A line scan report in OCT primarily shows which of the following?

• A. Vessel density
• B. Scan thickness
• C. Noise level
• D. Color map

Answer: (B)

A line scan report is about measuring how thick a tissue layer is along a single scanned line. The OCT system detects the boundaries of a layer (like where the retina ends and a specific layer begins) and computes the distance between those boundaries at each point along that line. The result is a thickness profile, showing how thickness varies across the line. This is what clinicians use to spot thinning or swelling in a targeted region. Vessel density comes from perfusion imaging (OCTA) rather than a standard line scan; it isn’t the primary data shown in a line scan report. Noise level is more about image quality or signal-to-noise rather than a direct thickness readout. A color map is a regional visualization that represents thickness over an area, which is broader than the one-line thickness profile provided by a line scan.
