key problem of HIFU technology development

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 discusses some key issues in the development of HIFU technology: (1) Focused ultrasound transducer:High intensity focused piezo transducer is the core of HIFU technology engineering, it is the most critical technology, The choice of the design of the energy device is very important; (2)  It is the key parameters and the control of the focused ultrasound field, it is the ultrasonic working frequency, the focal length, the focal spot, the sound intensity, the side lobes and other key parameters,high focused ultrasound field has the most HIFU technology engineering. The key point is that measures must be taken to control the quality of the focused sound field to ensure the safety and effectiveness of IH UF treatment. The focus sound field is also one of the basic work of Hifu piezo transducer engineering; (3) HIFU temperature field measurement: HIFU technology organism has effects and tissue type, it is ultrasound frequency, ultrasound intensity, number of irradiation, etc. Which are all intrinsically linked to control temperature changes and heat in the HIFU treatment area. The influence of the source on the surrounding tissues is the prerequisite for selecting a reasonable treatment plan to achieve non-invasive treatment;(4) When breathing is synchronized with HIFU ultrasound piezo ceramic, when the abdominal tumor is treated, the breathing will cause a large displacement of the organ, and the movement of the organ will cause the target area to deviate, thereby affecting the precise treatment of the IH treatment system, and even causing serious (5) Three-dimensional reconstruction, computer-assisted surgical intervention and ultrasound ablation identification technology: How to evaluate the efficacy of HIFU, in the actual treatment process, should track and monitor the target location in real time, provided computer-assisted intervention and ablation identification technology to ensure safe and effective treatment; (6) Adaptability of treatment system: The design of HIFU equipment should be “people-oriented”, and high intensity focused ultrasound should be able to adapt to the needs of various parts of cancer treatment; (7) Study of ultrasound, One of the foundations of HIFU technology for treating tumors is that ultrasound can kill tumor cells, and some tumor cells are more sensitive to ultrasound than normal cells. Studies have shown that the mechanism of ultrasound acting on biological tissues is a comprehensive and complex process. The study of ultrasonic broth is the main reason why HIFU technology can be truly promoted.
