Additional complex impedance produced by a liquid environment to such resonators is considered. It was shown experimentally, that for the disk bender resonator this additional impedance can be represented by the sum of two terms: one that is proportional to liquid density and a second one that is proportional to the square root the of viscosity density product. Same model was earlier shown applicable to the tuning fork resonator. Interaction of a resonator of arbitrary shape oscillating in any mode with surrounding fluid is considered theoretically. The conditions on which this impedance model is applicable to any type of a resonator that directly displaces liquid are discussed. These conditions are satisfied for most of flexural resonators available, detailed consideration of tuning fork and disk bender is provided. Sensitivity of flexural resonator response to liquid electrical properties is discussed. Application of disk bender to density and viscosity measurements in strong electrolytes is considered.","PeriodicalId":350384,"journal":{"name":"2000 IEEE Ultrasonics Symposium. Proceedings.

Cavitation, the violent growth and collapse of microscopic bubbles, may be an important mechanism in both stone fragmentation and renal tissue damage during ESWL. In water, a conventional lithotripter generates a cavitation field in a cylindrical volume, /spl sim/1 cm wide/spl times/10 cm long. A dual-reflector lithotripter, consisting of two identical spark-gap lithotripters facing each other and firing simultaneously, creates a more localized cavitation field, /spl sim/3 cm wide/spl times/5 cm long. Stone breakage at the focus, and hemolysis, 2-cm from the focus, were assessed using both conventional lithotripsy (CL) and dual-reflector lithotripsy (DRL). Following exposure to 100 shots of DRL, the number of stone fragments >1.5 mm were 17.3/spl plusmn/3.9 at 18 kV, 5.3/spl plusmn/2.8 at 15 kV and 3/spl plusmn/1.7 at 12 kV. Following exposure to 200 shots of CL, the number of stone fragments >1.5 mm were 3.5/spl plusmn/1.9 at 18 kV, 1.6/spl plusmn/0.8 and at 15 kV, and 1.7/spl plusmn/1.1 at 12 kV. Following exposure to 100 shots of DRL, values for hemolysis were 8.1/spl plusmn/2.3% at 18 kV and 4.9/spl plusmn/1.1% at 15 kV. Following exposure to 200 shots of CL, values for hemolysis were 10.9/spl plusmn/3.4% at 18 kV and 7.8/spl plusmn/2.5% at 15 kV. These data demonstrate that, in vitro, DRL results in enhanced stone comminution at the focus and decreased damage to red blood cells a short distance from the focus.","PeriodicalId":350384,"journal":{"name":"2000 IEEE Ultrasonics Symposium.
