Endovascular Doppler optical coherence tomography

Dr. Yang’s research group has used endovascular OCT as a vascular imaging tool to provide feedback for carotid artery stenting (Figure 1). Endovascular optical coherence tomography looks at stent placement and visualizes blood flow patterns that are the result of stent-related complications in the human carotid artery.

Figure 1: a) Structural OCT image of a stented carotid artery. Coagulated blood was artificially injected into the vessel and had attached to the stent struts (red arrows). b) The corresponding endovascular OCT image which visualizes Doppler phase contours that could be used to assess the carotid artery. Scale bar: 1 mm. Read more about this research here and here.
