ACOUSTIC-PULSER FEEDBACK AND POWER FACTOR CONTROL OF A HIFU DEVICE |
摘要 |
<p>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.</p> |
