Fig 1.
Samples of IVUS-VH figures and segmented contour plots, smoothed contour plots.
Plots also include X-ray angiographic image and stacked segmented contours showing the 3D vessel geometry. Colors used in IVUS-VH: Red—necrotic core; White—dense calcium; Dark Green–Fibrous; Light Green—Fibro-Fatty.
