诊断超声图像的质量有时受到器官和组织内过度声衰减的限制。超声回波增强器通过增加反射信号的强度来帮助克服这种限制。声学原理表明，最有效的增强剂是充气微泡。生产对于常规临床使用足够稳定的微泡悬浮液的问题已经以几种方式克服。新的发展正在导致具有主动声学响应的增强剂，并且对特定器官和组织具有亲和力。(C)1997 Elsevier Science爱尔兰有限公司
The quality of diagnostic ultrasound images is sometimes limited by excessive acoustic attenuation within the organs and tissues. Ultrasound echo-enhancers help to overcome that limitation by increasing the intensity of the reflected signal. Acoustic principles dictate that the most effective enhancers are gas-filled microbubbles. The problem of producing a microbubble suspension stable enough for routine clinical use has been overcome in several ways. Newer developments are leading to enhancers with an active acoustic response and that have affinities for specific organs and tissues. (C) 1997 Elsevier Science Ireland Ltd.
