随着电子计算机技术和声学理论研究的深入,超声换能器的研制和显示方法已取得长足的进步,实时三维超声心动图(real-time or live three-dimensional echocardiography)是心脏超声成像领域内的一项重大的技术突破,它为临床医师提供了一个能无创地观察心脏解剖立体形态的新视窗。这一技术不仅对于心脏疾患的诊断具有巨大意义,而且在介入治疗方面也将发挥重要作用。现就其成像方式的演进、临床应用现状及其发展前景探讨如下。
With the development of computer technology and acoustic theory, great progress has been made in the development and display of ultrasonic transducers. Real-time or live three-dimensional echocardiography is the field of cardiac ultrasound imaging A major technological breakthrough, it offers clinicians a new window to observe the stereological morphology of the heart without invasiveness. This technique is not only of great significance for the diagnosis of heart disease, but also plays an important role in interventional therapy. Now on the evolution of imaging methods, clinical application of the status quo and its development prospects are as follows.
