| Abstract: | In muhilayer 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. ECG gating technology includes foresight ECG gating and retrospective ECG gating. The principle, methods and mutual image reconstruction are introduced in this paper. |
