Optical Coherence Tomography What it is and How it Works Slide 2
What is Intravascular OCT? An optical imaging modality that uses
near-infrared light for high-resolution imaging of vessel anatomy,
tissue microstructure and stents. Key Features: Uses light, not
sound Does not use X-ray Image acquisition is fast Images acquired
are sharp, detailed and easy to interpret 2 Images: Drs. Grube,
