Intravascular OCT: Current State and Future Directions

This chapter reviews the current state of intravascular optical coherence tomography (IV-OCT) technology, including swept-source system architectures, catheter design principles, and clinical applications in interventional cardiology. We discuss emerging capabilities including spectroscopic analysis, polarization-sensitive imaging, and integration with other intravascular modalities. Future directions in miniaturization, multimodal catheters, and artificial intelligence-assisted interpretation are examined.
