonar, that is, when ultrasonic waves are emitted into the human body, they will be reflected and refracted when they meet the interface in the body, and may be absorbed and attenuated in the human tissue. Due to the different shapes and structures of various tissues in the human body, the degree of reflection, refraction and absorption of ultrasonic waves is also different. Doctors distinguish it by the characteristics of the wave pattern, curve or image reflected by the instrument. In addition, combined with anatomical knowledge, normality and case changes, it can be diagnosed whether the examined organ is sick or not. The advantages of ultrasonic diagnosis are: no pain, no damage, simple method, clear imaging and high diagnostic accuracy.
