中文摘要:
      超声“针灸”是利用二维相控阵实现声能在皮下不同深度的聚焦,刺激特定穴位,从而模拟传统针灸手法的治疗技术。对设计的超声针灸相控阵在不同聚焦深度下的垂直聚焦声场和偏转声场进行仿真,并对焦域进行统计分析,明确了所设计的相控阵探头延时聚焦声场可以满足超声“针灸”的“针形”声场要求。基于声场仿真,还对超声“针灸”声场控制模式进行了仿真研究,研究结果表明:控制超声相控阵聚焦声场聚焦位置的上下移动以及偏转聚焦,可以模拟传统针灸的提、插以及进针角度的变化,为超声“针灸”进一步模拟传统针灸手法提供了理论依据。
英文摘要:
      Ultrasound "acupuncture" uses two-dimensional phased arrays to focus acoustic energy at different depths under the skin and stimulate specific points to mimic the traditional acupuncture techniques. In this article, the focused sound field and deflected sound field of the designed ultrasonic acupuncture phased array at different focusing depths are simulated, and the statistical analysis of focusing areas is made. It is clear that the delayed focusing sound field of the designed phased array probe can meet the requirement of "needle shape" for ultrasonic "acupuncture". Based on sound field simulation, a simulation study of the sound field control mode of ultrasonic “acupuncture” is carried out. The results show that by controlling the up and down movement of focusing position and the deflection of focusing sound field, the change of lifting, insertion and entering angle in traditional acupuncture techniques can be mimicked, which provides a theoretical basis for the ultrasound “acupuncture” to further mimic the traditional acupuncture techniques.
