Echocardiography. 2003 Oct;20(7):623-35. doi: 10.1046/j.1540-8175.2003.t01-1-03031.x.
Three-dimensional echocardiography has multiple advantages over two-dimensional echocardiography, such as accurate left ventricular quantification and improved spatial relationships. However, clinical use of three-dimensional echocardiography has been impeded by tedious and time-consuming methods for data acquisition and post-processing. A newly developed matrix array probe, which allows real-time three-dimensional imaging with instantaneous on-line volume-rendered reconstruction, direct manipulation of thresholding, and cut planes on the ultrasound unit may overcome the aforementioned limitations. This report will review current methods of three-dimensional data acquisition, emphasizing the real-time methods and clinical applications of the new matrix array probe.
三维超声心动图相对于二维超声心动图具有多种优势，例如准确的左心室定量分析以及改善的空间关系。然而，三维超声心动图的临床应用受到数据采集和后处理方法繁琐且耗时的阻碍。一种新开发的矩阵阵列探头，它允许通过即时在线容积渲染重建进行实时三维成像、直接操作阈值以及在超声设备上进行切面操作，可能会克服上述局限性。本报告将回顾当前的三维数据采集方法，重点介绍新矩阵阵列探头的实时方法和临床应用。
