- IVUS or OCT-based estimation of FFR. For each OCT image pullback, the lumen of the coronary artery was automatically delineated and the side branches were automatically detected. Subsequently, the cut-plane perpendicular to the side branch center line was reconstructed and the area of the side branch ostium in the cut-plane was computed. Bifurcation fractal laws were then applied to calculate the reference vessel size, i.e., the healthy lumen as if there were no stenosis, in order to correct the natural change in lumen size due to the step-down phenomenon when crossing the bifurcations. The area-preservation model was used in order to follow the mass conservation law, assuming that the flow is incompressible. Also as optical coherence tomography-based fractional flow reserve
