Same CT image, different rooms – why displays look different
2025-10-09
The same CT study should present the same grayscale—room to room. If it doesn’t, the issue isn’t the scan; it’s the display pipeline: calibration, luminance stability, signal path, and ambient light. This guide maps the risks and a practical, auditable fix—GSDF calibration, stabilized luminance, 20–40 lux reading rooms, matched viewer presets, and routine QA—so one CT has one look everywhere.
