Rotational scanning from the subxiphoid position is an image acquisition technique used for reconstruction of dynamic three-dimensional echocardiographic images in infants and small children. The orientation of the heart within the three-dimensional data set is variable and dependent on the image plane at which rotational scanning was initiated. We describe an image acquisition technique that standardizes the orientation of the heart within the three-dimensional data set, thereby permitting a systematic approach to the reconstruction of three-dimensional renderings. Thirteen infants and small children with congenital heart disease were studied by this approach. Illustrative examples are provided. The average time required to derive a three-dimensional rendering was 37 +/- 9 minutes. We conclude that subxiphoid rotational scanning by a systematic approach to image acquisition and reconstruction can be applied successfully to the derivation of three-dimensional renderings of congenital cardiac defects.
剑突下位置的旋转扫描是一种用于重建婴幼儿动态三维超声心动图图像的图像采集技术。心脏在三维数据集中的方向是可变的，并且取决于开始旋转扫描的图像平面。我们描述了一种图像采集技术，该技术可使心脏在三维数据集中的方向标准化，从而允许采用系统的方法来重建三维图像。通过这种方法对13例患有先天性心脏病的婴幼儿进行了研究，并提供了示例。获得三维图像所需的平均时间为37±9分钟。我们得出结论，通过系统的图像采集和重建方法进行剑突下旋转扫描可以成功应用于先天性心脏缺陷三维图像的获取。
