<unk>  (OCT) (or, more generally, intravascular<unk><unk><unk> , IVOCT), is an endoscopic-based application of<unk><unk><unk> . Analogous to intravascular ultrasound,<unk>  OCT uses a catheter to deliver and collect near infrared light (e.g., 1,300 nm) to create cross-sectional images of the artery lumen and wall.<unk>  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.
