Transthoracic (TTE) and transesophageal (TEE) three-dimensional echocardiography (3DE) is now used in daily clinical practice. Advancements in technology have improved image acquisition with higher frame rates and increased resolution. Different 3DE acquisition techniques can be used depending upon the structure of interest and if volumetric analysis is required. Measurements of left ventricular (LV) volumes are the most common use of 3DE clinically but are highly dependent upon image quality. Three-dimensional LV function analysis has been made easier with the development of automated software, which has been found to be highly reproducible. However, further research is needed to develop normal reference range values of LV function for both 3D TTE and TEE.
经胸（TTE）和经食管（TEE）三维超声心动图（3DE）现在已在临床日常实践中使用。技术的进步提高了图像采集的帧率和分辨率。可以根据感兴趣的结构和是否需要容积分析来使用不同的 3DE 采集技术。左心室（LV）容积的测量是 3DE 在临床上最常见的用途，但高度依赖于图像质量。随着自动化软件的发展，三维 LV 功能分析变得更加容易，该软件已被证明具有高度可重复性。然而，仍需要进一步的研究来为 3D TTE 和 TEE 制定 LV 功能的正常参考范围值。
