INTRO TO OCT & SYSYTEM.pptx
- 1. WHAT IS OCT? Optical Coherence Tomography (OCT) is an optical imaging modality that uses near-infrared light to create high-resolution images of tissue microstructure. Optical of or relating to light (visual) Coherence a measure of the correlation between phases of a wave or waves Tomography method of producing images from a series of single planes or slices (Greek “TOMOS=Slice”) 4
- 2. WHAT IS INTRAVASCULAR OCT? OCT is an optical imaging modality that uses near-infrared light (1250-1350nm) 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 5
- 3. INTRAVASCULAR OCT Flexible fiber-optic catheter used for light delivery Fiber rotates to create image frames Fiber pulls back to map vessel segment • The more frames per mm, or high frame density, the higher the resolution 6
