Abstract
The present invention is directed to a method and apparatus of cardiac CT imaging. The present invention utilizes ECG signals as well as mechanical motion signals of a cardiac region of a subject to correlate CT data acquired of the subject with the phases of the subject's cardiac region. The present invention contemplates measuring mechanical gatings of the heart by measuring changes in pressure, sound, or blood flow acceleration within the cardiac region. The mechanical gatings are then used with ECG data to correlate acquired imaging data with phases of the cardiac region for subsequent image reconstruction.
