Detecting Presence of Bubbles Within Simulated Blood Vessels Using a Piezoelectric Ring Set to Oscillate at Matching Resonant Conditions Available to Purchase

A variety of methods have been used to detect and measure the presence and size of bubbles that occur naturally in tubes or blood vessels. These traits have recently produced interest in biomedical fields including drug delivery systems and decompression sickness, among others. To detect and measure bubbles, optical, acoustic, and equivalent bulk properties methods have primarily been used; each exploiting unique characteristics of bubbles [1]. Among these, Doppler techniques based on the backscattering of ultrasound waves, have been used to detect and measure bubbles within fluid media [2,3].
