目的心率>65次/min者心脏CT影像重建存在困难。收缩期末被认为是最佳重建时相,但影像质量仍不稳定。利用双源CT(DSCT)及83ms的时间分辨率,对收缩期末运动伪影最小时
The purpose of heart rate> 65 beats / min cardiac CT image reconstruction difficulties. The end of systolic phase is considered as the best reconstruction phase, but the image quality is still not stable. Using dual-source CT (DSCT) with a temporal resolution of 83 ms, the minimum systolic motion artifact
