In multilayer spiral CT heart and coronary artery imaging, image data are acquired by ECG gating technology when heart beats slowest so as to restrain pulsation pseudo-image.
在多层螺旋CT心脏及冠状动脉成像中，利用心电门控制技术在心脏运动最慢的时期采集图像数据，实线抑制心脏运动伪影的目的。
Methods: Plain and enhanced 16-slice helical ct imaging was studied with retrospective ECG gating in 45 in-patients with coronary heart disease affirmed or suspected in clinic.
方法：对45例临床诊断或可疑冠心病的住院患者行16层螺旋ct冠状动脉回顾性心电门控平扫及增强扫描。
