In the HIFU treatment, whether it is extracorporeal to shock wave lithotripsy treatment equipment or Ultrasound HIFU piezo tumor treatment equipment,Ultrasonic generation and focusing devices are the core components. At present, there are three main sources of high-intensity focused ultrasound.A dif

Importance of medical ultrasond transducer shown in the whole ultrasonic imaging system,which can directly affect the image performance of the ultrasonic imaging system.As the development of piezoelectric materials,the improvement of production process and computer,the frequency of ultrasonic diagno

In this section, we designed a HIFU piezo ceramic treatment array with 125 channels and the array column structure was simulated by sound field, and the theoretical analysis of the array was continuous with the excitation signal at the frequency 2MHz. the result of single-point focusing under the st

People try to optimize the probe's array design parameters (such as array elements, array elements, etc.), optimizing the acoustic matching components of the probe, array element shape, size, fill rate, optimize the sound field meter for probe design and calculation method, optimizing. The signal mo

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

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

With the development of HIFU piezo ceramic technology, the HIFU technology has attracted great attention on the engineering and medical circles. Many units in China have carried out research and development and clinical application of HIFU equipment, and have achieved remarkable results. this paper

Heating tumor tissue has become one of the important methods for treating tumors. Ultrasound has become an important heating treatment because of its characteristics of easy to produce,it is focusable and invasive. In recent years, HIFU piezo for thermoplastic weight heating therapy technology has d

In recent years, the application of HIFU piezo transducer ultrasound in the field of tumor treatment has been widely concerned at home and abroad. It has been reported that nearly 10 domestic manufacturers have invested a lot of manpower and resources to develop in the clinical applications in the m
