超高速超声成像的研究进展

Research progress of ultrafast ultrasound imaging

近年来发展迅速的超高速超声成像可获得高达数千至上万帧/秒的帧频,具有绝佳的时间分辨力,可以实现传统超声的帧频无法获得的成像结果。本文对超高速成像的基本原理及其目前在剪切波弹性成像、多普勒成像、心血管成像、造影成像等领域的应用进展进行综述。

Ultrafast ultrasound imaging with frame rates up to 10 000frames/s has recently become a new research focus.Such a high frame rate offers excellent temporal resolution and achieves otherwise unattainable results.The principle of ultrafast ultrasound imaging and its application in several areas such as shear wave elastography,Doppler imaging,cardiovascular imaging and contrast imaging were reviewed in this article.
