亚秒级螺旋计算机断层扫描 (CT) 为改善心脏成像提供了巨大潜力。新的多行探测器技术显着增强了这一潜力。因此，我们开发并验证了专用的心脏重建算法，利用心电图 (ECG) 信息通过亚秒级多层螺旋 CT 对心脏进行成像。单切片心脏 z 插值算法 180 度 CI 和 180 度 CD [Med。物理。 25, 2417-2431 (1998)] 被推广以允许 M 切片扫描仪对心脏进行成像。研究了两类算法：180 度 MCD（多切片心脏 Delta）、180 度 + Delta 数据与 Delta 的部分扫描重建
Subsecond spiral computed tomography (CT) offers great potential for improving heart imaging. The new multi-row detector technology adds significantly to this potential. We therefore developed and validated dedicated cardiac reconstruction algorithms for imaging the heart with subsecond multi-slice spiral CT utilizing electrocardiogram (ECG) information. The single-slice cardiac z-interpolation algorithms 180 degrees CI and 180 degrees CD [Med. Phys. 25, 2417-2431 (1998)] were generalized to allow imaging of the heart for M-slice scanners. Two classes of algorithms were investigated: 180 degrees MCD (multi-slice cardio delta), a partial scan reconstruction of 180 degrees+ delta data with delta
