我们已经调查了表面振动所产生的超声激励个别未封装的微米级气泡。此外，我们提出了表面模式（n=2和3）观察磷脂涂层超声造影剂通过激发径向模式在1和4 MHz之间的频率激发。甚至更高的振动模式（高达模式5），观察到涂层微泡在10和19 MHz的声波频率。表面模式的医学超声的潜在相关性进行了讨论，包括目前的理论模型的超声造影剂的可能影响。
We have investigated surface vibrations generated by ultrasound excitation of individual unencapsulated micron-sized bubbles. In addition, we present surface modes (n=2 and 3) observed for phospholipid-coated ultrasound contrast agents excited through excitation of radial modes at frequencies between 1 and 4 MHz. Even higher modes of vibration (up to mode 5) are observed for coated microbubbles at insonation frequencies of 10 and 19 MHz. The potential relevance of surface modes for medical ultrasound is discussed, including the possible implications for current theoretical models of ultrasound contrast agents.
