In the field of cancer treatment, high-intensity focused ultrasound HIFU tumor treatment technology is the fourth new tumor treatment technology after surgery, chemotherapy and radiotherapy. The common HIFU piezo ceramic in the clinic is to use the ultrasonic medium to radiate energy to the tumor si

For a multivariate linear array transducer with Zn+1 array elements, if all the array elements emit sound waves at the same time,Let the sound pressure value of the array element at point F be p: then the total sound pressure of point F value is: pSince the distances of the respective line elements

Mechanical sector scanning is performed by a motor driven by a single or multiple piston transducers around a fixed axis or a scanning system formed by rotation. Usually the transducer is placed in a container filled with liquid, the entire system is close to keep contact with the surface of the hum

Ultrasound focusing piezo ceramic is not only important ultrasound surgery, but also ultrasound diagnostics. people always want to see smaller, more subtle organizational structures, such as the internal organization of the internal organs of the human body, eyes and skin, etc., not only to increase

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 th

In recent several decades,ultrasonic phased arrays had been applied to many medical specialties and nondestructive evaluation(NDE).An ultrasonic phased array consists of multiple Hifu piezo transducer impedance which are usually cut or etched from a single piezoelectric plate of lead zirconate tina

HIFU uses secondary HIFU piezo ceramic technology to transmit ultrasonic waves from multiple probes to outside the patient's body, and focuses of the lesion to form a high-intensity focal spot similar to the size of rice. Producing high temperature to burn cancer cells. For the purpose of treatment,

Almost all methods must measure the acoustic characteristics of various tissues and their temperature characteristics, and these parameters usually vary from tissue to tissue, which brings difficulties in ultrasonic non-destructive temperature measurement technology. This is an urgent need to solve

With the continuous development of computer technology, computers have become an indispensable control for ultrasonic high focus piezoelectric treatment systems. In the actual treatment process, the target should be tracked and monitored in the real time through the computer! The target is compared

The planetary deceleration technology can make the precision of scanning reach 0.01mm, and then use the medium and high grade B-ultrasound and Hifu piezoelectric crystal treatment system to form IC parts, it guides the positioning and target tissue, and implement the monitoring effect. For the first

When HIFU piezo ceramics technology is used for tumor treatment, especially for abdominal tumor treatment,it is breathing that will cause a large movement of the abdominal organs. The displacement can even reach a dozen millimeters. Anesthesia can stabilize the patient's breathing, but organ displac

With the development of science and technology, the non-destructive testing technology of temperature field has made great progress, and some non-destructive side temperature methods of HIFU piezo ceramic have been proposed.Such as electrical impedance tomography, magnetic resonance (M IR) ultrasoun

The temperature field of HIFU piezo ultrasound for tumor treatment can be generally divided into two types: thermotherapy and ablation therapy. The former is to heat the tumor about 43°C to 45°C,which keep it for several tens of minutes to inhibit tumor growth. The latter uses HIFU to make the targe

The measurement of 250Khz hifu piezo is mainly the focus sound field characteristic - it is the focusing parameter. Because ultrasonic waves are prone to cavitation and nonlinear effects under water and human tissues, it is unpredictable factors, especially the focused sound field characteristics of
