Abstract
Methods, devices and systems, including computer-implemented methods for building a lipid core plaque (LCP) cap collagen structural integrity classifier are described. 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 the presence of an LCP is determined. Collagen structural integrity indicator data associated with the blood vessel wall are determined. The LCP cap collagen structural integrity classifier is generated based on the reflectance spectrum and the collagen structural integrity indicator data.
