SPHERICAL ULTRASONIC HIFU TRANSDUCER WITH MODULAR CAVITATION SENSE ELEMENT

摘要

An ultrasonic HIFU transducer has a threaded opening into which a modular cavitation sensor is removably located. The modular cavitation sensor includes a modular housing containing a piezoelectric transducer for sensing acoustic signals indicative of cavitation. The modular cavitation sensor has electrodes which engage spring contacts in the threaded opening when the modular housing is screwed into the threaded opening. A damaged sensor can be unscrewed and replaced simply without connectors or soldering.
