我们讨论了在超声（US）组织间加热中使用集成传感器进行温度测定的可行性。传感器是一个直径为230-/spl mu/m的微型热敏电阻，在US波导施用器的1.22 mm直径天线的尖端处用环氧树脂固定。将传感器结合到施用器中导致声输出下降约10%。虽然与天线周围的微电阻相比，集成传感器读取的温度要高得多，但加热曲线的形状非常相似。测量结果表明，体积温度可以从集成传感器的读数中推断出来，使用短暂的1.5分钟中断输送的US功率。
We discuss the feasibility of temperature determination with an integrated sensor in ultrasound (US) interstitial heating. The sensor, a 230-/spl mu/m diameter microthermistor, was epoxied at the tip of the 1.22-mm diameter antenna of the US waveguide applicator. Incorporation of the sensor into the applicator caused about 10% drop in the acoustic output. While the temperatures read with the integrated sensor were much higher compared to microthermistors around the antenna, the shape of the heating curves was very similar. Measurements show that the volume temperature can be inferred from the readings of the integrated sensor using short, 1.5-min interruptions in delivered US power.
