Abstract
In a method of identifying gaseous bubbles in a liquid, an ultrasound contrast agent is introduced into the liquid so as to form gaseous bubbles in the liquid. A first ultrasound pulse centered at a first frequency is directed onto the bubbles so as to cause the bubbles to undergo a first oscillating size change and produce a first oscillating echo signal corresponding thereto. The first oscillating echo signal produced by the bubbles is detected, and the bubbles are identified based upon the detected first echo signal.
