    Abstract: A method and system for adjusting a HIFU device compensates for shifts in transducer impedance so that the acoustic output from a HIFU transducer remains at a desired level. In accordance with a first aspect, the disclosure includes dynamically adjusting the tuning of a tuning network that causes the transducer/system to maintain an optimal power transfer to the acoustic output. In accordance with a second aspect, the disclosure monitors the acoustic output of the HIFU device and adjusts the electrical signal provided to the HIFU transducer to maintain a desired acoustic output.

    Abstract translation: 用于调整HIFU装置的方法和系统补偿换能器阻抗的偏移,使得来自HIFU换能器的声输出保持在期望的水平。 根据第一方面,本公开包括动态地调整调谐网络的调谐,使调谐器/系统保持对声输出的最佳功率传递。 根据第二方面,本公开监测HIFU设备的声输出并调整提供给HIFU换能器的电信号以保持期望的声输出。
