An Unsupervised Deep Learning Framework for Retrospective Gating of Catheter-Based Cardiac Imaging

<div>Curvature of vessel wall borders in L-view slices of nongated and gated (a) IVOCT and (b) IVUS image sequences. Compared to the nongated sequences, the curvature of the vessel wall borders and its variation in the gated sequences are significantly reduced, indicating that the continuity and smoothness of the vessel wall are significantly improved.</div>
