Digital signal and image processing techniques are acquiring an increasingly important role in the generation and analysis of cardiac images. This is particularly true of 2D echocardiography, in which image acquisition, manipulation, and storage within the echocardiograph, as well as quantitative analysis of echocardiographic data by means of "off-line" systems, depend upon digital techniques. The increasing role of computers in echocardiography makes it essential that echocardiographers and technologists understand the basic principles of digital techniques applied to echocardiographic instrumentation and data analysis. In this article, we have discussed digital techniques as applied to image generation (digital scan conversion, preprocessing, and postprocessing) as well as to the analysis of image data (computer-assisted border detection, 3D reconstruction, tissue characterization, and contrast echocardiography); a general introduction to off-line analysis systems was also given. Experience with other cardiac imaging methods indicates that digital techniques will likely play a dominant role in the future of echocardiographic imaging.
数字信号与图像处理技术在心脏图像的生成与分析中发挥着越来越重要的作用。二维超声心动图尤其如此，其中超声心动图仪内的图像采集、处理和存储，以及借助“离线”系统对超声心动图数据进行定量分析，均依赖于数字技术。计算机在超声心动图中日益重要的作用使得超声心动图医师和技术人员必须了解应用于超声心动图仪器和数据分析的数字技术的基本原理。在本文中，我们讨论了应用于图像生成（数字扫描转换、预处理和后处理）以及图像数据分析（计算机辅助边界检测、三维重建、组织特征分析和对比超声心动图）的数字技术；还对离线分析系统进行了概述。对其他心脏成像方法的经验表明，数字技术可能在超声心动图成像的未来发挥主导作用。
