Introduction : Snap Shot Freeze (SSF) is a novel motion correction algorithm based on non-rigid registration in coronary CTA.The purpose of this study is to evaluate the influence of baseline image quality on the motion correction effect of SSF.Method : Twenty cases of patients underwent coronary CTA using a 64-row MDCT scanner (GE, Discovery HD750).Single sector reconstruction was used to select the best reconstruction phase.SSF reconstruction and motion correction was performed based on the reconstructed single sector images.
