Fig. 4.
Representative images from each of the three 3D reconstruction systems. a Representative pullback 1, a case of agreement by all three systems. White arrows: the guidewire of rewiring into the side branch. Yellow arrows: the undetected stent struts. b Representative pullback 2, a case of disagreement by ver. 1.1. (iv) and (v) are the online cross-sectional OFDI image with the stent struts highlighted. (vi) is the cross-sectional OFDI imaging using in-home software with the stent strut highlighted. The stent struts were not detected sufficiently by ver. 1.1 (iv), whereas they were detected almost perfectly by ver. 1.2 (v) and the offline 3D system (vi)
