Three-dimensional surface images of the human heart may be produced from magnetic resonance imaging. These examinations are used in the evaluation of congenital heart disease for preoperative planning and postoperative evaluation. Computer graphics software has been adapted to produce three-dimensional images of the beating heart from contiguous two-dimensional serial EKG-triggered magnetic resonance image data sets. The natural boundary between flowing blood and cardiac tissue serves to outline cardiac structures. The techniques for producing these images and pitfalls in the operation of the system as well as examples of their application to the study of patients with congenital heart disease are outlined in this article.
人体心脏的三维表面图像可通过磁共振成像生成。这些检查用于先天性心脏病的评估，以进行术前规划和术后评估。计算机图形软件已被改编，用于从连续的二维系列心电图触发磁共振图像数据集中生成跳动心脏的三维图像。流动血液与心脏组织之间的自然边界用于勾勒心脏结构。本文概述了生成这些图像的技术、系统操作中的陷阱以及它们在先天性心脏病患者研究中的应用实例。
