ABSTRACT
Visible size gas bubbles can be produced in an agar based gel when irradiated with either continuous wave (CW) or pulsed ultrasound. It is shown that many aspects of the production of these bubbles can be explained in a qualitative manner by a theoretical model based upon growth of a cavitation nucleus by rectified diffusion. Quantitative predictions for the number of bubbles produced as a function of various parameters tend to be different from measured values by less than an order of magnitude. The results given here provide a useful theoretical basis for the explanation of earlier measurements of ultrasonically induced bubbles in vivo.
