Plaque configuration in atherosclerotic artery. The presence of the fibrous cap and lipid within a diseased artery causes the protrusion of the arterial wall into the lumen. A: The morphological configuration of these plaque composites is idealized schematically to facilitate geometrical modeling for validation. B: The definition of a calcification gap is based on distance between the calcification agglomerate and the fibrous cap.
