摘要: Coronary artery imaging is a demanding application for any non-invasive modality. On the one hand, high temporal resolution needed to virtually freeze cardiac motion and avoid artifacts in images. other sufficient spatial — at best sub-millimeter required adequately visualize small complex anatomical structures such as coronary arteries. The complete tree has be examined within short breath-hold time breathing limit amount of contrast agent if necessary. In 1984, electron beam computed tomography (EBCT) was introduced modality diagnosis disease (Boyd Lipton 1982; Agatston et al. 1990; Achenbach 1998, Becker 2000a). 100 ms allowed motion-free anatomy diastolic heart phase even higher rates.
