Beschreibung
Zusammenfassung:	An ultrasonic HIFU transducer (120) has a threaded opening into which a modular cavitation sensor (90) is removably located. The modular cavitation sensor includes a modular housing (92) containing a piezoelectric transducer for sensing acoustic signals indicative of cavitation. The modular cavitation sensor has electrodes (96,98) which engage spring contacts (112,114) 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. L'invention concerne un transducteur HIFU sphérique présentant une ouverture filetée dans laquelle est logé amovible un capteur de cavitation modulaire. Le capteur de cavitation modulaire comprend un boîtier modulaire contenant un transducteur piézoélectrique détectant les signaux acoustiques indiquant la cavitation. Le capteur de cavitation modulaire est muni d'électrodes qui engagent des contacts à ressort dans l'ouverture filetée lorsque le boîtier modulaire est vissé dans l'ouverture filetée. Un capteur endommagé peut être dévissé et remplacé sans connecteur ou soudage.
