在二维超声发展的同时,对心肌结构用背向反射积分(IBS)方法,从声像特点上作出定量的工作也在进行着。本文对此技术的声学原理、实验室结果及临床应用作一简介。
Simultaneously with the development of two-dimensional ultrasound, the use of backscatter integration (IBS) for myocardial structures to quantify sound characteristics has also been underway. This article gives an introduction to the acoustic principle, laboratory results and clinical application of this technique.
