Plaque geometry and dimensions. d _w is the arterial wall thickness, d _p is the plaque thickness, d _mp is the macrophage rich layer thickness, l _f is the thickness of the fibrous cap. l _p and l _mp represent the extension or length of the plaque and the macrophage layer in the longitudinal direction, respectively. The location x _i = x/l _p of 4 observation points is presented. Point A corresponds to the center of the plaque (x _A = 0.5), point B presents a point at x _B = 0.65; point C is defined at x _C = 0.7; and point D is the ending point of the plaque (x _D = 1).
