| 体外冲击波碎石是治疗人体结石症的有效方法之一,对冲击波声场的清晰认知,对于保障临床治疗的安全性和有效性具有重要意义。该研究通过制备新型针式水听器,搭建冲击波测量装置,对冲击波声场焦点平面进行检测,并对接收到的信号进行计算分析。实验表明：制备的针式水听器有着良好的性能；通过声场检测可以得到冲击波实际焦点位置,焦域大小及能流密度分布等各项参数；通过空化信号分析可得到其在该平面的统计分布特性。在实际应用中,为检测冲击波声场提供一种新的方法,同时清楚了解冲击波仪的各项声学参数分布特征并对其进行调整,可达到最佳治疗效果。 |

| Extracorporeal shock wave lithotripsy is one of the effective methods for the treatment of human lithiasis. Clear cognition of shock wave sound field is of great significance for the safety and effectiveness of clinical treatment. By preparing a new type of needle hydrophone and building a shock wave measuring device, the focus plane of the shock wave sound field is detected, and the received signal is calculated and analyzed. The experiments show that the prepared needle hydrophone has good performance; The actual focus position, focal area size and energy flux density distribution of the shock wave can be obtained by detecting the sound field. The statistical distribution characteristics of the cavitation signal in this plane can be obtained by analyzing the cavitation signal. In practical application, it provides a new method for detecting the sound field of shock wave, and at the same time clearly understand the distribution characteristics of acoustic parameters of shockwave meter and adjust them, so as to achieve the best therapeutic effect. |
