Fig. 2: In vivo imaging in a flexed forelimb model of brachial porcine artery.

a The dotted line highlights the estimated path taken by the Vis-M device through the vessel tortuosity. b HF-OCT microscopy shows the external elastic lamina (arrowheads) and the individual layers of the vessel wall (arrows). A bright tunica intima is followed by a dark tunica media and a bright adventitia (inset). The asterisks denote the ostia of two side-branches, with diameters of ~0.2 and 0.7 mm, respectively. c The arrow indicates the eccentric position of the HF-OCT device in the arterial lumen. The image shows a uniform illumination and absence of NURD artifacts. Imaging in a flexed forelimb swine model was repeated in a total of n = 16 arteries from all animals included in this study (n = 8). The scale bar on DSA image is equal to 1 cm (a). HF-OCT images scale bars are equal to 1 mm (b and c), and 0.5 mm in the inset.
