Cavitation occurrence around ultrasonic dental scalers [PDF]
Ultrasonics Sonochemistry, 2009 Ultrasonic scalers are used in dentistry to remove calculus and other contaminants from teeth. One mechanism which may assist in the cleaning is cavitation generated in cooling water around the scaler. The vibratory motion of three designs of scaler tip in a water bath has been characterised by laser vibrometry, and compared with the spatial ...

Ultrasonic Detection of Cavitation at Catheter Tips [PDF]
The Journal of the Acoustical Society of America, 1969 To assist in the identification of inner heart structures during ultrasonic cardiac diagnosis, various liquids have been injected through catheters into heart chambers. Each injection produces a cloud of ultrasonic echoes within the blood-filled catheterized chamber.
