Abstract
Studies with both plant and animal tissues show that, when the tissues contain micron-sized, stabilized gas bodies, pulsed ultrasound can produce damage at very low time-averaged intensities. However, it is the temporal peak intensity rather than the time-averaged intensity that is closely correlated with the effects observed. The data suggest that there may be thresholds for damage at peak intensities within an order of magnitude of 10 W/cm2.
摘要
对植物和动物组织的研究表明，当组织中含有微米级稳定气体泡时，脉冲超声在极低的时间平均强度下就能造成损伤。然而，与所观察到的效应密切相关的是时间峰值强度而非时间平均强度。数据表明，峰值强度造成损伤可能存在阈值，其量级在10W/cm²左右。
