OCT
Optical Coherence Tomography
Sketch of working principle
- • TDOCT: MIT (J.G. Fujimoto et al.) in 1991.
- • FDOCT has been researching since 1995.
Advantages
- • Noninvasive in vivo imaging
- • High spatial resolution
- • Broad dynamic range
Disadvantages
- • Coherent noise
- • Dispersion mismatch

Optical Coherence Tomography
[E.Regar J.A. et al., Cardio. Radi. Med. v.4, 2003]
- • Resolution 10 times higher than Ultrasound, MRI
- • Penetration depth deeper than CSM
- • Enough niche market against other imaging technologies
