    Abstract

    The shear stresses in the vicinity of gaseous microbubbles in tissue irradiated by continuous and transient ultrasonic fields typical of those used in diagnostic practice have been calculated from a solution of the equation of motion of the bubble. The assumptions and limitations of the model have been considered, and within these limits, it appears that the steady stresses produced may lie above reported thresholds for biological effects. It would appear from the data in the literature that not all the biological effects reported may be caused by stresses resulting from acoustic streaming.
