Effect of a novel motion correction algorithm (SSF) on the image quality of coronary CTA with intermediate heart rates: segment-based and vessel-based analyses.
TL;DR: The SSF algorithm can provide acceptable diagnostic image quality in coronary CTA for patients with intermediate HR and provided significantly higher interpretability of the coronary segments than bi-sector reconstructions.
