本文综述了气泡和气泡球作为超声造影剂的性能。 与刚性球体相比，气泡是上级散射剂，并且它们提供了可以以各种方式利用的许多有用的性质。 对它们的声速、背向散射强度、二次谐波发射和共振频率的分析为开发具有潜在临床应用价值的超声心动图研究用造影剂开辟了新的前景。
The behaviour of gas bubbles and gas encapsulated spheres as echographic contrast agents is reviewed. Compared with rigid spheres, gas bubbles are superior scattering agents and they offer a number of useful properties which can be exploited in a variety of ways. The analysis of their velocity of sound, back-scatter intensity, second harmonic emission and resonant frequency opens up new perspectives in the development of contrast agents for echocardiographic research with potential clinical applications.
