抄録

In a cavitation-enhanced HIFU treatment, it is important to avoid generating bubbles larger than the resonance size through the coalescence of bubbles induced by the Bjerknes forces. In this study, the effect of the temporal change in pressure field to suppress the bubble coalescence at the nodes and antinodes in the pressure field was investigated by testing the effect of transmission alternating split apertures on the cavitation region and temperature rise.
