- 14. How Does OCT-A Work? So smart, so simple OCT image is a structural, cross-sectional, B-scan image. OCT works by sending a long-wavelength light, then detecting changes that occurred on the tissue-reflected light; thereby, it converts the reflected light into an image.
- 15. How Does OCT-A Work? So smart, so simple OCT-A machine captures multiple conventional structural OCT images at the same site. Then, it compares the resulting differences between them (decorrelation): If the imaged area is avascular, then no difference among the multiple images will be detected, and the OCT-A will appear black.
- 16. How Does OCT-A Work? So smart, so simple
- 17. How Does OCT-A Work? So smart, so simple If the imaged area is vascular, intravascular turbulence will cause differences among the multiple images; this difference will be depicted as vessels..
