Three-dimensional (3-D) echocardiography has been an important research goal ever since the introduction of two-dimensional (2-D) echocardiography. Most approaches towards 3-D echocardiography were off-line and based on the sequential rotational scanning and acquisition of multiple cross-sectional images together with external or internal reference systems. These approaches were limited by long acquisition and analysis time in combination with poor image quality. Recently, improvements in the matrix array technology have significantly increased spatial and temporal resolution of second-generation real-time 3-D transducers. Clinical use of modern 3-D echocardiography is boosted by the marked reduction in acquisition time and the unique possibility of on-line rendering on the ultrasound system. The integration and future quantification of new parameters together with on-line review allows new insights into cardiac function, morphology and synchrony that offer great potentials in the evaluation of right and left global and regional function, diagnosis of small areas of ischemia, congenital and valvular heart disease and effects of biventricular pacing in dilated heart asynchrony. This report will review current and future applications of 3-D data acquisition, emphasizing the real-time methods and clinical applications of the new matrix array transducer.
自从二维超声心动图问世以来，三维（3-D）超声心动图一直是一个重要的研究目标。大多数三维超声心动图方法都是离线的，基于多个横截面图像的顺序旋转扫描和采集，并结合外部或内部参考系统。这些方法受到采集和分析时间长以及图像质量差的限制。最近，矩阵阵列技术的改进显著提高了第二代实时三维换能器的空间和时间分辨率。采集时间的显著缩短以及在超声系统上进行在线渲染的独特可能性推动了现代三维超声心动图的临床应用。新参数的整合和未来量化以及在线审查为心脏功能、形态和同步性提供了新的见解，在评估左右心室整体和局部功能、诊断小面积缺血、先天性和瓣膜性心脏病以及双心室起搏对扩张型心肌病不同步的影响方面具有巨大潜力。本报告将回顾三维数据采集的当前和未来应用，重点介绍新型矩阵阵列换能器的实时方法和临床应用。
