- The temperature field of HIFU piezo ultrasoundThe 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 targeHIFU Piezo information July 17, 2018
- key parameters and control of high focused piezo(二)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 ofHIFU Piezo information July 15, 2018
- key parameters and control of high focused piezo(一)The measurement of ultrasonic working frequency, focal length, focal spot, sound intensity, side lobes and other key parameters and the quality of the focused sound field are the key to HIFU piezo ceramictechnology engineering, which have an inseparable relationship with the performance, efficacy anHIFU Piezo information July 15, 2018
- Focusing method of HIFU piezo transducerThe study of high-intensity focused ultrasound technology has been make effect since the 1940s, but limited by engineering technology at the time, the technology has not been rapidly developed. With the rapid development of related technologies such as computers, technology has attracted great attenHIFU Piezo information July 14, 2018
- key problem of HIFU technology developmentWith 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 paperHIFU Piezo information July 13, 2018
- researching on multi-frequency HIFU piezo transducerIn order to realize the HIFU ultrasound piezo, the traditional methods mostly use a single frequency ultrasonic transducer, and the use of the same focusing system to achieve the focus of the two frequency ultrasound is rarely reported. In 1996, Japanese scholar S. Umemura et al. studied a techniqueHIFU Piezo information July 12, 2018
- Technical improvement of the HIFU transducer(1) About planar annular array transducer. A concentric small circular area is dug in the center of the circular piston source to form an annular planar sound source.The sound pressure generated by the annular planar sound source at any point in space can be regarded as the sound pressure generatedHIFU Piezo information July 12, 2018
- Research on Focused Ultrasonic Transducer in HIFU TechnologyHigh-intensity focused ultrasound (HIFU) technology is originated in the 1940s. It is a certain way to make the ultrasound accumulate on the lesion tissue after passing through the body surface. After the interaction between the cells and the ultrasound in the lesion tissue. Producing irreversible cHIFU Piezo information July 11, 2018
- Theoretical study of concave spherical ultrasonic and high focused ultrasound for hyperthermia(2)The maximum sound pressure and the rising temperature is produced by the two sound sources differ greatly, but the ratio of the maximum temperature rise to the maximum sound absorptivity is almost the same.High intensity focused piezoelectric ceramic is indicating that the efficiency of the absorptiHIFU Piezo information July 10, 2018
- Theoretical study of concave spherical ultrasonic and high focused ultrasound for hyperthermia(1)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 dHIFU Piezo information July 10, 2018
