The use of ultrasound HIFU piezo ceramic for diagnosis and treatment has become one of the most important branches of medical bioengineering.More and more people are paying attention. As early as the 1930s, there were reports of ultrasound for treatment after forty years.Generations have proposed the possibility of ultrasound for diagnosis. However, due to the lack of organic connection between physical technology and medical knowledge at that time, and the limitations of engineering technology development and practical experience at that time, the development in the 1940s and 1950s was slow. There have been repeated treatments in the therapeutic applications.


Since the 1960s, until recently, due to the experimental study of the interaction between ultrasound and biological systems, the production of low-intensity ultrasound equipment has been available and accumulated a lot of clinical data and experiences, the application of ultrasonic piezoelectric transducer in the medical applications is extremely extensive and It is fast and increasingly shows its importance. Especially in the diagnosis, ultrasound with X-rays and radioisotopes become important clinical tools. Thousands of hospitals and medical centers use ultrasound as a routine clinical tool every day throughout the world. It can be used in different parts of the body, such as the brain, heart, liver, kidneys, and organs.


In the treatment, we have successfully applied low-intensity ultrasound to some parts of the human body for physiotherapy and massage.Osteopathic pain and various neuralgia, and the treatment of traumatic injuries of athletes is particularly successful.


Recently, in China, piezoelectric disc transducer is applied to the head to treat hemiplegia caused by cerebrovascular disease, and ultrasound treatment is used.The treatment of coronary heart disease has achieved remarkable results. The possibility of using higher-intensity ultrasound to quantitatively and repeatedly kill biological tissues (such as central nervous system tissue and other tissues) is also being studied abroad as a surgical procedure. According to foreign medical research groups,ultrasound fever is particularly effective in the treatment of head and neck squamous cell carcinoma. Ultrasound heat reduces the range of head and neck tumors by approximately 70% changes surface of 50% of the tumor.


The 3MHz frequency ultrasound can pass directly through the 4 cm transducer placed in the center of the tumor, and then help to place the tumor,A thermocouple needle inside to record the increase in temperature as the tissue is heated. With the ultrasound heat treatment, the side effects of the patient's surface burn are also small. If the piezoelectric plate transducer acoustic device is further improved and the release energy is delivered more accurately, the side effects will be eliminated. Larger or deeper tumors can be treated with multiple transducer systems.


By the diagnosis, acoustic piezoelectric sensor has two major advantages: one is non-invasive, and the other is to distinguish between different acoustic impedances.The ability to interface between soft tissues. X-ray diagnosis, it only reflects the difference in the tissue density, such as non-bone organs, contrast fluid must be injected to make it visible,which scans nuclear physics medicine technology that is the measurement of the selective appearance of radioisotopes in the special organs to determine organ structure and pathology . These agents and isotopes are invasive and have some effect on the human body, sometimes with the additional surgery.


However, there is ultrasound diagnosis with low intensity sound intensity, in addition to guarantee to send sound waves into the body (innocuous at this intensity) without any surgery and auxiliary agents (sometimes only drinking water or swallowing organic film pellets filled with water, it is harmless to the human body) It is only necessary to apply a layer of oil on the skin of the ultrasonic piezoelectric vibration sensor and the human body to ensure that the sound waves are in contact. So it is non-invasive and non-invasive. Because of its ability to resolve the acoustic impedance interface, it can distinguish various lesions of soft tissue, such as displacement, deformation, lesions, foreign body proliferation and so on. Therefore, more clinical data can be obtained than other methods. Ultrasound diagnosis has now been widely used in the cardiology, obstetrics, gynecology, abdominal scans, midbrain detection, eye scans, blood flow determination.
