Coronary stents are the most commonly used treatment in the United States to repair narrowed or weakened arteries. The ability to visualize the stent during the stenting procedure and post-surgery is crucial to correctly place the stent with respect to the vessel stenosis, and to identify its position within the vessel wall. Current imaging modalities suffer from low contrast, resolution and/or unfavorable artifacts that can inhibit correct visualization of the stent in the artery. We demonstrated the effectiveness of a combined intravascular photoacoustic and intravascular ultrasound imaging method for high resolution and sufficient contrast imaging of commercial stents with respect to the vessel wall.
