What is Intracoronary optical coherence tomography?

Intracoronary optical coherence tomography is an endoscopic-based application of optical coherence tomography. Analogous to intravascular ultrasound, intracoronary OCT uses a catheter to deliver and collect near infrared light to create cross-sectional images of the artery lumen and wall. Intracoronary OCT creates images at a resolution of approximately 15 micro-meters, an order of magnitude improved resolution with respect to intravascular ultrasound and X-ray coronary angiogram.

IVOCT visualization of arteries inner lumen can help physician to understand morphology and plan treatment accordingly. IVOCT has been used as guidance for angioplasty intervention of coronary arteries, including optimization of stent implantation.
