In OCT color mapping, which statement best describes the color interpretation?

• A. White indicates higher reflectivity
• B. White indicates lower reflectivity
• C. White indicates no reflectivity
• D. White indicates motion artifacts

Answer: (A)

In OCT color mapping, the image encodes how much light is backscattered from tissue. The brighter the backscattered signal, the higher the reflectivity, and the display assigns that location a brighter value. White is used for the strongest reflections, so it correctly indicates higher reflectivity. Regions with little or no backscattered light appear dark because there’s little signal to map to brightness. Motion artifacts aren’t part of the reflectivity interpretation—they’re distortions in the image, not a measure of tissue reflectivity.
