用S矩阵法优化设计功率换能器系统

Optimum Design of Power Ultrasonic Transducer system Using S-Matrix Method

本文从一个较新的角度,即 S 矩阵分析法,分析了功率超声换能器系统,并引入了最优化算法进行设计,避免了传统设计中近似建模的不精确性及硬件实现过程中人工调试的繁琐,实验结果与理论分析吻合。以此为依据设计的超声手术刀用于多种外科手术,性能良好。

The S-matrix analyzing method is employed in this paper for the analysis of a power ultrasonic transducer system. An optimal algorithm is introduced in the design of the system to avoid the inaccuracy caused by approximate modeling in traditional design and the complexity of manual adjustment and testing in the process of hardware design. The experimental result is in comply with the theoretical analysis. The designed ultrasonic surgical instrument based on this is of good performances and has been used in clinical practice.
