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.

SpectraWave is developing a a new intravascular imaging system that combines two currently available modalities. This likely includes optical coherence tomography (OCT), left, which can define structures within the vessel and vessel wall. Near infrared spectroscopy (NIRS), right, enables a spectral chemical analysis of the vessel walls to show areas of high lipid content, and specifically can identify lipid-core plaques that are associated with heart attack-causing plaque ruptures.

Angiography with a co-registered view of pressure drops according iFR readings in a coronary vessel. The DEFINE PCI study showed patients had improved outcomes and less recurrent chest pain at one year using iFR physiologic measurements combined with landmarks shown on angiographic imaging to better guide therapy.
