Although tomographic imaging has been very successful in cardiology,the quantitation of volumes, surfaces, and masses,as well as understanding of complex morphologies would improve by three-dimensional imaging. This review focuses on approaches to 3-D reconstruction from transesophageal echocardiography. In the past, several attempts using either stepwise parallel translation or stepwise rotation of the transducer have been made. In vitro and, to a limited extent, in vivo studies have confirmed high accuracy in calculating left ventricular volumes in such manner. Complex cardiac structures and their motion, such as the mitral annulus, mitral leaflets, atrial septal defects, and others have been reconstructed from patient studies. Although potentially a powerful tool for cardiac imaging with promising quantitation capabilities, progress is needed in particular in the field of border detection to make 3-D imaging practical enough for clinical use.
尽管断层成像在心脏病学领域已经非常成功，但三维成像将改善体积、表面积和质量的定量分析，以及对复杂形态的理解。本综述重点关注经食管超声心动图三维重建的方法。过去，人们曾尝试通过换能器的逐步平行平移或逐步旋转来进行三维重建。体外研究以及有限的体内研究已证实，以这种方式计算左心室容积具有很高的准确性。通过患者研究已经重建了复杂的心脏结构及其运动，如二尖瓣环、二尖瓣叶、房间隔缺损等。尽管三维成像作为一种具有前景的定量分析能力的心脏成像工具潜力巨大，但特别是在边界检测领域仍需取得进展，以使三维成像足够实用以用于临床。
