本研究的目的是评价双源CT冠状动脉成像时运动图算法在自动选择最佳重建相位窗时的效果。50例连续病人的影像数据应用运动图算法确定收缩期及舒张期最佳重建相位窗。应用手动法确定最佳重建窗时,扫描数据于R-R间期每隔5%的相位进行一次重建。
The purpose of this study was to evaluate the effect of the kinematic algorithm in dual-source CT coronary angiography on the automatic selection of the optimal reconstructed phase window. Image data of 50 consecutive patients The motion map algorithm was used to determine the optimal reconstructed phase window for systole and diastole. When manually determining the best reconstruction window, the scan data is reconstructed every 5% of the R-R intervals.
