      Intravascular optical coherence tomography (OCT), originally described in the early 1990s by David Huang, was firstly applied in the field of ophthalmology [1] and named OCT by James Fujimoto. In 1996, the Massachussets General Cardiology group [2] applied a catheter‐based modification of this technology to image coronary arteries. Subsequent advances in OCT technology enabled faster image acquisition rates, sufficient for its in vivo application in humans.

      OCT is a high‐resolution imaging technology that employs advanced fiber optics to create images with a bandwidth in the near‐infrared spectrum with wavelengths ranging from 1250 to 1350 nm. The light that illuminates the vessel is absorbed, backscattered or reflected, by tissue structures at different degrees. Like for intravascular ultrasound (IVUS) images are formed by measuring magnitude and time delay of the reflected backscattered light signal [3]. The speed of light (3×108 m/s), however, is several orders of magnitude faster than the speed of sound (1.5×103 m/s). Compared with IVUS, OCT offers a 10 times higher image resolution, with an axial resolution of 10–20 μm. The price to pay for this high resolution is a reduced penetration depth into tissue and the need to create a transient blood‐free field of view during imaging acquisition. The tissue penetration is limited to 1–3 mm compared to 4–8 mm achieved by IVUS [4]. Early versions of the technology used time domain (TD) detection, while the second‐generation systems using Fourier domain (FD) significantly improved the signal‐to‐noise ratio and allowed high speed pullbacks with faster acquisition [5]. All commercially available systems (Ilumien OptisTM Abbott/LightLab Imaging Inc., USA, Fastview Lunawave® Terumo, Japan) now employ frequency‐domain OCT, which enables rapid imaging of long segments during short injections for blood clearance maintaining good longitudinal resolution.
