This high-resolution technique with an axial resolution around 15 μm (compared with 150 μm for intravascular ultrasound, IVUS) allows a level of detail never reached before in vivo (Table 1). This has provided new insights into vessel wall-stent interaction 33. Bouma B.E., Tearney G.J., Yabushita H. et al. Evaluation of intracoronary stenting by intravascular optical coherence tomography.
