Abstract

Computed tomographic (CT) cardiac imaging in vivo has been hampered by motion of the heart during its cardiac cycle. A technique of post data-acquisition correlation of the angular projection data using the electrocardiogram as a reference signal is described. This method produced seven "stop action" images of the heart and resulted in delineating morphological detail not recognizable on the conventional CT scan.

摘要

在活体中进行计算机断层扫描（CT）心脏成像一直受到心脏在心动周期中运动的阻碍。本文描述了一种利用心电图作为参考信号对角度投影数据进行采集后相关处理的技术。该方法生成了七张心脏的“定格”图像，能够清晰显示传统CT扫描中无法识别的形态细节。
