In this chapter, we review 3D ultrasound-based methods for segmentation of carotid plaques and their use in quantifying plaque composition using image texture metrics. Specifically, we review algorithms used to segment the media-adventitia and lumen-intima of CCA, internal carotid artery (ICA), and external carotid artery (ECA). We also review methods, which have used these segmented boundaries to provide information on plaque composition using image texture metrics.
