(a)在右侧冠状动脉内植入支架的血管造影图。(b)在右侧冠状动脉内植入的支架起作用后的血管造影图。(c)植入支架的血管的断面OCT照片，由于聚合物支架不反射光，因此呈现为清晰的(黑色)菱形。(d)植入支架的血管内超声照片，支架呈现为沿动脉壁周向分布的亮斑[98]。

(a) Angiogram of a stent implanted in the right coronary artery. (b) Angiogram of a worked stent implanted in the right coronary artery (c) Optical coherence tomography image of a blood vessel implanted with the stent. Due to their polymeric nature, struts of BRS do not reflect light and therefore appear as clear (black) rhomboids. (d) Intravascular ultrasound image of a blood vessel implanted with the stent. BRS struts are visualized as brighter foci distributed circumferentially around the arterial wall[98].
