Abstract
Described are methods, systems, and apparatus, including computer program products for examining a blood vessel wall. The blood vessel wall is illuminated with near-infrared light. Reflected near-infrared light from the blood vessel wall is received. A reflectance spectrum based on the reflected near-infrared light from the blood vessel wall is determined. Whether the reflectance spectrum is indicative of a presence of a lipid core plaque (LCP) by applying an LCP classifier to the reflectance spectrum is determined. A thickness of an LCP cap is determined by applying an LCP cap thickness classifier to the reflectance spectrum if the reflectance spectrum is indicative of the presence of the LCP. Indicia of the thickness of the LCP cap are displayed.
