The application of ultrasonic sensing technology in different aspects of production practice, and medical application is one of the most important applications, the following is illustrated by the medical example of ultrasonic sensing technology. The application of ultrasound in medicine is mainly to diagnose diseases, which has become an indispensable diagnostic method in clinical medicine.
The advantages of ultrasonic diagnosis are: No pain, no damage, simple method, clear image and high accuracy of diagnosis. Therefore, it is easy to popularize and is welcomed by medical workers and patients. Ultrasonic diagnosis can be based on different medical principles, so let's take a look at some of the representative type a methods. This method is the use of ultrasonic reflection.
When the ultrasonic waves in the human body to meet the two-layer acoustic impedance of the different media interface is that the interface produces reflection echoes. Each time a reflector is encountered, the Echo is displayed on the screen of the oscilloscope, and the impedance difference of the two interface determines the amplitude of the echo.
In industry, the typical application of ultrasonic is the nondestructive testing of metal and ultrasonic thickness measurement of two kinds. In the past, many technologies have been hampered by the inability to detect internal bodies of objects, and the advent of ultrasonic sensing technology has changed that. Of course, more ultrasonic sensors are fixed on different devices, "silently" to detect the signals people need. In the future application, ultrasound will be combined with information technology, new materials technology, will appear more intelligent, highly sensitive ultrasonic sensors.
