Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is an catheter-based intravascular imaging technology that uses low-coherence light interferometry, using near-infrared light, to capture high-resolution 2-D and 3-D image reconstructions of coronary arteries. It has a lower level of tissue penetration than intravascular ultrasound (IVUS), but offers much higher resolution images of the tissues. It is used to determine the nature and extent of the atheroscleratic disease in the vessel wall, to assess in-stent restenosis and aid catheter procedure navigation in the cath lab.

bioresorbable stent, bioabsorbable stent, Absorb BVS, visualizing bioresorbable stents

A comparison of how the Abbott Absorb BVS appears with intravascular ultrasound (IVUS) on the left, and optical coherence tomography (OCT) of the right. The stent is difficult to visualize and sizing is critical, so both modalities can help in bioresorbable stent measurements and to confirm stent apposition. Left image from the Volcano IVUS system and the right image from St. Jude Medical's OCT system.

The dual catheter OCT-IVUS imaging device can be inserted into an artery to simultaneously capture an infrared image of the arterial wall (OCT, at left) and an ultrasound image (IVUS, right) that doctors use to determine the potential that a plaque is susceptible to rupture that could cause a heart attack or stroke.
