超声激发生物组织声发射的原理及应用

The principle and applications of ultrasound-stimulated acoustic emission in tissue

介绍一种利用双频共焦超声波获取组织内部特性信息的新方法-超声激发声发射(USAE)。本文着重说明了USAE的基本工作原理,然后介绍了USAE在医学成像和组织无损测温两方面的重要应用。最后指出了一些有待研究的问题。

A new method called Ultrasound-stimulated acoustic emission (USAE) is introduced, which uses confocal bi-frequency ultrasound waves to obtain some information of tissue properties. The basic principle of USAE is explained emphatically, and then two important applications of USAE in medical imaging and in noninvasive measurement of tissue temperature are presented. Finally, some problems to be studied are raised.
