    Optical Coherence Tomography in Coronary Artery  Disease: Toward Sub cellular Imaging

    Intracoronary optical coherence tomography (OCT) is an interferometric imaging technology that uses near-infrared light to provide cross-sectional images with an axial resolution of 10 μm and a transverse of 20-40 μm in vivo. The imaging capabilities of OCT have enabled visualization of important features of coronary plaque, including thrombus, macrophage, neovascularization, stent implantation and stent strut coverage, which have provided new insights for better understanding of this disease. Frequency domain (FD)-OCT is secondgeneration form of OCT that is able to acquire OCT images at a much higher frame. The high-speed imaging capabilities of FD-OCT have made intravascular OCT practical ...
